let var = 0;
I want to change variable value by html input.
<input type="text" id="input" />
How can I do that 🤔

@kuldeepraj the question doesn't mention PHP at all, so that's not relevant.WOUNDEDStevenJones– WOUNDEDStevenJones2021-07-12 17:18:57 +00:00Commented Jul 12, 2021 at 17:18

<input id="myInput" type="text" onchange="changeV()">
...
let v = 0;
var changeV = ()=>{
v = document.getElementById("myInput").value;
}
****And there's a serious error in your code. "let var = 0;" "var" is a keyword predefined in javascript. Specifically, it is a keyword used in variable declaration. Do not use predefined keywords as variable names.

It doesn't work I use if condition when variable = 0 show input. and if it more than it show all project.
