如何在一個文本中添加文本，並將其發佈到服務

Question

這是我的鏈接通過我的div可見

<a href="javascript:addMethod()">+ Create a new comment</a> 

和方法被調用它是如下

function addMethod() 
{ 

try { 


var div = document.getElementById('addComments'); 

div.style.visibility = "visible"; 

var textArea = document.getElementById('Textarea1'); 

textArea.style.visibility = "visible"; 

var mashupId = _settings.ratedObjectId; 

var tenantId = _settings.tenantId; 

var comments = null; 

var user = { "Id": 2007, 
"FirstName": "Ufone", 
"LastName": "", 
"EmailAddress": "ahmed.ali@vidizmo.com509" }; 

var ratingInfo = { 

"Id": 0, 

"TenantId": tenantId, 

"UserId": user.Id, 

"FirstName": user.FirstName, 

"LastName": user.LastName, 

"Rating": 0, 

"EmailAddress": user.EmailAddress, 

"Comments": comments, 

"RatedObjectTypeInfo": { "Id": 2 }, 

"RatingTypeInfo": { "Id": 1 }, 

"MashupRatingInfo": { "MashupMetaInfoId": mashupId }, 

"RatedObjectId": mashupId, 

"TotalCount": 0 

}; 

var url = "http://services.farooq.tv/RatingInfoManagementService/RatingInfoManagementService.svc/ajax/AddRating"; 

     $.ajax({ 
      type: "POST", 
      url: url, 
      data: JSON.stringify(ratingInfo), 
      contentType: "application/json", 
      timeout: 5000, 
      success: function (d) 
{ 

if (d.comments == true){ 

console.log(d); 

alert("Success"); 

}, 

error: function (xhr, ajaxOptions, thrownError) { 

console.log(xhr); 
      }  

}); 

} 

catch (err) 
{ 
alert(err); 
} 
} 

這是我的div和它裏面是一個文本區域和按鈕

<div id="addComments" align="center" style="width:300px; height:300px; visibility:hidden"> 
     <textarea id="Textarea1" style="width:300px; height:300px; visibility:hidden"> </textarea> 
    <button>Submit</button> 
    <button>Cancel</button> 

    </div> 

我想在文本區域添加文本，並將其保存在一個變量後提交按下按鈕

<button>Submit</button> 

，並在其中我想存儲文本區域的文本變量是

var comments = null;

這裏是您的解決方案http://jsfiddle.net/yangchenyun/erANK/

你可以用這條線設置textarea的

var comments = textArea.value = 'This is added text';
