I am displaying a modal dialog using jQuery. This dialog has a textarea
control on it. But while submitting this dialog, the value of this textarea
is not recognized by jQuery for some reason: it always comes blank.
This works perfectly in other browsers. I put alert to display the value but it looks blank. Can anybody help me in this regards?
Controls:
<input type="text" id="txtGroupName"/>
<textarea rows="3" cols="30" id="txtDescription"></textarea>
jQuery code which used this value:
var postData = new Object();
postData.GroupName = $('#txtGroupName').val();
postData.Description = $('#txtDescription').val();
$('#txtDescription').val()
comes blank but $('#txtGroupName').val()
is read correctly as it is a input field.
One more finding about this issue:
When I put alert in my update function after populating the control value on page load, this alert displays the existing value properly. But it displays only existing value. It does not display the edited value after submitting the modal box.
We can get the value of textarea in jQuery with the help of val() method . The val() method is used to get the values from the elements such as textarea, input and select. This method simply returns or sets the value attribute of the selected elements and is mostly used with the form elements.
jQuery val() Method The val() method returns or sets the value attribute of the selected elements. When used to return value: This method returns the value of the value attribute of the FIRST matched element.
I fix this using this in textarea
$("#descripcion").keydown(function(){
$("#descripcion").css("display","block");
});
put at end of script. I am sorry for my english
val() and text() in jquery works correctly, but after setting value of textarea you need to rerender textarea, you can do this setting css property in such way
if ($.browser.opera)
$('textarea').val(someText).css({display:block});
else
$('textarea').val(someText);
Hello from Russia. Sorry for my english =)
Have you tried .attr("text")
or .attr("value")
? I'm unable to test this but this would seem logical to me.
If it doesn't then let me know and I'll remove this answer.
