javascript - 单击 div 时显示表单

Question

我正在从 JSON feed 生成条目列表。我想单击一个 div 并调出编辑模式。我在从 click 事件获取 relatedTarget 时遇到一些问题。它返回为未定义。

还有其他方法将数据传递到模式吗？

$.getJSON('api/v1/module', function(data){
    $.each(data, function(i, learning) {
        var $div = $('<div>')
        .append(
            $('<p>').text(learning.title),
            $('<p>').text(learning.lastupdated)
        )
        .addClass('panel panel-default')
        .attr('data-title', learning.title)
        .appendTo('.module-list')
        .on('click', function(){
            $('#edit-module').modal({
                show: true
            })
        })
    });
})

$('#edit-module').on('show.bs.modal', function (event) {
    var button = $(event.relatedTarget) // Button that triggered the modal
    var recipient = button.data('title') // Extract info from data-* attributes
      // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
      // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
    var modal = $(this)
    modal.find('.modal-body input').val(recipient)

    console.log( event.relatedTarget )
    console.log( event )
    console.log( button )
    console.log( JSON.stringify(button) )
})

来自Boostrap docs :

If caused by a click, the clicked element is available as the relatedTarget property of the event.

但是这里的显示是由modal()引起的，而不是初始点击。

要按照文档中的描述让点击触发显示，您需要使用 Boostrap 的 data-toggle 调用模式。添加这些数据属性，并删除您的 .on() 处理程序:

$.getJSON('api/v1/module', function(data){
    $.each(data, function(i, learning) {
        var $div = $('<div>')
        ...
        .attr('data-title', learning.title)
        .attr("data-toggle", "modal")
        .attr("data-target", "#edit-module")
        .appendTo('.module-list')
    });
})
