I am trying to create a simple HTML table with the squares of numbers and for some reason the loop is not triggering.
Code:
<table border="1">
<tr><td><h2>Table of Squares</h2></td></tr>
<tr><td>
Number
[Code]....
When I run the page all that comes up is the start of the table that is written before the script executes. Also is there any way I could use a debugger to catch this on my own? I tried the firefox debugger but it didn't catch anything when I ran it through, maybe I was just doing it wrong.
I'm trying to create an associative array in javascript from within the loop that sets up my html table. I can't get my head around assigning the associative key-value pair (probably not the best way of putting it). I've written the below in php. What's the equivalent in javascript? The => is the part that's baffling me.
The idea here is to have a function in javascript that would take the value from one input box (lets call it txbA) and use it as the limit for a while loop or for-next loop and create a series of input boxes each with a unique name so that its value (when entered or changed)could later be used in other calculations.
When I try something like:
function MakeMany() { var y=parseInt(txbA.value); for(var x=0;x<y;x++)
[Code]....
You can call this from a button and get the text boxes, but how do I get them to have unique names such as MMtb1, MMtb2, MMtb3 etc. ??
i was assigned this task(see attached), but for some reason I'm having trouble getting it to work, i don't know if my problem is in the algorithm or if I'm using the wrong structures to solve the problem.
I am trying to create a function that creates an array comprised of filenames based on a given range. I.E if 2-8 is selected and a foldername of UMCP/ and a common name of college is also given, the function should return and array such as [UMCP/college2.jpg,UMCP/college3.jpg.....UMCP/college8.jpg]. Here is what I've got but the alert that should tell me the filename of the first image says it is undefined, how can i fix this?
function getArrayPhotosNames (total,count,first,last) { /*window.alert("get Array Photo Names");*/ var folderName = document.getElementById("photofold").value; var Alias = document.getElementById("commonName").value;
On my form i have multiple select which all have an id value total1, total2, total3 etc so i am trying to detect how many there are and then use this to caculate a total.
Is there a javascript reference to basically go to a form and produce a loop which will show me how many select drop down boxes there on a form.
Or would i have t use something like
for (var i=0; i < frm.elements.length; ++i) { form.elements.length form_field = frm.elements[i]
and then have a nested if to detect if it is select value or has an matching value ..
I have been struggling with a loop of mine. The loop should create a grid, of 204,000 squares(div's). And the total would create a grid field of 340 pixels by 600 pixels. All div's are sized 1 pixel.The idea is to create a grid, that shows temperature data in a gradient style, like a weather heat map. The data is collected from temperature sensors which are connected to a database.The only problem is that because it's such a massive amount of calculations to be calculated by javaScript, the whole thing freezes. Here is a sample of my code:
Code:
function makeGrid() { for (var i = 0; i < 8160; i++) {
[code]....
Another problem is, the grid should be reloaded every 5 seconds or less.Because that's the interval used by the temp sensors, and for the usage that's planned for the project, its really important that the data is constantly up to date. using another web based language are welcome, as long as they are combinable with PHP or AJAX. Or maybe there is a ready to use library that I dont know of. Couldn't find anything for jQuery.
I have several elements that I can perform show hide and fadeIn animations on but I want the action to continue on an endless loop. Is this possible? If it is, are there any cpu usage issues when using a loop? <script type="text/javascript"> $(document).ready(function(){ $(".upright").hide(300); $(".cntrlg").show(300); $(".cntrlg").hide(300); $(".cntrmed").show(500); $(".cntrmed").hide(300); $(".cntrlg, .lowleftmed").show(100); $(".cntrlg, .lowleftmed").hide(100); $(".lowrightmed").show(300); $(".lowrightmed").hide(300); $(".cntrmed").show(300); $(".cntrmed").hide(300); $(".upright").show(2000); $("#dai1").fadeIn(3000); $("#dai2").fadeIn(3000); $("#dai3").fadeIn(3000); $("#june1").fadeIn(3000); $("#june2").fadeIn(3000); $("#june3").fadeIn(3000); }); </script>
I am working on a page that will load in other pages using AJAX and the .html method. Something like this :
<span id = "edit">Edit</span> <div id = "cont"> </div> //the click edit script
[Code]....
Unfortunately this does not seem to work, entirely. It does trigger the click event but it messes up the post for some reason. I have played around with it for the last 45 minutes or so and it seems like the click event trigger is what is messing things up, if I comment it out it works fine. Could anyone tell me why they think this is? note this is an over simplified version of my actual code, but the structure is the same.
i am fairly new to JS for which i am working jQuery but that is for later.right now i am not getting my table printed out when i put input type="text".
here is my code
[Code]...
moreover i m writing this code to later call in a dialog box. using jQuery. but for now why isn't my code being printed with input type. do i have escape "" inside "" like in php? can i make more hierarchy type html in JS, i see when i put the td in next line the code doesn't execute. i guess white spaces have some significance in JS?
