JavaScript - 设置控件的禁用未成功 [英] JavaScript - Set control's disabled not successful

问题描述

在我的项目中，我动态设置了按钮禁用值。但是，该按钮始终不会变灰。当我调试脚本时，按钮的禁用值始终为false，这意味着我的代码在此处起作用（适用于其他一些控件）。什么是导致问题的可能错误来源？谢谢。

In my project, I set a button disabled value dynamically. However, the button is always NOT grayed. When I debugged the script, the button's disabled value is always 'false', which means my code does work here (works well for some other controls). What's the possible bug source that causes the problem? Thanks.

function validate_Panel7() {
    debugger;
    var v = document.getElementById('btnValidate7');
    if (v.disabled == false)
        v = true;
    else
        return;
 }

推荐答案

v.disabled = true;

而不是

instead of

v = true;

会更有意义。

would make much more sense.
