如何使用javascript从输入中清除数据属性

Question

How do I clear the userid attribute of a specific input field? Even when I clear the field the userid is not cleared, because I am fetching the data on the basis of the ID in input field of the textbox, it also fetches the data of the userid which is not present in the textbox because it gets stored and is removed only after refresh(f5).

<input id="inputField_0" 
       type="text" 
       class="inputClass ui-autocomplete-input" 
       autocomplete="off" 
       userid="10018" />

Answer 1

You can leverage jQuery's removeAttr method.

$("#inputField_0").removeAttr("userid");

Or if you need a vanilla JS option, you can leverage the element's removeAttribute method.

document.getElementById("inputField_0").removeAttribute("userid"); 

Answer 2
