禁用div单击Ajax start并在Ajax完成时重新启用它 [英] Disable div click on Ajax start and re-enable it on Ajax complete

问题描述

我需要在启动Ajax请求时禁用div（以便它不再接收点击）并在Ajax完成时重新启用它。我还想在这个过程中显示一个加载gif。我认为这可以使用 ajaxStart 和 ajaxStop 来完成。但是，如果我是正确的，这将激发任何启动或停止的Ajax请求。这就是问题所在。我在页面上有多个div，其中任何一个都可以触发Ajax请求。如何禁用/启用单击的特定div，如何使用 ajaxStart ， ajaxStop <显示/隐藏相应的加载gif？ / code>或任何其他方法。请注意，如果这涉及到click事件的绑定/解除绑定，那么建议的方法需要在（）上保持与jQuery 的兼容性。

I need a div to be disabled (so that it no longer receives click) on start of an Ajax request and re-enable it on Ajax complete. I also want a loading gif to be shown during the process. I think that this could be accomplished using ajaxStart and ajaxStop. But, if I am correct these would fire for any Ajax request that start or stops. Here comes the problem. I have multiple div's on a page and anyone of these could trigger an Ajax request. How can I disable/enable the "specific div" that was clicked and how can I display/hide it's corresponding loading gif either using ajaxStart, ajaxStop or any other method. Please note that if this involves binding/unbinding of click event then the method suggested needs to maintain compatibility with jQuery on().

HTML如下所示：

<div class="button white"><img src="loading.gif" /></div>
<div class="button white"><img src="loading.gif" /></div>
<div class="button white"><img src="loading.gif" /></div>

Ajax的Javascript如下所示：

The Javascript for Ajax looks like this:

$('body').on('click', '.button', function(e){
e.preventDefault();

    $.ajax({
        url     : ajaxVars.ajaxurl,
        context : this,
        type    :'POST',
        async   : true,
        cache   : false,
        timeout : 1000,
        data    : { action : 'test_action' },
        success : function(response) {
            if (response == 1) {
                $(this).toggleClass('white').toggleClass('green');
            }
        },
        error   : function() {
            alert(error);
        }
   });
});

推荐答案

禁用按钮，只需更改当前的班级按钮。

to disable button, simply change current class button.

你可以使用这个：

$('body').on('click', '.button', function(e){
e.preventDefault();

$(this).removeClass('button').addClass('disabledbutton');

$.ajax({
    url     : ajaxVars.ajaxurl,
    context : this,
    type    :'POST',
    async   : true,
    cache   : false,
    timeout : 1000,
    data    : { action : 'test_action' },
    success : function(response) {
        if (response == 1) {
            $(this).toggleClass('white').toggleClass('green');
            $(this).removeClass('disabledbutton').addClass('button');
        }
    },
    error   : function() {
        alert(error);
    }

   });
});
