$ .ajax（）给出[对象HTMLInputElement]而不是值

Question

我有一个$ .ajax（）请求正常工作，它调用3个ID。没有问题的唯一ID是名称ID。 clientId在控制台上记录的很好，但在表格上打印未定义。该URL正在打印表格和控制台上的[对象HTMLInputElement]，日志如下<input class="form-control no-border" type="text" id="redirectUrl" name="url" placeholder="http://stuffpage/redirect/?id=1" required="">。我想要打印我在输入中引入的url。

你能告诉我是什么问题吗？

$('#saveButton').on('click', function() { 
 

 
    var url = "http://stuffpage.com/redirect/redirect"; 
 

 
    var name = $('#name').val(); 
 
    console.log("name", name); 
 
    var clientId = $('#clientId').val(); 
 
    console.log("clicentId", clientId); 
 
    var redirecUrl = $('#redirectUrl').val(); 
 
    console.log("redirectUrl", redirectUrl); 
 

 
    var formData = new FormData(); 
 
    formData.append('name', name); 
 
    formData.append('client_id', clientId); 
 
    formData.append('url', redirectUrl); 
 
    console.log('test') 
 
    $.ajax({ 
 
    url: url + "/saveRedirect", 
 
    type: "POST", 
 
    dataType: "json", 
 
    data: formData, 
 
    contentType: false, 
 
    cache: false, 
 
    processData: false, 
 
    success: function(obj) { 
 
     var name, clientId, redirecUrl; 
 
     var rows = ''; 
 
     for (i = 0; i < obj.length; i++) { 
 
     rows += "<tr class='lightgrey'><th>" + obj[i].name + "</th><td>" + obj[i].clientId + "</td><td>" + obj[i].url + "</td><td><img id='editButton' class='col-md-2 edit nopad' src='http://stuffpage.com/redirect/public/img/edit.svg'><img class='col-md-2 link nopad float-right' src='http://stuffpage.com/redirect/public/img/copy.svg'></td></td></tr>"; 
 
     $("#table").append(rows); 
 
     console.log('sucess!'); 
 
     } 
 
    }, 
 
    error: function() { 
 
     console.log('error'); 
 
    } 
 
    }); 
 

 
});

Answer 1

看起来你有一个错字：

var redirecUrl = $('#redirectUrl').val();

应该

var redirectUrl = $('#redirectUrl').val();

Answer 2

您可以更换

var clientId = $('#clientId').val();

给你不使用`JSON.parse（OBJ）`对AJAX结果

var clientId = $('#clientId option:selected').val();

而且

var redirectUrl = $('#redirectUrl').val();
