jQuery-从Ajax检索数据后如何添加关闭按钮？

Question

I have a problem with retrieve data from Ajax. I want to add button "X" to close popup after show data.

I tried to add a button like:

jQuery(".popup").append('<button style="font-size: 150%; color: red; top: 0; right: 0;">x</button>');

in to popup to the user can close my popup.

My code like:

function getData(domain){
    var dataString = "domain=" + domain + "&security="+ mhdomain.security + "&action=getdomain" ;
    jQuery.ajax({
        action: "getDomain",
        type: "post",
        url: mhdomain.ajaxurl,
        dataType: "json",
        data: dataString,
        beforeSend: function(xhr){
            jQuery("#wrapper").append('<div class="popup" onclick="popupout(\'.popup\')"></div>');
            jQuery(".popup").append("<img src='https://i.imgur.com/CH8XnNt.gif' alt='loading' />");  
            jQuery(".popup").fadeIn();
            jQuery(".popup").append('<button style="font-size: 150%; color: red; top: 0; right: 0;">x</button>');
        },
        success : function(data){
            jQuery(".popup").html(data.data);
        },
    });      
};
function popupout(popup){
    jQuery(popup).fadeOut(1000);
    jQuery(popup).remove();
}

My CSS code:

.popup {
    position: fixed;
    display: none;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    z-index: 99999;
    max-width: 780px;
    width: 100%;
    max-height: 480px;
    height: 100%;
    display: inline-block;
    cursor: pointer;
    background-color: white;
    padding: 30px 50px;
    color: black;
    overflow-y: scroll;
    border: 1px solid #f2f2f2;
}

Answer 1

In your beforeSend event you are appending the html which is fine. But it gets replaced in success event. in this line the issue is

jQuery(".popup").html(data.data);

But instead of you just append data.data here also which will fix the issue. like this

jQuery(".popup").append(data.data);

For your question in comment, still you can use beforeSend event. Like this

beforeSend:function(){
// after your codes
jQuery(".popup").append("<img src='loading.gif' class='loading'>");
}

success:function(){
// after your codes
jQuery(".popup").find('.loading').remove();
}

You can tweak the appearance of the images using css. But I shared an idea for how to achieve that

You can add your close button html in success.

 function getData(domain){
    var dataString = "domain=" + domain + "&security="+ mhdomain.security + "&action=getdomain" ;
    jQuery.ajax({
        action: "getDomain",
        type: "post",
        url: mhdomain.ajaxurl,
        dataType: "json",
        data: dataString,
        beforeSend: function(xhr){
            jQuery("#wrapper").append('<div class="popup" onclick="popupout(\'.popup\')"></div>');
            jQuery(".popup").append("<img src='https://i.imgur.com/CH8XnNt.gif' alt='loading' />");  
            jQuery(".popup").fadeIn();
            jQuery(".popup").append('<button style="font-size: 150%; color: red; top: 0; right: 0;">x</button>');
        },
        success : function(data){
            jQuery(".popup").html('<div class="popup" onclick="popupout(\'.popup\')"></div>'+data.data);
        },
    });      
};
function popupout(popup){
    jQuery(popup).fadeOut(1000);
    jQuery(popup).remove();
}

The close button is being overwritten by jQuery(".popup").html(data.data); because you are replacing everything inside of .popup .

I have some of your code in the snippet below using .append instead of .html and your button appears and it works.

I would just put a placeholder in the popup that houses the loading gif and replace that div's html with the data.

 function getData(){ jQuery("#wrapper").append('<div class="popup" onclick="popupout(\\'.popup\\')"></div>'); jQuery(".popup").append("<img src='https://i.imgur.com/CH8XnNt.gif' alt='loading' />"); jQuery(".popup").fadeIn(); jQuery(".popup").append('<button style="font-size: 150%; color: red; top: 0; right: 0;">x</button>'); jQuery(".popup").append('popup data'); }; function popupout(popup){ jQuery(popup).fadeOut(1000); jQuery(popup).remove(); } getData(); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="wrapper" ></div>
