I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.
This is a FAQ page I built with custom jquery function that toggles the answers open/closed on click of a question, and Im just wondering if anyone has a suggestion to make the code leaner and meaner:

I am building an online store where the customer can select custom parts. I'm quite new to javascript, but I've managed to create a radio button list, where the price is added from each section. I would like a box to show all of the options selected, not just the sum total.
I've included the text with value and used parseInt. I have been told I can use value.split(" "), but I don't really know how to go about doing that. I've been fiddling for hours now and don't seem to be able to get anywhere.
I would also like to include a 3rd value, another number, and add that one in a separate calculation.
E.g. For "50 5850ati1gb 56" I would like one calculation which adds 50 to the total, another calculation adding 56 to a different total and 5850ati1gb added to a list of all of the components.

I am not very experienced with this, so don't be afraid to talk to me like I'm stupid
I have been starting to use Javascript a lot lately and I wanted to check with the "group" to get your thoughts on code efficiency. First, is there a good site/book that talks about good and bad ways to code. The reason I ask is because I was just thinking about the following...which is better and/or why?
document.forms["myform"].elements["txtname"].value or document.myform.txtname.value
I would like to be able to display or hide fields based on whether a specific Yes/No radio button is selected. This is in conjunction with a posting a just made here in the same group related to checkboxes.
I am having trouble getting the following code to work. I just want to make the script in the head work, the html in the body is to stay as it is. I want to use an array. I can make it work very well without an array, using separate conditional statements for each radio button, but that is cumbersome. Can someone please tell me what I am doing wrong with the script in this code. I have stripped the page down to the bare essentials for ease of viewing. Code:
I don't know if it's appropriate to discuss a JS library here, but I'm wanting to use jQuery to toggle the display of content based on a selected radio button. Here's an example HTML
Obviously the idea is that only one block is displayed at a time. I'm happy to get the effect anyway possible, but I do want to use jQuery because I believe it will be easier in the long run.
What I don't know how to do is to use the value of a selected radio option to show a block with the same ID as the value. I'm also not sure if I'm correctly select a name when I use $("[name='toggler']").
EDIT: Actually, I don't seem to be able to select the radio buttons using any other method than $("input"). Even if I give each input the same class I can't select it using $(".toggler").
This seems to work perfectly across all browsers except for IE (latest version).
In IE the only problem is that the radio buttons have to lose focus before the span will change to visible. I would like the "specify" field to display immediately after the radio button changes to yes, rather than waiting for the buttons to lose focus.
Since jQuery parses the entire dom first, is there any efficiency gain in directing it via the entire CSS chain rather than directly to an ID? That is, if I have a Div with an ID of "foo" and it contains a P with an ID of "bar", is there any speed advantage in using $(div#foo p#bar) as opposed to just using $(p#bar), assuming jQuery would be more efficient if it had both indexes?
I am very exciting about jQuery but a am not programmer and the way I write functions is probably not most efficient. For example I have 12 collapsible panel that I need to control. Is there better way of writing this?
I have some tables with rows greater than 100 and this brings client-side sorters to their knees... Any recommendations on a good, front-end table sorter?
I see in a book how to use javascript functions from radio buttons to display text into a form textbox, but what I want to do is instead of display text into a textbox, to display images positioned by CSS. My code is below. All I get is the initial display of radio buttons, the chosen one chosen, and that's it. No display of images. I tried even just using text and no. Here's my code:
I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..
Im trying to configuere a form that a.a radio buttons that allow the user to choose between quarters, nickels, dimes and pennies and show image when click on my radio button.how to get the image to display whenthey click on the radio button?
I have 10 buttons on a page, and 10 more "onmouseover buttons" that correlate to the first set. Each button or onmouseover button is only 1-2KB! But I can still hold the mouse over a button for a couple seconds until it loads the onmouseover button. I'm using javascript to have the buttons change. The page does load a 2MB video. Could that be the cause? Can I tell it to load the buttons first somehow?
I have a nice search engine but its seems i can't put it twice on the same page: <script language="JavaScript"> function startSearch(){ searchString = document.searchForm.searchText.value; if(searchString != ""){ searchEngine = document.searchForm.whichEngine.selectedIndex + 1; finalSearchString = ""; if(searchEngine == 1){ finalSearchString = "[URL]" + searchString; } .....
How to put the code twice in the html page without creating a conflict as a result of identical codes?
I'm currently modifying a php controlled website and wish to distinguish between javascript and non-javascript browsers in order to decide which pages to display. I have a single php controller script which "includes" a number of html pages. I want to ensure that I cater for both javascript and non-javascript browsers (so functionality is the same, only the javascript pages have a far better look and feel to them).
Therefore I would like to code something along the lines of :
Code: if (javascript_browser=='true') { include './javascript_page1.html.php'; exit();
Firstly it generates two numbers. One is the sum of the CharCodes and the other is the product of multiply each of the charcodes together and usisng the Modulus function.
If the text string is correct, the string is then used to decode (via a relatively simple crypt) another string, which then gives you the correct target url.
I hope that makes sense - if it doesn't, its pretty unimportant as the question I have is as follows :
In javascript, how do I code something that allows me to cycle through all the possible text strings. Ideally, I would like to read from a dictionary file and then start a brute force.
Throughout each cycle, I imagine you just set input_user (in this case) to the value of the next line in the file. For a dictionary attack I imagine. That bit isn't too tricky I don't think but I can't get my head around it. Maybe more coffee would help?
And I'm sure struggling to put together a brute forcer so I turn to you guys and gals to ask if you could help me and point me in the right direction on how to code this.
I'm assuming also that the code we end up with, would be generically useful too as in we could vary the output (going to input_user) in this instance to another variable and use it with another script?
I need advice about creating an order form (I was sent here from the General Web Building forum!) and I have been told that JavaScript is the way to go - can anybody help with the following (I know nothing about Javascript really).
I have an order form and plan to have the data emailed to me (I have FormMail script installed on my server). The form will have the following fields:
Reference Number Size / Cost Quantity Grand Total
Clients will enter the ref no., choose a size/ cost (radio-button), and quantity (text box). I plan to accept details for about different items. I just want the total cost to be displayed in a box at the bottom before the form data is sent to me.
Can anybody point me in the right direction of how I might go about this? Tutorials / sample code etc.
