The content attribute is always a string even when the expected value should be an integer. For example, to set an <a href="/en-US/docs/Web/HTML/Element/input"><code><input></code></a> element's <code>maxlength</code> to 42 using the content attribute, you have to call <code>setAttribute("maxlength", "42")</code> on that element.</p> <p>The IDL attribute is also known as a JavaScript property. These are the attributes you can read or set using JavaScript properties like <code>element.foo</code>. The IDL attribute is always going to use (but might transform) the underlying content attribute to return a value when you get it and is going to save something in the content attribute when you set it. In other words, the IDL attributes, in essence, reflect the content attributes.</p> <p>Most of the time, IDL attributes will return their values as they are really used. For example, the default <code>type</code> for <a href="/en-US/docs/Web/HTML/Element/input"><code><input></code></a> elements is "text", so if you set <code>input.type="foobar"</code>, the <code><input></code> element will be of type text (in the appearance and the behavior) but the "type" content attribute's value will be "foobar". However, the <code>type</code> IDL attribute will return the string "text".</p> <p>IDL attributes are not always strings; for example, <code>input.maxlength</code> is a number (a signed long). When using IDL attributes, you read or set values of the desired type, so <code>input.maxlength</code> is always going to return a number and when you set <code>input.maxlength</code>, it wants a number. If you pass another type, it is automatically converted to a number as specified by the standard JavaScript rules for type conversion.</p> <p>IDL attributes can <a href="https://html.spec.whatwg.org/multipage/urls-and-fetching.html" class="external" target="_blank">reflect other types</a> such as unsigned long, URLs, booleans, etc. Unfortunately, there are no clear rules and the way IDL attributes behave in conjunction with their corresponding content attributes depends on the attribute. Most of the time, it will follow <a href="https://html.spec.whatwg.org/multipage/urls-and-fetching.html" class="external" target="_blank">the rules laid out in the specification</a>, but sometimes it doesn't. HTML specifications try to make this as developer-friendly as possible, but for various reasons (mostly historical), some attributes behave oddly (<code>select.size</code>, for example) and you should read the specifications to understand how exactly they behave.</p></div></section><section aria-labelledby="boolean_attributes"><h2 id="boolean_attributes"><a href="#boolean_attributes">Boolean Attributes</a></h2><div class="section-content"><p>Some content attributes (e.g. <code>required</code>, <code>readonly</code>, <code>disabled</code>) are called <a href="https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#boolean-attributes" class="external" target="_blank">boolean attributes</a>. If a boolean attribute is present, its value is <strong>true</strong>, and if it's absent, its value is <strong>false</strong>.</p> <p>HTML defines restrictions on the allowed values of boolean attributes: If the attribute is present, its value must either be the empty string (equivalently, the attribute may have an unassigned value), or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace. The following examples are valid ways to mark up a boolean attribute:</p> <div class="code-example"><div class="example-header"><span class="language-name">html</span></div><pre class="brush: html notranslate"><code><div itemscope>This is valid HTML but invalid XML.</div> <div itemscope=itemscope>This is also valid HTML but invalid XML.</div> <div itemscope="">This is valid HTML and also valid XML.</div> <div itemscope="itemscope"> This is also valid HTML and XML, but perhaps a bit verbose. </div> </code></pre></div> <p>To be clear, the values <code>"true"</code> and <code>"false"</code> are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether. This restriction clears up some common misunderstandings: With <code>checked="false"</code> for example, the element's <code>checked</code> attribute would be interpreted as <strong>true</strong> because the attribute is present.</p></div></section><section aria-labelledby="event_handler_attributes"><h2 id="event_handler_attributes"><a href="#event_handler_attributes">Event handler attributes</a></h2><div class="section-content"><div class="notecard warning"> <p><strong>Warning:</strong> The use of event handler content attributes is discouraged. The mix of HTML and JavaScript often produces unmaintainable code, and the execution of event handler attributes may also be blocked by content security policies.</p> </div> <p>In addition to the attributes listed in the table above, global <a href="/en-US/docs/Web/Events/Event_handlers#using_onevent_properties">event handlers</a> — such as <a href="/en-US/docs/Web/API/Element/click_event"><code>onclick</code></a> — can also be specified as <a href="#content_versus_idl_attributes">content attributes</a> on all elements.</p> <p>All event handler attributes accept a string. The string will be used to synthesize a <a href="/en-US/docs/Web/JavaScript/Reference/Functions">JavaScript function</a> like <code>function name(/*args*/) {body}</code>, where <code>name</code> is the attribute's name, and <code>body</code> is the attribute's value. The handler receives the same parameters as its JavaScript event handler counterpart — most handlers receive only one <code>event</code> parameter, while <code>onerror</code> receives five: <code>event</code>, <code>source</code>, <code>lineno</code>, <code>colno</code>, <code>error</code>. This means you can, in general, use the <code>event</code> variable within the attribute.</p> <div class="code-example"><div class="example-header"><span class="language-name">html</span></div><pre

