Question

我有一个由类和数据自定义属性标识的项目列表，如下所示：

<div class="matrix_type" id="12" data-matrix-value="7"></div>
<div class="matrix_type" id="189" data-matrix-value="4"></div>
<div class="matrix_type" id="12090" data-matrix-value="10"></div>
<div class="matrix_type" id="1234" data-matrix-value="2"></div>

我想使用按钮来触发AJAX帖子<button id"send_matrix">Send<button>

单击按钮后，我希望将每个“div”与其值相关联，该对象可以在AJAX请求中与其他数据一起发送。

任何指南？

假设你想获得所有的div并迭代获取所有值，然后将它们发布到＆＃39; one＆＃39;对象，执行以下操作：

$('#send_matrix').click(function(){

    // We post this to the server
    var postObject = {};

    //Get all the divs with the class of 'matrix_type' and iterate through
    $('.matrix_type').each(function(){

        //Get the id of the current div (please make them unique!)
        var id = $(this).attr('id');

        //Get the matrix value of the current div
        var matrixValue = $(this).data('matrix-value');

        //Add a new key-value pair to the postObject
        postObject[id] = matrixValue;
    });


    //Replace this with the url you post the data to
    var url = 'www.something.com' 

    //Post the data to the server
    $.post(url, postObject, function(data, status){

            //Show the result of the attempted post (success or failure)
            alert("Data: " + data + "\nStatus: " + status);
    });
});

使用jquery和Ajax循环遍历元素
