I'm trying to make an ajax post to some php and whenever the user clicks the submit button, it reloads the page and is adding the serialized data to the URL thus breaking the page and giving me an error that I do not have a person selected. I've tried adding "return false;" everywhere I can and it still doesn't work. Here's my code:
I have a number of DIVs that I want to make 'selectable' on click, which means that I give the DIV you click on a class (just to show it's selected) and save its ID into an array. When I click on that DIV again, the class should be removed and its ID should be removed from the array as well. My code goes like
var selected_items = new Array(); $(".selectableDivs").click(function() { if($(this).hasClass("selected")) {
[code]....
But the alert at the end of the code always shows my a list of all divs I ever selected, even those that I unselected again. The IDs are just not removed from the array. Is that maybe because items saved in the array are not exactly $(this).attr("id") anymore?
I am trying to set up a chat window in my website. Pretty much I have the main page, and a pop-out child page that contains the chat. I want users to be able to change pages on the main page, but the issue is that when they change the page, the reference to the child page (where the chat is) is lost, is there a way to make the window object persistent such as serializing it and putting it in a cookie? It looks like JSON is made for like functions, but can't really serialize a window object.
I would like to add a key value to an object array. let's say i have 2arrays: var parArr = new Array('par1', 'par2', 'par3', 'par4'); var valArr = new Array('val1', 'val2', 'val3', 'val4');I would like to obtain ext={par1:val1, par2:val2,pa3:val3,par4:val4}
how to do you add elements to an array? am looking at section dealing with arrays in JS Bible, can't find how you add to an array.. in the last few years I've been doing much more Java than JS, am used to Java, where you can't add elements to an array, but use a Vector instead.. and it's very easy to add to it (use add() method..) how to you add elements to an array in JavaScript..
I looked up array obj, don't see method to add to array.
I want to make a script that will insert all text type inputs into an array. From there I want to be able to call them and edit them. Here is what I have so far and it is not working.
var phone1 = '702' var inputArray = new Array(); var inputs = document.getElementsByTagName('input'); inputs; if (input.type == 'text') { inputArray.push(inputs.id); } inputArray.reverse(); inputArray[0].value = phone1;
im just doing a little test and this might seem like a really stupid question but i cant figure it out...all i simply want to do is take all those numbers and get the sum then display the sum in a document.write in theory i should get 10 but i dont and idk why i have tried many many things
var numbers = new Array(); numbers[0] = 1; numbers[1] = 2; numbers[2] = 3; numbers[3] = 4;
I have a issue that is getting me frustrated I a large arrays of profiles. So I take the necessary arrays out of profile and add them to an small array called items. Then I want to take elements out of the new items array and place the string values into a select array the issue is the default if in the last for loop it will not work it only ever returns the entire string/ array
I have a random image JS that I need to add links to ( well, the same link but to all images) something I am doing is not working. I just need to add a link (asp/course_tool/default.asp) to each jpeg. Code:
I have 8 peices of data in an Array and I need to add the final 6 to give me a total, but the results are not what I expected. Array example - Code:
var Networking_2009_1 = ['Justin Hopkins','JBH','1','2','3','4','5','6'];
I am adding the values like this -
Code: var feeEarnerTotal = 0; for(t in Networking_2009_1) { if(t > 1) // 0 and 1 are the Long Name and Short Name, so must be skipped { feeEarnerTotal = feeEarnerTotal + Networking_2009_1[t]; } }
The problem is that when the value is output to the screen it is '123456' rather that '21' as expected. I suspect this is because there is writte data also in the Array, but I'm not sure how to fix it.
I'm creating matrix of values like this:[code]Usually when i want to access position like Matriz[0][0] y retrived the value "", now for some reason when i debug appears "indexOf" at the beggining and when I access Matriz[0][0] I get "undefined".Someone knows why is happennig this, i'm using IE 6
I'm trying to add together some values held in an array to give a total score. But no matter what I do I get "NaN" instead of the answer. I thought that bunging a couple of parseFloats in there would fix it, but that hasn't worked either.
I'm trying to solve a problem with JS textbox array without success. I have two buttons in my page: PLUS and MINUS; at every click on PLUS a new textbox named 'dear' is generated. So, if one clicks, say, 3 times the output is something like:
dear[0] dear[1] dear[2]
The length property is accessible; alert(dear.length) gives Ɖ', correctly. The prolbem is that is not possible to delete a textbox, clicking on MINUS button. The thing I'd really need to do is to delete from the array (and in consequence from video) the last textbox created, when one clicks on MINUS button.
