Change The Value Of Several Textfields With 1 Buttonclick
Nov 4, 2011
I have a problem with buttons + textfields. I want to change the value/text of several textfields at once, if i click on a button. If i click again, i want to clean the textfields again.
So i made following javascript-function, which should be startet, when i click on the button.
variable-declaration + button:
HTML Code:
textfields:
HTML Code:
JS-function:
Code:
When i use (f.e.) onclick="this.form.name.value="${user.name1}", then there is no problem and i get the right output. But in this way, i can't change the value of all textfields at once and also i can't implement the "clean"-function for the second "click".
I think i use the wrong variable-syntax in the js-function, but i don't know what's wrong there. Is it even possible to get the get the values of the "user"-variable in javascript in this way?
I'm building a multi-language PHP/mySQL -site. I'm also building a CMS for the site.
There are 5 languages. In the CMS fields for e.g. english bodytext are called (id=) 'bodytext_en'. German looks like 'bodytext_ge', etc.
The '_en' part tells us that it's a textfield for english texts. How can i check if ALL english fields are filled out, without defining each and every field separately. Like:
I have a point where the user will get an overlay div, to keep this div centered I move and mess with the CSS property "top". Though, I was testing and when I tabbed into the following textfield, it pushes the div down - as if there is text in the .val() field. (so it keeps going to the "else" statement even just tabbing INTO the field).
Does anyone know how to fix this and keep it from pushing the div down just from tabbing between textfields?
I am trying to query the value of a textfield outside of a form but with no success so far... the reason why I am not using a form is that there seams to be an annoying issue with hitting the [Enter] key (at least in Mozilla) when there is only one textfield in the form... the [Enter] key seams to trigger some type of a submit... but when the textfield is defined outside of a form this is not an issue... However I don't know how to access the value for the textfield outside the form.. Code:
i want to display contents of a form in a plane text format. for that i want to track a number of textfields in the form..... do i need to write a seperate line for each textfield ? i tried
for(i=1;i<7;i++) { var cont[i]=document.getElementById("txt"+i).value ------- ------------ ------------- } but it didn't work out..
I have a scenario with 3 x 12 textfields and looking for a javascript that could do the trick.
What I'm looking for is a smart way of extracting the values of the first three textfields and then multiply them. This will be done for all 12 rows. I then would like to add the result from the 12 rows together to create a final value that will be presented in a seperate textfield.
row1=value1*value2*value3; row2 =value1*value2*value4; and so on....untill row12. then row1+row2+...row12
To show you what I mean I've created a small page with 3 x 2 fields at this link: [URL] The idea is then to have 12 rows and not two. Also - it should call for the function onChange.
I guess combind all the values in three seperate arrays, multiply and then add the values together could do the trick, but so far I havn't manage to do this. Maybe a for(i<12)-code could help.
if ($('input:#hohe_innen').val()< $('input:#hohe').val()){ $('#msg').html("Innenmaß ist kleiner Außen"); } else { $('#msg').html("Inner size is bigger than out size: cause inner "+$('input:#hohe_innen').val()+" and out "+ $('input:#hohe').val());
[Code]...
Inner size is bigger than out size: cause inner 50 and out 100
I'm trying to write a function that does a simple math function between some textfields.
There are 4 variables : Unit price, Discount, Quantity and Total
Unit price is a fixed variable.
Discount, Quantity and Total depend on the fixed variable and also on the values of eachother. (ie : if qty=2 then total=2xUnit Price) etc...
I want to be able to show the changing values in real time.
So if I have 3 textfields and I change qty, I want it to update Total based on the discount and the qty. If I update discount, I want to update Total based on qty and discount.
I'm guessing I would have to write three functions and call each one from their respective textfields.
How to write a function, and call it so that passes the unit price to the funtion, gets the values of all of the textfields and then changes them all to their new values?