I have a PHP script that generates a large, tree structured, table from XML data.Depending on user input, I need to expand or collapse sections of the table (Show/Hide).The way I have written the PHP script, each row is labelled with an "id=" according to its tree position.e.g. block0, block0_0, block0_1, block1, block1_2_0, etc. The buttons for each branch of the tree call a Javascript function, e.g. onclick="return toggleMe('block1')" or onclick="return toggleMe('block2_0_1')", and the toggleMe function knows it has to Show/Hide every row who's id starts with that string. Each row has a unique id, just incrementing the last digit.My problem is that I do not know how many rows there are and what I want to do is to loop through all the rows and see if their id starts with the parameter sent to the function.
I'm basically building a javascript/html calculator but I need the calculation to appear gradually in a table, the table need to be 3 columns accross and add a row each time a calculation button is pressed, the first column can remain blank for now but will need to contain a text field eventually, second column needs to show the calculation symbol, third column shows the number. Here's an example:
I was wondering if someone could help me. I successfully implemented a number of sortable lists, using a table in html. However I wanted to table cells to be scrollable, which does not apparently work, I tried overflow: auto;, overflow: hidden; and overflow: scroll; in css and it did not work, the table cells kept moving to fit the draggable content. I checked on the internet and found that as stated, table cells cannot be made scrollable. Therefore I decided to do it all with div elements. However I want the div elements structured in a 5 x 3 format. Therefore I thought I would implement it in dom. However I am a newby to dom. I have created the following code, which is simple but repetitive, the function createTable simply creates the div elements (1,2,3,4,5...) and writes the class and id attributes to each. I then appended several of the elements into a div container I created, called divcontainer with a class right. There is also a div element already in the document, class and id = 'right'. I therefore tried to add the divcontainer to this. The function however is causing a page error and none of the dom div elements areI would simply prefer to create the divcontainer and append the div elements. Should I take out the div element right already in the document and instead use something like document.body.appendChild(divcontainer) or something similar. Also the function call createTable() should I use window.onload = function(){} instead.

The following code works great on Firefox and not in IE 6.
If I remove the table elements form the variable expor and just output text, the link and the form element and place a <div> with the if form the table and remove teh table it works great, if i put the div inside the table no error but nithing shows on IE. if it put as shown the id on the <table> works in firefox but not in IE I get an unknown runtime error. Is there someway around it? Becuase I want to keep the table for formating purposes as mor fields will be read and shown:
The idea is that the user insert the persons data so afertwards along with some more data it gets summited and in php i get it in DB, but a project can have none or hundres of persons, and always the names are diferent. Code:
Here's my assignment: I have to build a JS program that prints out a 3 column table that lists the sphere radii from 0-25 in the first column, and the corresponding volumes and surface areas in the second and third columns, using a loop. Code:
I am pulling 6 pictures using an array. The output is one long horizontal line of pictures. I want the pictures to populate into a table of two rows, with 3 pictures on each row.
How can I do this?
Here is the code:

im having an issue creating a flashing cell within a table and was wondering if anyone could suggest on how i resolve this.When i do use this the background of the cell stays the original background color and i get no error warning from my degugger.
Write a script to generate two random numbers for variable m and n, the values generated for the variables should range from 1 to 10. We want to make an m * n table (m rows and n columns) with the word Hello in each of its cells. Now define a function f with one parameter n that displays n columns of one row of the table (You need a for-loop). Call this function m times to display m rows of the table. For example if m = 6 and n = 4 we should get the following:
I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
I have a dynamic HTML table which gets populated by coldfusion and displayed in the page, I have a column called performace which holds numeric values. I need to select the top 3 best performace value in the column and then highlight the entire row in different colours (top 3 values for performance). Can any one help me in doing it?My server can run only Javascript and coldfusion, No Ajax/PHP.I need a complete set of code which such that I will add the script and it performs the calculating and highlighting part.
I am trying to create a js script that will prompt the user for a times table (example the 5 times table, the 7 times table, etc.) & prompt the user for 2 more values; the 'start' number and 'end' number. So there would be 3 numbers total the user must input. The script should present a 'warning' message if the user inputs letters or negative numbers. I have come very close to getting it too work but can't quite get past the last hurdle. Upon entering the 3 numbers, the output should look similar to this: (the 5 times table starting with 1 and ending with 12)
Im developing a script for dynamically creating html table structure so that from the input that has been given to the function it will fetch the values one by one and will create the structure. My problem is i want to add attributes to the elements created. sample code attached.
here the element name will be get from the parameters passed to the function. i want to verify whether the line in bold is correct or not coz the id is not updated in output.
