Web Forms :: Get The Value Of Textbox Through Javascript?
Feb 11, 2010
I am trying to get the value of a textbox through javascript. In VS 2005, I've created a Textbox with id "SearchBox" and a Button with id "Submit". In the Click client events of "Submit", I have the following function,
[Code]....
But I am getting the following error. "Object Required".
I'm trying to use a javascript Date and Time calendar in my Insert and Edit templates in a Detailsview that is bound to SQL Fields. The reason I am trying the javascript date time selector is that I need to have the date and time, the asp.net one is just the date part.
I tried using it with an asp:textbox on just a plain aspx page and it works like a charm, however when I add it to the detailsview i keep on getting the "Error: Object required" am I missing a step here? That and seeing as I'm using a site master page where exactly do I put the:
I created a page with several controls (ddl, tbx) that I use for filtering a Gridview. I created a javascript function that runs on the OnClientClick Event of an <asp:button to set the value of an <asp:TextBox to today and a Selected Value in a ddl.
function setMyToday() { var tbxToday = document.getElementById('ctl00_cntPage_tbxToday'); var tbxUID = document.getElementById('ctl00_cntPage_tbxUserID'); var ddlPV = document.getElementById('ctl00_cntPage_ddlProvider'); tbxToday.value = makeToday(); ddlPV.value = tbxUID.value; }
The button submits the page and returns some records in a Gridview. I can see the value in the tbxToday when the button is clicked and the row in the drop down list, but when the page is posted,the value in the text bos is lost and as a result is not used to filter the records. However the value in the ddlProvider is maintained.
i create a number of dynamic textbox in my page using server control but these control call the javascript function , so , now i want to validate the each dynamic text for validation of name server
pass name of the textbox Control to javascript function
[Code]....
<script type="text/javascript" language="javascript"> var sum = 3; var textboxObj,ObjName; function validate(textboxObj,ObjName) { alert('Hello'); var arrayOfObjects = document.getElementsByName(ObjName); alert(arrayOfObjects.length); for (var i = 0; I < arrayOfObjects.length;i++) { alert('Inside for loop');............................
I am trying to make ONE thing work. The form currently have TWO Textboxes and ONE CustomValidator(connected to the first textbox). I simply want once I enter less than 4 characters in the first Textbox and tab out to the second Textbox and if Javascript is DISABLED then the server side code should stop me. I can achieve what I am trying to do if I use a button but I need to do it in the fashion I am trying decribing because if I have for example 20 textboxes on the form I want the user to see after each data entry that his validation was successful or not. Here is a sample of my code.
I have a custom user control that contains within it a repeater control. Inside this repeater I programmatically add another custom user control, which contains a text box and a custom validator. This final custom user control can be added any number of times depending on the application's logic. All of this is part of a wizard step. When the user completes the step, if any of the data added to the text boxes is incorrect the validator gets fired on post back. However, because I can have any number of these controls added to the repeater, the user has to scroll down to see any of the incorrectly completed boxes.
Due to the controls being added dynamically it is not possible to use a validation summary control - I have tried!!! Therefore, is there away I can use JavaScript to position a cursor or to jump to each incorrectly completed textbox without the user needing to scroll down the page? For example, if there are 10 textboxes, and textboxes 8 and 9 have numbers inside them inside strings, then the JavaScript should jump textbox 9.
I have a gridview and template field (textbox) control. on GridView_RowDataBound I want to find the control and pass the control id to a javascript which will set datepicker on that textbox here is how I am doing but its not working.
I have a javascript in a .js file to pad zeros to the left of a number in a textbox. I have a textbox on a search screen for which this function works just fine. But when I tried to apply the same function to a textbox in a repeater on the data entry screen, it just does nothing. I get no errors, but it doesn't pad the field when I leave it.avascript function:
function pad(tb, length) { var str = '' + tb.value;
I am having my girdivew as follows.URL....After selecting customer it will be as follows. URL...I would like to display the sum in the label available on the from.This is what I have written to display Amount in the amount textbox
<script type="text/javascript"> function multiplication(txtQuantity, txtRate, txtAmount) { var weight = document.getElementById(txtQuantity).value; var rate = document.getElementById(txtRate).value; document.getElementById(txtAmount).value = weight * rate;
I have the following code which sets the focus of the textbox, but I now also want th text in the textbox to be highlighted, but without the use of JavaScript. I have tried using JavaScript but cannot get it too work, is there any other way to do it?
Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing GridView1.EditIndex = e.NewEditIndex BindData() GridView1.Rows(e.NewEditIndex).FindControl("txtTargetAmount").Focus()
suppose i have gridview in which i have multiple empty Textbox ; In this i want to use autocomplete property of jquery in a particular textbox ; so fro this i have to firstget the id of this textbox .so how can we get the id of this textbox that is inside a gridview
I want to get this box's current value in javascript. How can I access this element? If it was a normal html text box, with id="txtQuantity", then I could access it using "document.getElementById("txtQuantity")". But how can I access ASP.NET text box in javascript?
