Question

我在div上包含ajax请求的结果并附加到页面中的主div。因此，如果结果数组返回为空，我想提醒用户，说没有找到结果，并提供链接供他们点击。当他们点击一个按类别携带产品的弹出框时会弹出。这里要注意的重要事项是，产品是通过php和ajax脚本派生的。

所以当我使用onclick事件或直接使用时，没有任何反应！但如果我调用空或HTML弹出它会工作。如果我在页面加载或ajax成功函数中触发它，弹出的相同php脚本也会起作用。所以我不明白为什么只有点击它不起作用？

这是我想在“点击”事件

上触发的弹出窗口

 <section id="browse-search-popup" class="mfp-hide white-popup">
 <h1>Browse Courses</h1>
 <a href="">Can't find what you're looking for? Tell us here!</a>
 <h2>First, pick a learning Zone:</h2>
 <div class="row">
   <div class="small-12 medium-8 large-8 medium-centered large-centered columns">
       <ul class="small-block-grid-2 medium-block-grid-2 large-block-grid-2">
       <?php
          $tutor =  new register();
          $data = $tutor->get_maincat();
          $i=0;
          foreach($data as $k=>$v)
          {
              $i++;
              ?>

              <li><div class="mainCat_<?php echo $i;?>" id="<?php echo $v['main_cat_id'];?>"><?php echo $v['main_cat_name'];?></div></li>

              <?php
          }
       ?>
       </ul>
   </div>
 </div>

Ajax请求

$("#search_tutor").submit(function() {
    var data = {
        "action": "test"
    };
    var subject = $("#subject").val();
    data = $(this).serialize() + "&" + $.param(data);

    $.ajax({
        type: "POST",
        dataType: "json",
        url: "/fetch_tutor.php", //Relative or absolute path to response.php file
        data: data,
        success: function(data) {
            $("#contents img.loading").remove();
            var sizy = data.length;
            if(sizy ==0) {
                console.log("sorry, cannot locate");
                $(".simply-popup-link").trigger("click");
                $("#simply-popup").empty();

                //This is where I want to trigger the on click
                $("#simply-popup").append("Unable to locate the subject you entered, please <a href='#'  onclick='browse("+sizy+")' class='yellow'>Browse</a>");

            }
            console.log("size= "+data.length);
            var j=0;
            for (i = 0; i < data.length; i++) {
                ........................
                ......................

浏览功能：

function browse(param) {
    //this would work
    /* $(".simply-popup-link").trigger("click");
       $("#simply-popup").empty();
       $("#simply-popup").append("test only"); */

    // but not this
    $(".browse-search-popup-link").trigger("click");
}

我尝试将页面加载到一个空的弹出框（$（“＃simply-popup”））中，但这样做不起作用：

 $("#simply-popup").load('search/browse.php');

Answer 1

更改

$("#simply-popup").append("Unable to locate the subject you entered, please <a href='#'  onclick='browse("+sizy+")' class='yellow'>Browse</a>");

到

$("#simply-popup").append("Unable to locate the subject you entered, please <a href='#' class='yellow browse'>Browse</a>");

为此

编写单独的代码

$('body').on('click', '.browse', function() {
    $('.browse-search-popup-link').click();
});

Answer 2

你不能在追加后调用该函数：

$("#simply-popup").append("Unable to locate the subject.....");
browse(sizy);// call it here.

或当您将其附加到元素中时，您可以调用点击：

$("#simply-popup").append("Unable to locate the subject.....");
$("#simply-popup a").click();

$(document.body).append('<a href="#" onclick="browse('+1+')">browse value is 1</a>');
$(document.body).find('a').click();

function browse(num){ $(document.body).find('p').html("<pre>"+num+"</pre>");}
