JavaScript-Set text box not editable

We need to create an HTML skeleton first, which can be generated quickly by the compiler.

And then we type the basics in.

Then write JavaScript events to disable functionality

var btn1 = document.getElementById('btn1'); btn1.onclick = function () { var txt = document.getElementById('txt'); txt.disabled = true; }

Optimize it: enter numbers in the text box, click disable and you can't enter numbers in the text box, and then write "enable" function. In fact, the enabling function is almost the same as the disabling function, just change "disabled = true" to "disabled = false", the code is as follows:

var btn1 = document.getElementById('btn1'); btn1.onclick = function () { var txt = document.getElementById('txt'); txt.disabled = true; } var btn2 = document.getElementById('btn2'); btn2.onclick = function () { var txt = document.getElementById('txt'); txt.disabled = false; } The above is "javascript how to set not editable" all the content of this article, thank you for reading!
