{{APIRef("DOM")}}
The value property of the {{domxref("Attr")}} interface contains the value of the attribute.
A string representing the attribute value.
The following example displays the current value of the attribute test. Clicking on the button will change it to a different value, and read it again to update the displayed value.
<label test="initial value"></label>
<button>Click me to set test to <code>"a new value"</code>…</button>
<p>
Current value of the <code>test</code> attribute:
<output id="result">None.</output>
</p>
const element = document.querySelector("label");
const button = document.querySelector("button");
const result = document.querySelector("#result");
const attribute = element.attributes[0];
result.value = attribute.value;
button.addEventListener("click", () => {
attribute.value = "a new value";
result.value = attribute.value;
});
