Update The Value Of An Element That Isn't A Form Input?
Apr 7, 2009
I'm using Javascript to create some dynamic content on my website. Basically it's looping through some values and updating an input field with the values.
What I'm wondering is, do I have to do this using a form and an input field? Is there a way I can get Javascript to update the content inside a DIV for example?
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 need to make a change to a web page that has lots of JQuery things in it, it appears. Not knowing anything about the actual use of JQuery, however, while I will start looking at the doc, can someone help me with what to look for in a 4000+ line file to find out where the value is being set for the hidden field. I have been unable to identify this. There appears to be no onChange or onSubmit JavaScript call. I have been given this file with the need to figure this out right away, with a very tight timeline to make many changes, so this one item can't take the time required to start learning the whole of JQuery before I can make a change.
I found this forum while running out of ideas and being extremely desperate to fixing a probably small javascript error in a script. the script is supposed to open a small form window that allows the user to input an email address and update it to proceed. the form item is initially unchecked, but as the user clicks it and enter his email address, it updates the value of the email address and the box becomes "checkable". the problem is that with both IE and firefox, the box doesn't close again, doesn't get checkable and basically doesn't work. in the firefox debugging console, I found the following error:

The part responsible in the javascript for this section is:

And the html code that is supposed to pop up the box is:
I created this test routine to return the form containing a certain input element:
function GetElementForm(element) { // Return the form that contains element.
varmyElement = element;
while (myElement) { myElement = myElement.parentNode; if (myElement) { var sTagName = myElement.tagName; if (sTagName) { if (sTagName.toLowerCase() == "form") { break; }}}} return myElement;}
This seems to work for "well formed" HTML, but fails for example, when a form is defined within a table.
im trying to post each input element in my form. The elements are generated with a click function. So if there are 2 elements i want to post the values of both to a php script. This is what ive tried so far but it doesnt appear to work.
I have two input fields and I want the second updated every time I change a value in the first. I wrote this function but it doesn't work until the first element lost focus (for example I clic anywhere or press TAB button)
I've got a select box that, when you choose any option besides #5, it changes the value of a related input box from 0 to 1. This works great except when I hide() the div that wraps this input box. My overall goal is to have the input (and surrounding div) hidden via hide(), and then update this input box when a select is changed.
Here is my code: $(document).ready(function(){ $("div#edit-qty-56-wrapper").hide(); function enterQty() { var attrValue = $( "select#edit-attributes-56-1" ).val(); if (attrValue !== '5') { $("input#edit-qty-56").val('1'); } else { $("input#edit-qty-56").val('0'); }} $("select#edit-attributes-56-1" ).change(enterQty); enterQty(); });
I've got a slider in jquery and I want it to populate an input box with a value as it is slid. I also want the user to be able to enter a value into the input box and for the slider handle to move to the appropriate position.
I've found an example of the bare-bones slider in the jquery docs and some basic documentation, but I've no idea how to get it to do what I need, and can't find any simple, fully featured examples anywhere which do what I need.
i have one task in which i have to update the information on DIV on one of the webpage which will run on another system which can be any client system. is it possible to update the information of the web page in real time so that if some client is watching the other web page at that time, he will see the latest content.
i dont want to create server side scripting and logic for this as this is very small content. anyone with some idea about this?
i have jquery code which highlights <p> elements with specific class. everything works ok but if i update elemet with content including tag <p>, highlighting doesnt work.
When user inputs text to "text1" I want to reflect changes in "text2". When value is changed in "text2" I want to change value in "text3". So I handle keyup event in "text1" and then successfully update "text2". But which event need to be handled when value of "text2" is changed?
Important remarks:1. I don't want to update "text3" from "text1".keyup event. My goal is to handle some event when value in "text2" is changed(may be by user or may be by code)2. "text3" needs to be changed immediately after "text2".value changed
I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.
Is this possible with JQuery? I have the following code which I think Should do this, but it's not working :/These are two different functions which I've been testing, and the html element is supposed to create a dropdown list via some PHP which will have the option "Other" within it. Unfortunately, I have no idea exactly how to turn "Other" into a text box when the user clicks, and I've been spending a lot of time on this already.
so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
For instance, Box A has a blank entry and I enter in 5. Box B I enter in 6 so in Box C it should automatically give me 11 (if the code I put in is to add box A and B). Then in Box D I put in 3 (say to subtract from A and B combined) so then Box C adjusts to give me 8.
Don't worry about the math as that's all taken care of it, I just need to be able to know how to update on the fly like this.
I have a pageA containing a form the user my fill in partially. All data is stored into cookies. He follows a link to pageB that contains some of pageA.form inputs. If he adds or change form data cookies are instantly updated. What I need is if the user goes back (back browser button) to pageA, the form here is updated from updated cookies. Only Firefox 3 does the job without extra code. Ive tried all sort of things I found on the web with Opera 10, Chrome and Safari 3.
I'm making a survey where every question has a numeric value assigned to it, and as the user clicks on a checkmark button to approve (or uncheck to disapprove) the values add or subtract to give a total at the bottom of the page.
Basically, it's a spreadsheet but with fixed values for each row instead of being able to type them in.
I can do this easily with php, but only if the user clicks the submit button. I was hoping to find a way to do this real-time.
I'm not looking for someone to do this for me, but can someone point me in the right direction of a tutorial or something that is similar so I can build this into my program?
I have a page with 2 forms on, namely form1 and form2!!
In form1 there is a listbox with a drop down of IDs. Now if the user selects a different ID in that list, form2 hidden variable (qualstatus) needs to be updated with the new ID which was selected in form1. I have tried the following.
function changequal() { document.form2.qualstatus.value = document.form1.qualstatus.value }
Is there a way to change a javascript's output on a website without directly manipulating the source code? Just by entering some info in a form, then hitting submit. Then it automatically changes the content of a website.
What I want to happen is to change some text (specifically a news ticker) on my javascript, located in between the head tags, just by inputting new information on a form which automatically replaces the old one.
I am using Form in a PHP Code - which post the results to another external - application, and i would like to save some recordes in DB (when someone use the submit button) before moving on to the external-app. how could i do this in a javascript or is it possible?
I'm doing an ajax call to a remote php file... it returns a value fine, and even enters a value into a text field on my form. The problem is, right after the function call to the ajax function, I do an alert of what the field value is, and it doesn't recognize the field value has been changed. Two caveats:
1 - It will recognize the last call's change (if I run it a 2nd time, it'll see the 1st call changes) onBlur="ajaxCall(document.form1);alert(document.form1.ajax Field.value);">
2 - It'll recognize the current call's change if I set a 2 second timeout onBlur="ajaxCall(document.form1);setTimeout('checkFields(d ocument.form1)',2000);">
It seems, although I can see the text field getting updated, programmatically speaking, it isn't reflecting it until everything is done... including any alerts and such.
It's weird seeing the empty alert popup, when I can see the value in the text field underneath it.
