is there any solution to set value for previousvalue attribute for input field using javascript or jquery in the browser console?
I am trying to set the value to input field it's working but at the same time, I need to set the value to previousvalue attribute which is in the tag.
<input type="text" value="" id="test" previousvalue=""/>
to set value i am using document.getElementById("test").value="add";
<input id="input" type="text" value="" previousvalue="" />
document.getElementById('input').addEventListener('change', function() {
this.previousvalue = this.value;
const { value, previousvalue } = this;
console.log(value, previousvalue);
});
If you mean you want value and previousvalue have the same value you can do it like this (imagine input has inp id):
const input = $('#inp')
input.attr('previousvalue', input.attr('value'))
generaly you can set attribute of tag in JQ like below structure:
$(el).attr('attr-name', 'attr-value');\
in pure JS you can do it like this:
el.setAttribute('attr-name', 'attr-value');