The content attribute is always a string even when the expected value should be an integer. For example, to set an <a href=\"/en-US/docs/Web/HTML/Element/input\"><code><input></code></a> element's <code>maxlength</code> to 42 using the content attribute, you have to call <code>setAttribute(\"maxlength\", \"42\")</code> on that element.</p>\n<p>The IDL attribute is also known as a JavaScript property. These are the attributes you can read or set using JavaScript properties like <code>element.foo</code>. The IDL attribute is always going to use (but might transform) the underlying content attribute to return a value when you get it and is going to save something in the content attribute when you set it. In other words, the IDL attributes, in essence, reflect the content attributes.</p>\n<p>Most of the time, IDL attributes will return their values as they are really used. For example, the default <code>type</code> for <a href=\"/en-US/docs/Web/HTML/Element/input\"><code><input></code></a> elements is \"text\", so if you set <code>input.type=\"foobar\"</code>, the <code><input></code> element will be of type text (in the appearance and the behavior) but the \"type\" content attribute's value will be \"foobar\". However, the <code>type</code> IDL attribute will return the string \"text\".</p>\n<p>IDL attributes are not always strings; for example, <code>input.maxlength</code> is a number (a signed long). When using IDL attributes, you read or set values of the desired type, so <code>input.maxlength</code> is always going to return a number and when you set <code>input.maxlength</code>, it wants a number. If you pass another type, it is automatically converted to a number as specified by the standard JavaScript rules for type conversion.</p>\n<p>IDL attributes can <a href=\"https://html.spec.whatwg.org/multipage/urls-and-fetching.html\" class=\"external\" target=\"_blank\">reflect other types</a> such as unsigned long, URLs, booleans, etc. Unfortunately, there are no clear rules and the way IDL attributes behave in conjunction with their corresponding content attributes depends on the attribute. Most of the time, it will follow <a href=\"https://html.spec.whatwg.org/multipage/urls-and-fetching.html\" class=\"external\" target=\"_blank\">the rules laid out in the specification</a>, but sometimes it doesn't. HTML specifications try to make this as developer-friendly as possible, but for various reasons (mostly historical), some attributes behave oddly (<code>select.size</code>, for example) and you should read the specifications to understand how exactly they behave.</p>"}},{"type":"prose","value":{"id":"boolean_attributes","title":"Boolean Attributes","isH3":false,"content":"<p>Some content attributes (e.g. <code>required</code>, <code>readonly</code>, <code>disabled</code>) are called <a href=\"https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#boolean-attributes\" class=\"external\" target=\"_blank\">boolean attributes</a>. If a boolean attribute is present, its value is <strong>true</strong>, and if it's absent, its value is <strong>false</strong>.</p>\n<p>HTML defines restrictions on the allowed values of boolean attributes: If the attribute is present, its value must either be the empty string (equivalently, the attribute may have an unassigned value), or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace. The following examples are valid ways to mark up a boolean attribute:</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">html</span></div><pre class=\"brush: html notranslate\"><code><div itemscope>This is valid HTML but invalid XML.</div>\n<div itemscope=itemscope>This is also valid HTML but invalid XML.</div>\n<div itemscope=\"\">This is valid HTML and also valid XML.</div>\n<div itemscope=\"itemscope\">\n This is also valid HTML and XML, but perhaps a bit verbose.\n</div>\n</code></pre></div>\n<p>To be clear, the values <code>\"true\"</code> and <code>\"false\"</code> are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether. This restriction clears up some common misunderstandings: With <code>checked=\"false\"</code> for example, the element's <code>checked</code> attribute would be interpreted as <strong>true</strong> because the attribute is present.</p>"}},{"type":"prose","value":{"id":"event_handler_attributes","title":"Event handler attributes","isH3":false,"content":"<div class=\"notecard warning\">\n <p><strong>Warning:</strong> The use of event handler content attributes is discouraged.
