I'm trying to determine if the id of an element matches a String that has multiple parts.
Code:
function platformChange (this)
{
thisID = this.id;
[code]....
The value of this.id is "platform_SWFUpload_0_0" but the result of thisID.match (pattern) is null.
I need to make script which takes from one field string(numbers separated by space copied from excel) divide it by space into variables and insert into another fields on this page. <textarea name="receiver1" id="receiver1">
View 1 Replies View Relatedis there any way one can test if an element matches a jQuery selector? I'm not trying to locate elements, just test for match.
More specifically, when using event delegation and a common callback function for multiple events, is there a way to check the event's currentTarget against a selector?
In the following example, how can I check if the currentTarget is the LI node with class "item2"?
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>

I was wondering if there is a "selector construct" that matches an element having more than one child. So I'm looking for a solution that doesn't need
an if statement such as;
if($('ul').children().size()>1)
{
//do this
}
[Code]....
But I'm looking for a selector that already looks for these conditions. Kind of like how :has() works but then a check for more than one child.
Any jquery plugin can check number of word in a string instead using of .length?[code]
View 16 Replies View RelatedI 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 find the correct syntax to use to determine whether which form
element is visible on changing the value in a dropdown list
I need something in the onChange of the dropdown list that will cause the
appropriate element on another part of the page to be displayed Code:
var mydropdownlist =
document.questform.typeid.options[document.questform.typeid.selectedIndex].v
alue;
if(mydropdownlist<6)
then display <input name="ans1" type="text" >
else
display <textarea name="ans1" rows="1" ></textarea>
Is it possible to dynamically determine the current field element in a
form?
I ask because I have a 'tab' button on a form, and when a user clicks
on it I need to be able to shift the focus to the next field, and also
if the current field is the last field on the form, essentially to do
nothing.
Conceptually, I guess I'm trying to do something like:
function clicktab(){
variable = current.field.element.number;
if (variable < n) {
variable++;
document.forms[0].element[variable].focus;
}}
In the above function, "n" would be the total number of fields in the
form.
I have a floating div that stays at the bottom of the browser window while the user scrolls down a long page. The div reads "scroll down for more". How can I determine the current position of the div in relation to the top of the page, not the top of the browser window. I need to determine this because I would like to hide the div when the user scrolls to the top of the last page. I have looked at offsetParent, offsetHeight, scrollHeight, etc.
I have the code for everything except determining the position of the div, or the distance of the div from the top of the page.

I have this odd situation in which a function receives an element that needs some cleanup; all events to which it is bind to should be removed
Unfortunately, I don't know if the events are bind using 'bind' or 'live'
Is it possible to use find this out somehow using only this element ?
In IE (tested 7 and 8), $('td[colspan]') seems to match every single td. In Firefox and Safari, though, it (correctly) returns only those which do have a colspan attribute. Here is a simple test:

I have a form with two fields: shape and color. where people select a shape an image of the shape appears, and a default color image appears.When they select a color, it changes the color image. But if they go back and change the shape, I don't want it to turn the color back into the default image. But I don't know how to do this script.Here's the function I have, but I don't know how to write it:
function changecolor(picName,imgName)
{
var idx = filepath.pic4
if (idx = "/images/leaf_shapes/entire/transparent1.gif")

It's to allow users to create thier own descriptions, and the input is displayed automatically using innerHTML. This part of the function checks if the HTML tags are allowed through, I've got this far...
allowedHTML=new Array("<br>","<b>","</b>","<i>","</i>")
HTMLcount=allowedHTML.length
function formcheck() {
lettercount=document.formname.email.value.length
HTMLcheck=""
for(i=0;i<ltrcnt;i++){
if(document.prsnlsd.email.value.charAt(i)=="<"){openat=i}
if(document.prsnlsd.email.value.charAt(i)==">"){closeat=i+1
for(j=openat;j<closeat;j++){
HTMLcheck+=(document.formname.email.value.charAt(j))}
for(k=0;k<HTMLcount;k++){
if(HTMLcheck==allowedHTML[k]) return; else alert()}}}}}
I want it to trigger if one of the "allowedHTML" isn't found by the time it's finished going through the array.
I want to set predefined URLs and display some HTML when the URLs are loaded on the page where the code is. Let me give you an example implementation.With forum software, you get one template file that makes up the view forum page. I want to display a piece of code ONLY when someone visits a particular forum. So, I want them to see it when they visit:

Not when they visit:

how to make a function that changes a specific image on a page when the user chooses from a menu, but only if the src name matches "transparent.gif"
With numerous other scripts, I've cornered myself into this as the only solution for now to what I'm trying to do. But the script is not working. Here it is:

I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
Code:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
[code]....
I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.
I must be having a brain cramp, but I having a problem that is so very simple ... but can get my head around it.

I have an element tag stored in a variable: var bla = '<img src="path/to/image.jpg" name="something" id="myid" />'; Is there a way to get that id from that var??
View 1 Replies View RelatedHow can I go about making it so JavaScript will not let a form submit unless a number entered into a field matches a pre-specified number?
View 3 Replies View RelatedCan't figure out why the pattern will match a period but not a square bracket.For example, it will match "See Jack run." but not "See [Jack] run.". Just ignores the brackets.

I have several checkboxes that on .click add their ID to an xml string. I am having trouble with it adding multiple ID's, currently if you have one checked and check another, it overwrites the previous. Here's what I have:
if ($(this).is(':checked')) {
services += '<SERVICE><SERVICECD>' + this.id + '</SERVICECD></SERVICE>';
}
How do I make this work with multiple ID's so it adds/removes each one based on click, not overwriting? I need to be able to have multiple ID's added to the string.
How would one search for more than one one simultaneously? I have this function:
var flix = ["Any items left unattended on this table" , "Hello, World"];
function Multiwords(s){
var a = flix[0].toLowerCase();
var b = s.toLowerCase();
var result = a.indexOf(b)
if (result >= 0)
[Code]...
It's pretty basic, it just searches through the first index of var flix and tells me if the parameter (s) is 'found' or 'not found'. I made it not to be case sensitive. However, how would I search for multiple words for example:
Multiwords("ANY items This") and if any combination of 'ANY' or 'items' or 'This' is found, i still get my alert message of 'Found'?
What I am trying to do is have an input box where the user inputs a word(s), the a button which onclick changes the user's input data so that each line is modified to have a "<<" before the word and a ">>" after.
For example :
user types:
apple
orange
pear

I ran into a problem that I could not fix myself, I am trying to replace a string with another string, the replace lines look like this:
Code:
var word = document.getElementById("word").innerHTML;
document.getElementById("word").innerHTML = wordd.replace(/B/g, '<span class="style106">B</span><span class="style107"> </span>');
It works just perfectly if left alone, but I need to replace every letter inside this string, adding those style and span tags around each and every letter. So if I add another line to this code, like this:
