Question

单击按钮时忽略运行代码的最佳方法是什么？我正在尝试以下但我现在没有反应我想要它完成。

if (!document.getElementById('btn_Cancel').getAttribute('onclick')) {
      // code not to be ran when button is clicked
         By default code gets ran when a textbox goes onblur so do not want that code ran when button gets clicked
}

您将要对该元素进行引用，因此每次单击时您都不会查找它，并且您需要一个变量来跟踪它是否被单击：< / p>

var cancelButton = document.getElementById('btn_Cancel'),
    clicked = false;

cancelButton.addEventListener('click', function() { clicked = !clicked; }, false); 

// assuming this is in a loop or something:
if(!clicked) { 
    // running code 
}
else {
   // clicked, do nothing
}

如果围绕onclick声明
