onchange / onclick复选框在IE中不起作用 [英] onchange / onclick in a checkbox doesn't work in IE

问题描述

  chkbx_send_demo.onchange = function（）{
 if（sel_template.selectedIndex< = 0&&chkbx_send_demo.checked == true）{
 alert（Choose a Template）; 
 sel_template.selectedIndex = 1; 
} 
 if（chkbx_send_demo.checked == false）{
 sel_template.selectedIndex = 0; 
} 
} 
  

但它在IE中不起作用。我试图将事件更改为chkbx_send_demo.onclick，但仍然无效。

解决方案

Internet Explorer只会触发onchange事件当复选框失去焦点时（onblur）。

I have the following code, which works perfectly in Chrome/FF:

chkbx_send_demo.onchange = function(){
    if(sel_template.selectedIndex <= 0 && chkbx_send_demo.checked == true){
        alert("Choose a Template");
        sel_template.selectedIndex = 1;
    }
    if(chkbx_send_demo.checked == false){
        sel_template.selectedIndex = 0;
     }
}

But it just won't work in IE. I've tried to change the event to chkbx_send_demo.onclick and it still won't work.

解决方案

Internet Explorer only fires the onchange event when the checkbox loses the focus (onblur). also see here:
