How to insert item in Sharepoint list using javascript and Sharepoint web services

We can store insert items in Sharepoint items using many ways like using Sharepoint object model etc. But I need to insert items with Javascript.

I googled lot but didn't get any useful infomation, only Jan tielens' Blog has some infomation which showing list data on page using jQuery.

Finally I created the solution which stores the text box value in the Sharepoint list on button click. Following steps will show step by step information.

• Create the blank web part page in your sharepoint site.
• Browse this web part page
• Edit page by clicking on site action -> Edit page
• In any web part zone, click on 'Add a web part' then add 'Form Web part', Modify this web part.
• Click on source editor button, it will open new window to add your content.
• I added a HTML textarea and button with simple javascript which will store textarea value in given sharepoint list.
• (Before that create new custom list with any name as you wish. I created with name 'Suggestions'
• On source editor, copy and paste following code
• 
  
  

  <script type="text/javascript">     function addSuggestion(SuggestionText) {         var xmldoc;         var batch;         var FeedbackHTTP;         var ListName = 'Suggestions';         //The batch variable builds up the XML that we are going to submit to the SharePoint list via the SharePoint web service         batch = "<batch><method id="'1'" cmd="'New'"><field name="'Title'">" + SuggestionText + "</field></method></batch>";         xmldoc = '<?xml version="1.0" encoding="utf-8"?><soap:envelope xsi="http://www.w3.org/2001/XMLSchema-instance" xsd="http://www.w3.org/2001/XMLSchema" soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:body><updatelistitems xmlns="http://schemas.microsoft.com/sharepoint/soap/">'         xmldoc = xmldoc + '<listname>' + ListName + '</listname>';         xmldoc = xmldoc + '<updates>' + batch + '</updates></updatelistitems></soap:Body></soap:Envelope>';         FeedbackHTTP = new ActiveXObject("MSXML2.XMLHTTP.3.0");         FeedbackHTTP.Open("POST", "http://YourSiteURL/_vti_bin/Lists.asmx?op=UpdateListItems", true);         FeedbackHTTP.setRequestHeader("Content-Type", "text/xml; charset=utf-8");         FeedbackHTTP.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/sharepoint/soap/UpdateListItems");         FeedbackHTTP.Send(xmldoc);         alert("Thank you! your suggestion has been submitted successfully.");     } </script> <textarea cols="15" id="txtSuggetion" rows="6"></textarea> <input id="myButton" onclick="javascript:addSuggestion(txtSuggetion.value);txtSuggetion.value = '';" type="button" value="Submit" />

  
  
  
  
  
• (Note: Change YourSiteURL with your site name)

• click on save button.
• this will give you text area, insert any comment in text area then click on Submit button.
• Now check your 'Suggestions' list. New item store with textarea value as in title.
