    var RES = document.getElementById("Remarks").innerHTML;

<body>
<textarea id="Remarks" rows="5" na开发者_如何学JAVAme="Remarks" cols="79" style="font-family: Arial; font-size: 11px">please, accept my submit form.</textarea>

<br>
<img id="Submit" onclick ="return Data_Check();" border="0" src="submit.png" width="145" height="28">
</body>
<img
</html>

Here i facing the problem is,

When i submit "Remarks" textarea innerhtml to my "Data_Check.asp"

<%
RES = Request.Form("RES")
%>

and this remarks save in my sql database.( database field is "Remarks_text" and datatype is "text")

In the data base textarea data is read ("please, accept my submit form.") textarea data with out space.

like this please,acceptmysubmitform.

I need to save please, accept my submit form.

hoping your support

Try url encoding:

var RES = encodeURIComponent(document.getElementById("Remarks").value);

Change

document.getElementById("Remarks").innerHTML;

document.getElementById("Remarks").value;

I suspect spaces are not supported in URLs or HTTP headers, hence old URLs had %20 instead of a space. Modern browsers and servers now do this behind the scenes.

I found replacing spaces with %20 using formValues = formValues.replace(/ /gi,"%20"); prior to sending solved the problem.

Yes this is fixed!

Example :

var dataString = "textcontent="+test.replace(/ /gi,"%20");
