【问题描述】：

我的 Laravel 代码如下

public function validateRegisterToBidForm(Request $request){

    $validationArray = $this->getValidationArray();

    $this->validate($request, $validationArray);
    return response()->json();

}//validateRegisterToBidForm

上面的输出在 Ajax 中接收如果出现错误，那么我将上面的输出字符串化并获得以下 json

{"readyState":4,"responseText":"{\"fname\":[\"This field is missing or incorrect.\"],\"lname\":[\"This field is missing or incorrect.\"],\"email\":[\"This field is missing or incorrect\"],\"password\":[\"This field is missing or incorrect.\"],\"adr1\":[\"This field is missing or incorrect.\"],\"city\":[\"This field is missing or incorrect.\"],\"state\":[\"This field is missing or incorrect.\"],\"phone\":[\"This field is missing or incorrect.\"],\"primary_phone\":[\"This field is missing or incorrect.\"],\"pass_dri_license\":[\"This field is missing or incorrect.\"],\"card_type\":[\"This field is missing or incorrect.\"],\"cardno\":[\"This field is missing or incorrect\"],\"cvv\":[\"This field is missing or incorrect.\"],\"fname_b\":[\"This field is missing or incorrect.\"],\"lname_b\":[\"This field is missing or incorrect.\"],\"email_b\":[\"This field is missing or incorrect.\"],\"adr1_b\":[\"This field is missing or incorrect.\"],\"city_b\":[\"This field is missing or incorrect.\"],\"state_b\":[\"This field is missing or incorrect.\"],\"phone_b\":[\"This field is missing or incorrect.\"],\"primary_phone_b\":[\"This field is missing or incorrect.\"]}","status":422,"statusText":"Unprocessable Entity"}

如何提取值？正确的方法是什么？

【解决方案1】：

你可以有这样的电话：

 $.ajax({
        type: "POST",
        url: "the/url",
        data: {the: data},
        success: function (myresponse) {
            console.log(myresponse);
        },
        error: function(xhr, status, error) {
            var err = JSON.parse(xhr.responseText);
            console.log(err);
        }
    });

实际上，这就是我使用的：即JSON.parse();，因此您可以使用err 变量选择每个字段，例如err.fname

我希望这会有所帮助:)
