Question

我使用ajax用于laravel当前项目，我尝试使用ajax传递textbox的值，但每次都传递R，即使我使用ajax传递了错误的变量。我的代码如下

 <div class="form-group">
    <label for="">Total Amount</label>
    <input type="text" class="form-control" id="total_amount" value="123" name="total">
 </div>

javascript代码

    $("#id_label_multiple").on('change', function () {
        var list = $("#id_label_multiple").val();
        var total = $("#total_amount").val();
        console.log()
        $.ajax({
            url: "{{ action('hkcontroller@getTotal') }}",
            data: {
                lists: list, total: total, "_token": "{{ csrf_token() }}"
            },
            type: "POST",
            success: function (data) {
                $('#msg').html('Received ' + data + ' stones form exporter successfully!')
                console.log(data);
            }
        });
    });

laravel方法

public function getTotal(Request $request)
{
    $list = @$request['lists'];
    $total = @request['total'];
    return $total;
}

varibale list工作正常但total总是返回值R，当它第一次打印log时，它在控制台中打印正确的值，但第二次在{ {1}} ajax的功能始终打印success。在哪里我弄错了？

Answer 1

改变这个：

$total = @request['total'];

到此：

$total = @$request['total'];
          ^

Answer 2

尝试如下：

$("#id_label_multiple").on('change', function () {
        var list = $("#id_label_multiple").val();
        var total = $("#total_amount").val();
        console.log()
        $.ajax({
            url: "{{ action('hkcontroller@getTotal') }}",
            data: "lists="+list+"&total="+total+"&_token={{ csrf_token()}}",
            type: "POST",
            success: function (data) {
                $('#msg').html('Received ' + data + ' stones form exporter successfully!')
                console.log(data);
            }
        });
    });

ajax得到错误的价值
