Question

我目前遇到了一些问题，基本上我创建了一些populateModal（）函数来用相应的html填充模态容器。它适用于populateModal3和populateModal4（功能相同但具有不同的url值）。

ajax返回json中的数据，并且在其他两个populateModal函数中完全正常。

这是函数的片段

$.ajax({
                url: "transaction/get_transaction",
                dataType: 'json'
            }).done(function(data){
                $('#transModalContainerDel, #transModalContainerEdit').empty();
                console.log(data);
                for (var i = 0; i < data.length; i++)
                {                   
                    console.log('id data: ' + data[i].id);
                    theDelTransModal += 'id modal: ' + data[i].id;
                    //theDelTransModal += '<div id="transModalDel' + data[i].id + '" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="deleteTransaction" aria-hidden="true">';
                    //theDelTransModal += '<div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h3 id="myModalLabel">Delete transaction?</h3></div>';
                    //theDelTransModal += '<div class="modal-body"><p>Are you sure you want to delete this transaction? Note that you can\'t undo this action.</p></div>';
                    //theDelTransModal += '<div class="modal-footer"><a class="btn" data-dismiss="modal" aria-hidden="true">Cancel</a><a href="transaction/delete_transaction/' + data[i].id + '" class="btn btn-primary" id="delete-trans" data-dismiss="modal">Delete</a></div>';
                    //theDelTransModal += '</div>';
                    //$('#transModalContainerDel').append(theDelTransModal);
                    console.log(theDelTransModal);
                }       
            });

从上面的代码中可以看出，返回的数据是正确的json格式。但我尝试记录的id返回此值。

id data: 21 
id modal: 21 
id data: 22 
id modal: 21id modal: 22

我不确定出了什么问题，因为这个功能非常适合其他网址。

提前致谢

这只是因为字符串加入

theDelTransModal += 'id modal: ' + data[i].id;

等于：

theDelTransModal = theDelTransModal+ 'id modal: ' + data[i].id;

删除加即可。

使用ajax成功方法

$.ajax({
                url: "transaction/get_transaction",
                dataType: 'json',
                success:function(data){

$('#transModalContainerDel, #transModalContainerEdit').empty();
                console.log(data);
                for (var i = 0; i < data.length; i++)
                {                   
                    console.log('id data: ' + data[i].id);
                    theDelTransModal += 'id modal: ' + data[i].id;
                    //theDelTransModal += '<div id="transModalDel' + data[i].id + '" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="deleteTransaction" aria-hidden="true">';
                    //theDelTransModal += '<div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h3 id="myModalLabel">Delete transaction?</h3></div>';
                    //theDelTransModal += '<div class="modal-body"><p>Are you sure you want to delete this transaction? Note that you can\'t undo this action.</p></div>';
                    //theDelTransModal += '<div class="modal-footer"><a class="btn" data-dismiss="modal" aria-hidden="true">Cancel</a><a href="transaction/delete_transaction/' + data[i].id + '" class="btn btn-primary" id="delete-trans" data-dismiss="modal">Delete</a></div>';
                    //theDelTransModal += '</div>';
                    //$('#transModalContainerDel').append(theDelTransModal);
                    console.log(theDelTransModal);
                }       
}
            });
