Question

我正在尝试将文件加载到已存在内容的div中。但是当我加载文件时，div中的内容将被删除。我怎么能阻止这个？谁可以帮助我？代码如下所示。

jQuery的：

<script type="text/javascript">
$(document).ready(function() {
    $('.type_of_connection').change(function() {

        var selected_value = $(this).val();
        $('.content').not("#" + selected_value).hide();
        $("#" + selected_value).fadeIn();

        $('.supercustomer').change(function() {
            var supercustomer_id = $(this).val();   

            $("#" + selected_value).load('show_switch.php', {supercustomer_id: supercustomer_id});
            ;
        });
    });
});
</script>

HTML

    <div class="top_child">

是.load()会覆盖当前div中可用于从其他页面动态加载内容的旧内容。要解决此问题而不是使用.load()，您可以使用$.get()：

$(document).ready(function() {
    var selected_value = ''; // <-----make a global var here
    $('.type_of_connection').change(function() {
        selected_value = $(this).val(); // <------update the value here
        $('.content').not("#" + selected_value).hide();
        $("#" + selected_value).fadeIn();
    });

    $('.supercustomer').change(function() {
      var supercustomer_id = $(this).val();
      $.get('show_switch.php', {supercustomer_id: supercustomer_id}, function(html){
          $("#" + selected_value).append(html); //<---append the html here.
      }, "html");
    });
});

将文件加载到div而不删除内容