In a form, how do I have a set of radio buttons with the last one being an other option that shows and hides a textfield depending on if it is selected or not? I have seen how to disable the textfield if the radio button is not selected, but not how to hide it. Is this possible?
I have an html page with a div element within a form for dynamically creating textfields.
The problem is when I click a link on the page, or the submit button, then click the back button, the new textfields in the div element are not there anymore.
Does anyone know how this scenario is usually handled?
Any way to define the length of a textfield? I have just set all the field with a width so that they look like clear and easy to read, However, When I see the page of mac os, They are totally not the result in IE of FF, Does there any way to define it absolutely?
I have already change the size attribute and set the width of the input.
I want to prepopulate the value of the two textfields with the field label e.g. Name, Email Address, until the fields are in focus.
I have this working for the Name field:
Obviously I can repeat this code on the email field as well, but wondered if there is a way to make it a function with the label value not hardcoded so I can use the same technique on forms with many fields.
The script creates new fields with calendar in a form, if new information is added to a field and then a new field is created the information is lost in FF Live demo: [URL]

I have 3 TextFields, called txtUSD, txtEUR, txtAUS. And a PopupList with the same values, minus the txt part, but I need to form the names of the TextFields to use based on the selection that the user made. So I've done this:
Code: function btConvert_Click(event){ var amount = document.getElementById("txtAmount").value; var rates = document.getElementById("lstConvertTo").value; var from = "txt" + document.getElementById("lstFrom").options[document.getElementById('lstFrom').selectedIndex].text; var to = "txt" + document.getElementById("lstConvertTo").options[document.getElementById("lstConvertTo").selectedIndex].text; var curr_from = document.getElementById(from).value; var curr_to = document.getElementById(to).value; if(curr_from > curr_to){ amount * rates; } else { amount / rates; } alert(result); }
But every time I try it I get this error: Code: mobile/main.js line 215: Result of expression 'document.getElementById(from)' [null] is not an object.
What I would like to do, is to show one image ('1.jpg') if three textfields in my form are filled, but another image ('2.jpg'), if all or any of the fields are blank.
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?
based on selection of radio button, i want to change the text box to enable and disable. And additionally, how to set if i enter a value in textbox1 then calculating something and display the result in textbox2 that to on key up.. not on form submitting.
I'm a real newbie with Javascript, but I'm having fun. I just bought the book, "Simply Javascript" (have only just cracked it so far). I'm reasonably familiar with PHP (I use a lot of it to do simple things). I'm a Web desinger and do custom CSS Websites (I'm fairly new to that too couple of years or more working with CSS and I've never done a table based layout.
[Code]...
But when the button is clicked, nothing will call the showCaption() function again, and I can't figure out how to call that function as the images advance. I have tried a lot of things with a lot of weird results, one being the tne next caption will display in a blank browser window, without the Webpage! I'm not sure why that happens, but I have a clue.
Is there an easier way to do what I want to do? I only want to show a few lines of text that will describe each image. Seems simple enough to me, but I'm just too new to make it work.
i cant get a caption specific to each image to display under the arrows when the image changes. it is especially hard for me because i have to edit the javascript which confuses the **** out of me. it seemed so simple....
ps i cant start an id with a digit? it doesnt seem to cause any problems...why is it stated that this cannot or shouldnot be done?
I am trying to change my cursor to a help cursor for a webapp I'm helping to develop. It partially works, except when an element has a CLASS attribute. For example:
I'm trying to make buttons that change from one color to another when you click them and change back when you click them a third time. I wrote this page (http://cf.lehigh.edu/ems/test.html) but it only works on Firefox(Not IE or Chome, untested on safari or Opera). I'm using javascript to change the button colors. Is there another way to do this that works universal or another tool such as CSS?
How would I go about doing something like this?I want to have a div, and when you click on it the content changes. Then I want it so that if you click anywhere else besides that div, the content should be changed back.So I want <div></div> to change to <div>content</div> when you click on it, and when you click anywhere else in the document it should turn back to <div></div>
