Variables / Frames - Cannot Find Specified Form And Input Area
Aug 25, 2009
I have a javascript function that sets the value of an input area on my page. I need to update the function so that it also sets the value of the input area on a separate page. Currently, I am using a frameset, so I can see both pages simultaneously, but I cannot change the value of the upper page from the lower page which contains the script to update the input areas.
Here is my code:
document.lowerForm.inputOne.value = myVar; //Successfully Updates Input Area.
document.upperForm.inputTwo.value = myVar; //Cannot find specified form and input area.
I am pretty new to Javascript and have only created a few pretty basic scripts, mainly dealing with site navigation and mouseovers. I would like now to redo my private home page using a rather complex configuration of frames. It is my intention to use JavaScript (variables) to control the rather intricate page navigation.
My question is this. I know how to define a variable, increment or otherwise alter it's value and how to change a process path based on the value of a variable. I have done all of this within the SAME page. What I would like to know more about is the referencing and modification of variables in "pages" in other windows within a frameset.
I am trying to create a text area input filed for user input, and i want to be able to allow the user to format thier text, just like the ones used in this user forum. I am writing my website in html, php, javascript and css with a MySql database. I am trying to understand how to create such an format-able text area for input.
I have an image that I set to have a width of 100%. I want it to be no higher than the screen height. Its inside a div which itself has no height limit set. So I thought I could set the image height to screen.height. But when I do that, it seems to be larger than the visible client area of Internet Explorer. I want it to fit within that space. I realize the image might be distorted by doing that, but thats OK.
I'm trying to find the position of an element with respect to the view port area. So, when the user scrolls the page down, I want to know the x and y positions of the element with respect to the viewing (view port) area.
The overall goal is to know exactly where on the element this user clicked.
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:
Here is a script for limiting text area input. It also shows the remaining characters. Simply change the start value for "Characters remaining" to adjust the max length of the form.
<html> <head> <script type="text/javascript">
//Original Script By: Adam Matthews //Date: 05/05/2005 //Posted at: http://www.codingforums.com var max=0; function showChar(obj) { var obj3=document.getElementById("char"); if(max==0) { max=obj3.firstChild.nodeValue*1; } len=obj.value.length; var cur=max*1; cur=cur-len; if(cur<0) { var obj2=document.forms[0].elements['comm']; var str=obj2.value.substring(0,max*1); obj2.value=str; showChar(obj2,max); return false; } else { var obj2=document.getElementById('char'); var str=document.createTextNode(cur); obj2.replaceChild(str,obj2.firstChild); return true; } } </script> </head> <body> <form> <textarea name="comm" cols="20" rows="3" value="" onkeyup="showChar(this);" onblur="showChar(this);"></textarea> <br /> Characters Remaining: <span id="char">200</span> </form> </body> </html>
1. First form on the page has questions with radio buttons. Each radio's value is a number so a score is assessed at the end.
2. Second form on the page is an email the admin form, which duplicates the score in one field.
Question: I would like to know how to write the form results to a text area in second form. However, I can't do this for one, and secondly, the value is a number, can I use labels? Here's the code I've 'made up' so far...
I have a drop area that should be pulling a value from a hidden input field when activated.For some reason, the code can see the image and set the new values but trying to get the value of the input field always comes back undefined. It's the $newSKU2 value that isn't getting set.
var $newpic2 = $('#2').find('img').attr('src'); var $newtitle2 = $('#2').find('img').attr('title'); var $newtext2 = $('#2').parent().parent().find('font').text();
i'm trying to figure out how to access my input text with a variable:
Code working: function 123(param){ var x = document.form1; total = 0; if(x.txSecurApp.checked){ total = parseFloat(x.tAdulteA3.value) + txSecur; } else{ total = parseFloat(x.tAdulteA3.value); }}
Trying to : function 123(param){ // param is tAdulteA var str = param + Ɖ' var x = document.form1; total = 0; if(x.txSecurApp.checked){ total = parseFloat(x.str.value) + txSecur; } else{ total = parseFloat(x.str.value); }}
the var str is the problem, can i access my input this way.
I want to test if a input field is empty or not, if it is I don't want to execute the rest of the script. After googling I thought I might of found a solution but it doesn't appear to be working :( Even if the input field is empty my script still executes.The solution I found How do I test whether an element exists?The only thing I really add was:
if ($('#phone').length) before $('#search_customer').blur(function() to test the input field add_reservation.php
How i can find the parent div of this input field for example someone type into the input field on keyup we want to find the parent div of this input field
Code: function get(obj) { var getstr = "?"; for (i=0; i<obj.getElementsByTagName("input").length; i++) { if (obj.getElementsByTagName("input")[i].type == "text") { getstr += obj.getElementsByTagName("input")[i].name + "=" + obj.getElementsByTagName("input")[i].value + "&"; } I have a form with input objects enclosed in a table, but this part of a script cannot find the input objects unless it is outside the table.
Is it possible to input var x for example into "<font size:"x">" and make it higher each time I push a button? Or is there any other way to make text or table or picture or whatever bigger, smaller or just differ it after an event?
I'm a student learning web design and having a problem with some javascript code, I'm validating a text area, i dont have a problem limiting how many characters can be typed in the textarea, but I cant get it to give an error if there is no text in the text area. In the code below the validateMes() function is not working, the other functions work fine
If i use my ajax form on its <b>own</b> then it works and submittes the data... if i use my tab to call the script then the submit will not work and im presuming its the ajax.. i havent changed anything but the link!?!?
How to pass jQuery variables to PHP script ?I have a simple page here that uses the PHP GD library to create an image of text in a font at a set size.Select the text, size and press set and the text should be set at that size.http:[url]....I want to do this without the page reloading so I'm trying capture the input with jQuery and pass them to the php script.
Alerts show that the correct info is being captured.The php script is being called because it's that thats producing the grey box on the page.The problem is the text isn't being produced with the box.Am I passing the jQuery variables to PHP script correctly ? How can I check they are being received by the PHP script ?

I'm making a page for my daughter's school - or trying to. they are having a silent auction and i'm trying to make a very simple bidding page. where i'm running into problems is passing the bid to a text box (read only) where it can be updated when a new bid is entered.
I would like this to be in the upper part of the page with the listings of the auction items, i just can't wrap my head around how to do this. I've gotten as far as the form for entering the bod and contact info. I have the php code to submit. i still have to get the validation js to make it more secure.
I'm trying to do the standard show/hide DIV, but the system I'm trying to use it in is basically this: My site has an application form submit area, and I've got a page where I can view a table with all applicants' details. One of the table fields is just a link to "view full message" (which is a text area field from the form), what I want to do is have this link display in a DIV elsewhere on the page. It needs to change according to which table row is selected.
