Jquery 在 Javascript 中启用和禁用 Div 及其元素

发布于12月08日

我正在寻找一种方法来解决这个问题

<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>

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

This is what i have tried

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

推荐答案

您应该能够通过jQuery中的attr()或prop()函数设置这些，如下所示:

jQuery (< 1.7):

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

or个个

// 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);

or个个

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

or个个

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

Javascript:

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

or个个

// 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;
}
