Question

我不明白为什么按钮点击事件发射2次....我在物化css上画了2张卡...当我按下按钮时它检查客户端会话是否开始，并且做某事......否则就会打开一个模态。但点击必须只发射1次，我得到2次警报（“chango”），点击1次......帮助PLS !!，这里是代码：

function list_section(data) {
    var p = JSON.parse(data); // 2 results
    $.each(p, function(i, item) {
    if (item.SECTION_ID == 1) {
        $("#president").append(
            '<div class="col s6">' +
            '\<div class="card medium sticky-action" id="president_'+item.POLITIC_ID+'">' +
            '<div class="card-image waves-effect waves-block waves-light">' +
            '<div class="video-container">' +
            '  <iframe src="' + baseurl + 'public/uploads/' + item.POLITIC_FILE + '" frameborder="0" allowfullscreen controls></iframe>' +
            '</div>' +
            '</div>' +
            '<div class="card-action">' +
            '<span class="card-title activator grey-text text-darken-4">' + item.POLITIC_NAME + '&nbsp' + item.POLITIC_LASTNAME + '<i class="material-icons right">more_vert</i></span>' +
            '<div class="row" style="margin-top:10px;margin-bottom:0px;">' +
            '<div class="col s3">' +
            '<button class=" btn waves-effect modal-trigger waves-light red darken-3 disapprove disapprove_president"  data-target="verification" type="submit" name="action"  ">Desapruebo</button>' +
            '</div>' +
            '<div class="col s3 offset-s4">' +
            '<button class=" btn waves-effect modal-trigger waves-light light-green darken-3 aprove aprove_president" data-target="verification" type="submit" name="action" ">Apruebo</button>' +
             '</div>' +
             '</div>' +
             '</div>' +
             '<div class="card-reveal">' +
             '<span class="card-title grey-text text-darken-4">' + item.POLITIC_NAME + '&nbsp' + item.POLITIC_LASTNAME + '<i class="material-icons right">close</i></span>' +
             '<p>Here is some more information about this product that is only revealed once clicked on.</p>' +
             '</div>' +
             '</div>' +
             '<input type="hidden" id="' + item.POLITIC_ID + '">' +
             '</div>'
        );
        $(document).on('click', '.aprove , .disapprove', function() {
            // $(".aprove , .disapprove").unbind("click");
            //  $(".aprove , .disapprove").on("click", selectKeepFirstOfAll);
            if (sesion != "") {
                if ($(this).attr('class').split(' ').pop() == 'aprove_president') {
                    alert("chango");
                    var data = {}
                    $.ajax({
                        url: baseurl+'result/aprove',
                        type: 'POST',
                        data: data
                    })
                    .done(function() {
                        console.log("success");
                    })
                    .fail(function() {
                        console.log("error");
                    })
                    .always(function() {
                        console.log("complete");
                    });
                }
                else if ($(this).attr('class').split(' ').pop() == 'disapprove_president') {
                }
            }
            else {
                $('#verification').openModal();
            }
        });
    }

将$(document).on('click'...)移到list_section函数之外（使其成为全局）。您正在为您处理的每个部分添加一个onclick处理程序。

按钮单击在模态jquery上执行2次
