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. ??
make my script smaller by creating a function that controlls every textboxes instead of one textbox. See below my code that I want to make it smaller...
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 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 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 have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.
I have the code below, how could it be modified to loop over and over and reload the xml file each time. Flow would be: load xml, run thruogh code to display each xml node one at a time, when reach last node, start all over, reloading xml file,
i want to make a section using javascript that may incoporate user input counters. for now i'm trying to make it so that if you type in a phrase or sentence in a textbox and a letter in another textbox, it will count how many letters are in the phrase. the point of this is i want to be able to categorize famous phrases by the number of specific letters they contain.
I have two text boxes and I want them both to submit the same data, such as if the user changes one text box, the other changes to the same value and vise versa. I am easily able to make one textbox update the second with javascript, but not the other way around (it either won't do it, or neither textbox will accept a value).
I tried two different js functions, tried two different if statements in one function.I'm using onkeyup (vs. onchange), though I don't know if that's important or not.It's best not to ask WHY I want to do this, because my explanation will be dumb. Honestly it's to save from having to do an extra IF statement in PHP (and because it looks cool for the enduser).
I need to get the values of all textboxes that I've generated through dropdown list using AJAX. I've been getting only the last value of the textbox, I can' seem to loop it. Anyway, here's my [code]...
I am trying to check some textboxes if they have no value, and a listbox. However, with my current code, it seems like the OR code is not working like it should be. <script type="text/javascript"> function checkEmpty() { if (document.editForm.varenummer.value!="" || document.editForm.serienummer.value!="") { if (document.all("reakke").options[document.all("reakke").selectedIndex].value == "2") { alert(); } else { document.editForm.submit(); }} else { alert("Indtast venligst alle informationer"); }} </script> As seen above, if Varenummer or Serienummer is not equals nothing, then check the listbox, but if they are nothing then do the else statement. However as I tested, the else statement only triggers if both Varenummer and Serienummer is nothing.
I'm looking for a way to write(type) within two or more textboxes at the same time. So if I would write ''hello'' in textbox A, this word will show in al other textboxes (type input - not textarea).
I have 2 textboxes (textbox1 and textbox2) and one hidden field (hidden). I want the value of the hidden field to be both values of textbox1 and textbox2 separated with "-".
it works fine but when it enters the text - 'http://' - the cursor jumps back to the start of the line in the text box. How do I then make the cursor be placed at the end of the text. For example:
This code works fine for IE8, IE9, and Chrome. But not for IE7. I have tried jQuery versions upto 1.6.1. Is there something wrong with jQuery in this case? Do I have to resort back to classical JavaScript for IE7, which you know, is a difficult task to do.
creating a function that changes a specific CSS property for all 'asp:TextBox' type controls that have the CSS class of 'style1' this function should fire when I click the 'btnTest' button
