Can I dynamically take a Html element onclick attribute and use it in javascript?

    <input  type="button" onclick="???"    开发者_高级运维id="1" value="Button1"   />

Without knowing what the name of the function in the onclick attribute, can I take the function from the onclick attribute and call it in javascript? If so, how can I do that?

If you just want to trigger click event which will call the onclick function, you can do something like this, using jquery

$('#1').click()

If you're using jQuery:

eval($('#1').attr('onclick'));

This should work, NOTE: IDs are not allowed to start with a number:

<input  type="button" onclick="???"    id="Button1 value="Button1"   />

document.getElementById("Button1").onclick();

Example

The way to do it in jQuery would be $('#Button1').trigger('click') using trigger
