按钮禁用在IE 10中不起作用

Question

I have a save button, and initially when few fields are empty, it remains disable. this is working fine in all browsers but not in IE10. I've tried many things to solve this, but nothing has worked. Any help is appreciated.

var numButtons = document.getElementsByTagName('button').length;
for ( var num = 0; num < numButtons; num++) {

    var buttonName = document.getElementsByTagName('button')[num].innerHTML;

    if (buttonName == "Save" && id == dialogName) {
        document.getElementsByTagName('button')[num].disabled = true;

        break;
    }
}

Answer 1

You have some undefined variables in your above code. I assumed them as following and this is running code for your problem.

window.onload = function () {
   var numButtons = document.getElementsByTagName('button').length;
   for (var num = 0; num < numButtons; num++) {

      var buttonName = document.getElementsByTagName('button')[num].innerHTML;
      var id = document.getElementsByTagName('button')[num].getAttribute("id");;
      if (buttonName == "Save" && id == "dialogName") {
         document.getElementsByTagName('button')[num].disabled = true;

         break;
      }
   }
};

我不知道这是否是相同的问题，但是我遇到了一个问题，即我认为在IE 10中设置禁用属性不起作用。结果是，当我单击它时它被禁用了，只是没有改变样式因此它仍然处于启用状态。
