GetElementById("ta") Does Not Update With Change In <textarea Id=ta> And Visa Versa
Mar 25, 2010
While this works in IE I just cant get it to work in Firefox. Any changes in the textarea are not passed on when you click the 'doit' button and the 'addTxt' button only works once. How can I get the 'doit' button to display the text entered into the textarea?
How would i change back to the default length of textarea?
I have this comment area that after clicking submit i will append the new comment in the list of comments through ajax... i got one problem though, everything is working perfectly well except for the textarea that won't change back to it's default size...
EXAMPLE:
The problem is that the textareawon't change back to it's default size // let's say that the default size is rows=3
I'm trying to update a textarea's value with Javascript. The code is similar to:
console.warn("Before set, value is " + document.getElementById('myTextArea').value); document.getElementById('myTextArea').value = 'OMGWTFBBQ'; console.warn("After set, value is " + document.getElementById('myTextArea').value);
Although the Firefox and Chrome consoles show that the value property is updated, this is not reflected in the page itself.The specific function is invoked from an onfocus handler of another element. The textarea itself is lazily initialised from the same method, by using:
var messageText = document.createElement('textarea'); messageText.id = 'myTextArea'; someParent.appendChild(messageText);
Obviously if I use the console rather than let the script run it does work.
I have an idea for a little script.....I'm just stuck on one little part: When a user changes the value in a input or textarea box, I want it to change the value of a certain hidden input tag too.
Here's what I have so far:
function getNewValue(inputhidden, textinput) { var data = document.getElementById(inputhidden); var text = document.getElementById(textinput); data.value = text.value;
I'm using a text area to display textual updates to a user from the server. I'm inserting the text at the bottom of the textarea and need to set the scrollbar to the bottom of the textarea after every update. The problem is that the onChange event only fires if the user actually changes something in the text area, not if it is changed by an ajax update.Does anyone know of a way to detect if there has been an update to a textarea that was NOT triggered by a user?
how to change getElementById to a 'class' equivalent? This script works, however, I need to use it 3 times on a page but it uses ID instead of class. The two IDs that I wrap around the images that would scroll are: #marqueecontainer and #vmarquee.
I've done this so many times before but I can't seem to get it working!! All I'm trying to do is in the JavaScript at the top change a span tag to whatever the current window location is but it doesn't work!
I'm trying to implement a simple chatting website. For now what the code does is checking every 10 seconds if there are new posts stored in the database (newer than the last check, 10 seconds ago). Is there a more efficient way than doing this with a timer??? for example, is there some kind of event listener attached to the server that would notify the client whenever the db is updated?
I am current building an information database for the company I work at...basically just a place for employees to get information and answers from. It is all hosted on a local server and I can only use javascript, html, and css. I've got everything made there is just one thing i want to add to it. Basically an "alerts and updates" page that only some people can edit without having to know html so if im not there they can post important updates. No computers have access to the internet so I did try some rich text editors but none of them worked. The layout I'm going for is kind of like this.
Alerts and Updates Click on links to show updates: update 1 * update 2 * update 3 * update 4 Stuff goes in the update [edit button] You click edit it prompts you to login, bring up something to edit the text in that specific update you hit submit and it changes the info that was on there. The update links are linked to a script I wrote that just display the info below so when the page loads you see whats in update 1 then you click update and it changes the content to the next one.
It could be a two function javascript or two separate javascripts, I am not that particular as long as it does what I need it to do. The way I would like to see it work is you type the number you have into a field, and press a button to convert it. If it was a two function javascript you would have to select the conversion type you want do first.
I am trying to detect whether a user entered text in a textarea or hit the delete/backspace button (thus, erasing something). Once that is detected, I would like to set "var bSaveRequired = true;". It would be great if this function worked cross-browser -- IE 6.0 and Firefox.
i wants to change one input to texarea when i select one from radio, plz any suggestion how i would do that?so when i click inputtext radio name"other" will become a textrea rather then input type text.
I've been trying to change the text in a textarea element to no avail. I'm using the following to change the text:
$(inlineEditor.CurrentEditCollection).find('#resource_description').each(function(){ this.val(vals.value); }); vals.value contains the text. The Textarea element is in a TD in a TR that is contained in inlineEditor.CurrentEditCollection
The selector seems to find the element just fine but the text will not change.
I would like to be able to change the "wrap" attribute for a textarea with javascript. That is unless you can provide a cross browser solution in css2, giving me the ability to just modify the css attributes.
I want a set up some type of array/ IF statement within a textarea.
This is what i want it to do...
If textarea text = "[example]" then change colour of font #383838
I need it as a basic validation method to ensure the user has typed in the correct text. for example if the member uses { in stead of [ it will not turn a different colour and the user ill no they have not typed it in correct.
I presumed there would be some JQuery code out there that would enable this but I can't find it. ( or even know what search term to use )
I have a Java form where I need to be able to switch a drop down with a text box using Javascript. The change would be made depending on the radio button choice the user makes. The drop down is the default form element and radio button A is checked by default. So when the user clicks radio button B the text box should appear and if they change their mind and select radio button A the drop down should come back.
Whats making this a little tricky is that I'm doing my form validation using Java via the form element name. So these two will have the same name. I need for the drop down to be switched off/disabled if they have radio button B and vice versa. Is all this doable using javascript?
