问题描述

我正在寻找启用和停用
div id =dcalc及其子女的方法。

I am looking for a method to Enable and Disable the div id="dcalc" and Its children.

<div id="dcalc" class="nerkheArz"
 style="left: 50px; top: 150px; width: 380px; height: 370px;
 background: #CDF; text-align: center" >
 <div class="nerkh-Arz"></div>
 <div id="calc"> </div>
</div>

我想在加载页面时禁用它们然后点击一下我可以启用它们吗?

I want to Disable them at loading the page and then by a click i can enable them ?

这就是我试过的事情

document.getElementById("dcalc").disabled = true;


推荐答案

你应该可以通过 attr() prop() 函数如下所示:

You should be able to set these via the attr() or prop() functions in jQuery as shown below:

jQuery(< 1.7):

// This will disable just the div
$("#dcacl").attr('disabled','disabled');

// This will disable everything contained in the div
$("#dcacl").children().attr("disabled","disabled");

jQuery(> = 1.7):

// This will disable just the div
$("#dcacl").prop('disabled',true);

// This will disable everything contained in the div
$("#dcacl").children().prop('disabled',true);

//  disable ALL descendants of the DIV
$("#dcacl *").prop('disabled',true);

Javascript:

// This will disable just the div
document.getElementById("dcalc").disabled = true;

// This will disable all the children of the div
var nodes = document.getElementById("dcalc").getElementsByTagName('*');
for(var i = 0; i < nodes.length; i++){
     nodes[i].disabled = true;
}
