jquery onclick模式弹出窗口中的按钮更改当前td的值

Question

使用 bootstrap 和 jquery，我创建了与模式弹出窗口链接的表。在表格中，我有两个操作图标

1. 激活
2. 停用

目前，点击表格中的激活图标，弹出窗口会显示当前行的值以及激活按钮，我需要OnClick此弹出窗口中的激活按钮需要将当前 td 中的激活图标更改为停用图标。就像对 De-activate 图标一样需要做。请帮我找出来。

下面是代码。

<div class="table-responsive">
    <table class="table table-bordered table-striped table-hover">
        <thead>
            <tr>
                <th>Name</th>
                <th>Username</th>
                <th>Action</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td><a href="#" data-toggle="modal" data-target="#usrdetails"><span class="lsusrfname">Jayashree</span></a></td>
                <td><span class="lsusrlname">Gopalan</span></td>
                <td align=center>
                    <a href="#" data-toggle="modal" data-target="#usract"><span class="usrin glyphicon glyphicon-ok" title="Activate"> </span></a>
                </td>

            </tr>
            <tr>
                <td><a href="#" data-toggle="modal" data-target="#usrdetails"><span class="lsusrfname">Siva</span></a></td>
                <td><span class="lsusrlname">Prasad</span></td>
                <td align=center>
                    <a href="#" data-toggle="modal" data-target="#usrdeact"><span class="usrrm glyphicon glyphicon-remove" title="De-Activate"> </span></a>
                </td>
            </tr>
        </tbody>
    </table>

请帮我找出来

Answer 1

如果您需要更改的只是前端的东西并且您不太关心后端，那么您可以使用 jQuery 根据需要添加和删除类。 使用你的小提琴：

/* Click the tick button and add a class of current */
$('.usrin').each(function(){
    $(this).on('click' , function(){
        $(this).addClass('current');
  });
});
/* Click the x button and add a class of current */
$('.usrrm').each(function(){
    $(this).on('click' , function(){
        $(this).addClass('current');
  });
});
/* Click the activate button and change the classes of the tick or x */
$('#actusr').on('click' , function(){
    var current = $('.table-responsive').find('.current');
  current.toggleClass('usrin glyphicon-ok usrrm glyphicon-remove');
});
/* Click the de-activate button and change the classes of the tick or x */
$('#de_actusr').on('click' , function(){
    var current = $('.table-responsive').find('.current');
  current.toggleClass('usrin glyphicon-ok usrrm glyphicon-remove');
})
/* Click the window close button and remove the current class */
$('.close').on('click' , function(){
    var current = $('.table-responsive').find('.current');
  current.removeClass('current');
});

我已经对它进行了广泛的评论，但它似乎可以满足您的需求。首先，当单击字形时，我们需要“标记”触发模式的元素，无论是激活还是停用。然后，如果模式被关闭，我们需要删除该书签。如果用户点击了激活/停用按钮，我们需要做很多事情（可能包括您的后端处理）：我们需要删除该书签，更新字形类，重定向目标模式，并更改工具提示文本。在下面查看它的工作方式，或作为 fiddle。

同样，我的代码应该非常清楚地记录在案。祝你好运！

$(".usrrm, .usrin").click(function() {
  // Mark the element that triggered the modals. we'll need this later.
  $(this).parent().addClass("currently-active-el");
  
  // Populate the modal fields.
  var tdusrname = $(this).parents("tr").children("td:first").text();
  $(".fname").val(tdusrname);

  var tdlname = $(this).parents("tr").children("td:nth-child(2)").text();
  $(".lname").val(tdlname);
});

/*****
 * #actusr.click() - we are activating this user. At this point,
 *    we need to go back to that element that triggered the modal,
 *    and remove its flagging class. We have a few other things we
 *    need to do: first, redirect the modal target from the active
 *    modal to the deactive modal, and change the icons for the span.

$("#actusr").click(function() {
  $(".currently-active-el")
    .attr("data-target", "#usrdeact")           // redirect the target modal,
    .removeClass("currently-active-el").        // remove the placeholder
  find("span")
    .removeClass('usrin glyphicon-ok') // toggle the glyph class
    .addClass('usrrm glyphicon-remove')
    .prop("title", "Deactivate")                // change the tooltip text

});

/*****

 *    we need to go back to that element that triggered the modal,
 *    and remove its flagging class. We have a few other things we

$("#de_actusr").click(function(evt) {
