Jquery :: Detect Click On Disabled Submit Button stackoverflow.com

I have a form with a disabled (via javascript) submit button.

JQuery :: Enable / Disable Submit Button In IE7 stackoverflow.com

I am using the following code to disable the submit button $("input[type='submit']").attr("disabled", "disabled"); And this code to re-enable it: $("input[type='submit']").removeAttr("disabled"); It works fine on all browsers I've tried except Internet Explorer 7. IE7 will disable the button fine, but when it is re-enabled, the button still looks disabled. This button is enabled and clickable in spite of the cursor and gray color: (A colleague had the same trouble with IE8, but I could not reproduce it.) I have a workaround in place that does the job, but its ugly. I have two buttons, one disabled, one not. To start, I show the disabled one and hide the enabled button. $("input[type='submit']:first").css("display","inline"); //show disabled $("input[type='submit']:last").css("display","none"); //hide enabled ... <input name="Submit" type="submit" value=" Sign In " tabindex=3 disabled> <input name="Submit" type="submit" value=" Sign In " tabindex=3 > When my "if" conditions are met, I hide the disabled submit and show the enabled one. Is there a more elegant CSS or JQ based solution to this problem?

Cannot Enable XHTML Submit Input/button Which Is Disabled By Default? stackoverflow.com

I have this simple button in XHTML: <input type="submit" name="submit" value="Test" disabled="disabled" onmouseover="this.disabled=''" /> The problem is, no matter what I try, when I hover over the button, it won't re-enable from the disabled attribute it has. In XHTML, you are required to use disabled="disabled" which seems to completely break the option to enable/disable it with JavaScript. I've tried running this.disabled='', this.disabled=false, and even this.removeAttribute('disabled') but nothing seems to be capable of re-enabling the button. Weird thing is, if I remove the ='disabled' part of the attribute (making it invalid XHTML), the script enables the button just fine. Is this not possible without using invalid XHTML? Note: I'd really prefer to only use JavaScript for this specific example, not jQuery.

Toggle Disabling/Enabling Of 3 Dependent Input Textbox stackoverflow.com

I have this section where the user can define the filtering of a search result that he/she gets from the website. Price of Harddisk ($) Capacity of Harddisk (GB) Max. Cost per GB ($/GB) All 3 can be changed by the user. However since there are 2 independent variables defining 3 values, selecting the 3 filter values individually may yield 0 results. ie. $300 harddisk, 100GB & Lesser than $1/GB. The solution is to only allow the user to vary any 2 of the 3 filter options at any one time and automatically determining a value for the 3rd filter. Problem: I need a enabling/disabling behavior like this: When the user select filter #1 (price of harddisk = $100) then filter #2 (harddisk capacity = 100GB), when he selects a value for filter #3 ($5/GB), #1 will automatically be recalculated to $500. If he were to change filter #1 (harddisk cost = $200), then filter #2 will be changed to Capacity of Harddisk = $40 based on filter #1 and #3. How can I achieve this in jQuery/Javascript? My Thoughts: Something like a stack that contains only 2 values, in the order the filters are selected can be used. When the user select filter #1 then #2, the stack contains {1, 2} so filter #3 will be calculated using filter #1 and #2. When the user then select #3, 1 gets pushed off the stack, and 3 enters to result in {2,3} so filter #1 will be calculated using filter #2 and #3. However it seems like somehow something might go wrong with this method...

Validate Event www.vbforums.com

This is something weird I noticed the other day while testing our app. We have a tabstrip control (SSTab) and on each tab there is a frame which contains certain textbox and other controls.In two of the textboxes, I wanted to allow the user to edit the value only through the press of a command button. Otherwise the textboxes had to be disabled. So I coded the form in such a way that the textboxes are disabled at the beginning. In the Click event of the command button, I enable a textbox and allow the user to enter data into it. Since after data entry I again wish to disable the textbox, I trap the Validate event of the textbox and disable the textbox in this Validate event procedure.All was fine, until I clicked the button to edit the textbox, put some data into it and then clicked on another tab in the SSTab control. The other tab became visible, and then I returned to the earlier tab, and the textbox is still enabled!! That means the Validate event was not fired when I changed the tab.Here is the code:Code:Private Sub Form_Load()Text1.Enabled = FalseEnd SubPrivate Sub Text1_Validate(Cancel As Integer)Text1.Enabled = FalseEnd SubPrivate Sub Command1_Click()Text1.Enabled = TrueText1.SetFocusEnd SubI need a verification of my opinion that the Validate event is not fired when I click on another tab of the SSTab control on which the textbox is placed.Note that the Validate event does work with other controls, for e.g. when I move from Text1 to another control, say Text2, the Text1_Validate event is fired..

Till this point, no problem.Now I want that if the user enters Space (on the keyboard) in the TextBox, then also the CommandButton should remain disabled (or if it was enabled before Space was entered in the TextBox, it should get disabled). How would I do this? I tried this but it doesn't work:VB Code:[color=blue]Private Sub txtBox1_Change()    If (txtBox1.Text = "" Or vbKeySpace) Then        cmdButton1.Enabled = False    Else        cmdButton1.Enabled = True    End IfEnd Sub[/color] The above does disable the CommandButton if a Space is entered in the TextBox but at the same time, it remains disabled even if any other character on the keyboard is typed in the TextBox!Thanks,Arpan

Enabling / Disabling Button And Textbox Based On Status Of Checkbox stackoverflow.com

Override An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs? social.msdn.microsoft.com

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was selected). I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

Disabling Command Button www.access-programmers.co.uk

Im new to this, and a beginner at database design, but I am currently stuck on disabling a command button. Basically what happens is the form is loaded and there are two buttons (save and undo) both disabled: Private Sub Form_Current() Me!cmdSaveAddAd.Enabled = False Me!cmdCancelAddNewAd.Enabled = False End Sub once a text box has been filled in the next occurance happens: Private Sub Form_Dirty(Cancel As Integer) Me!cmdCancelAddNewAd.Enabled = True Me!cmdSaveAddAd.Enabled = True End Sub which enables both buttons. but the problem is when a user clicks the undo button i want both buttons to be disabled again, i cannot get the undo button disabled, the save button was easy enough: Private Sub cmdCancelAddNewAd_Click() DoCmd.RunCommand acCmdUndo Me!cmdSaveAddAd.Enabled = False End Sub but if i put (Me!cmdCancelAddNewAd.Enabled = false) i get an error message saying 'you cannot disable a control that is in focus'.
