How to change the value of a custom attribute

I have input field as such:

<input type="text" size="40" locationcode="" userid="" id="inputQuery">

How can I select the element using its id and and put value onto userid attribute?

Answer 1

You should use a data- prefix to add a custom attribute, i.e.

data-userid="yourValue"

So in your case you should setup your input like this.

<input type="text" size="40" data-locationcode="" data-userid="" id="inputQuery" />

Then you can use:

$('#inputQuery').attr('data-userid', 'my_value');