Pop() and Splice() methods do not work, unfortunely... This is the exact code of my page:
I've got this little chunk of code running on my freelance portfolio site - on each page (different sections of my portfolio) I have 6 thumbnails and a full sized graphic with some descriptive info, you click the thumbnail and it switches the graphic and other info, that all works fine.But on one page I have some web stuff and I'd like to make the var 'clientinfo' into a link to go to the client's website. I know I need to add an array with the website links, but then I'm not sure how to implement it into the html, I've tried various things I've found on here but I'm not getting anywhere on my own. I know it's something pretty simple (for someone who knows what they're doing) but I just can't seem to grasp it.
the js is like this: $(function() { $(".image").click(function() {
Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code.This does not seem to be working for me though. Here is what I have thus far (in short):
<script language="javascript"> var teamNames = new Array(3); teamNames[0]="South Africa"; teamNames[1]="Mexico"; teamNames[2]="Uruguay";
[Code]...
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far.
I am running through a MySQL database using PHP and extracting all of the makes of cars in that database and trying to create a JavaScript array named after each make. Then I am trying to fill each array will all of the models for that make. When I just try to display each Make and Model in an alert box it seems to come up right. And my arrays seem to be getting created but they won't populate with the models (even though my alert msg shows the loops and everything is working).
PHP Code:
while ($row = mysql_fetch_array($result)) { $i=0; //Used so each model is added to the array starting at 0 and ++ $make = $row['make'];//PHP var used to extract data from MySQL

Haven't used JavaScript since a college class a couple of years ago and haven't used it in the real world for even longer. Never with PHP like this. But I am working on this marketing site and need to be able to list products by type according to each brand and as they can be added to a MySQL database it needs to be dynamic. I have the whole thing working by stepping through separate pages using PHP to populate select fields with the data but I want to be able to dynamically add the content to select field using JavaScript so it can all be done on one page and thought that if I could create these arrays on page load then the right information could be selected client side.
I am dynamically creating page elements by looping through an array and adding them to the DOM. Each element has an action that should be performed when it is clicked. This action (or a reference to it) determined by the current array value as well. Because the code called in the onclick handler is not executed until the event fires, the value of the current array item (at the time the onclick handler is attached) is not preserved resulting in the expected behavior not happening.Here is an extremely simplified example of the problem I'm facing:
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I have a set of regular expressions that make heavy use of the | operator on sections that I do not really need to extract a match from. For example:
Code: var regexp = /([A-Z][A-Za-z]+) (jumps( high)?|leaps|bounds) over ([A-Z][A-Za-z]+) and (grabs|snags|gets) (a|an|the) (apple|orange|pear|grapes)/
The important part for extracting from the match array after using regexp.exec() are the names (the ([A-Z][A-Za-z]+) parts), I don't care which of the other things are matched. The problem is that using the | operator seems to necessitate using the () and adding a term to the match. This makes it difficult to know which term in the array will be the names, especially after editing the middle.So I'd like to be able to use the | operator on words and phrases without adding terms to the match array.
I having been trying to make the data from generated (using div tags) pairs of textboxes into two separate arrays, a[] and b[]. I thought that if I label each text box pair a[i] and b[i] that would be enough to include the respective element in each array but that hasn't seemed to work. In fact. the only way I managed to retrieve the values from the text boxes was using "getElementById" and resorted to a for loop in order to make the arrays but that method appears to be able to get elements from only one pair of text boxes. Code:
I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target
Once again I call on the gurus after banging my head against the wall for a few hours. I use .clone to clone some elements then I get the various values in an array. All that works fine. However, I want to total up the array so I can validate the total against another value.In the code below if I put the x array in the sum such as sum(x) and alert(quantityTotal) it shows 4 as expected. If I simply alert(quantities) I get 3,1 however, if I sum(quantities) and alert(quantityTotal) I get 013 instead of the expected total of 4 I'm baffled (as usual..haha). Must be something simple I'm missing.
var quantities = [];//quantities array $.each($('.quantity'), function() { quantities.push($(this).val());
