I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I am new to learning JS and am trying to create an array through a prompt. It seems to work, but I believe it is treating the prompted numbers as strings not numbers.I am parsing the negatives and zeros, and positives and counting them. It doesn't recognize the negative sign.Here's my js:
function counter() { var numArr = new Array(Number(prompt("Please enter and array of numbers, in any order, separated by a comma..." + '[code]......
I've been wondering lately: is it possible to create an array of some html tags (let's say array of <div> or array of <p>)? Something which would allow me adding a new <div> or <p> to the array.
I am to make a small html webpage in which there are supposed to be 2 text areas: in the first are certain words (for example tomorrow, money etc.), and in the second one there is an input text (let's say "Tomorrow you must send me the money I need"). Javascript should do this: print the input text in a paragraph/div, highlighting the words mentioned above. Something like: Tomorrow you must send me the money I need. This is how I thought of the array of tags, which can at any time add a new word to the output paragraph, it's only to be chosen whether to highlight it or not.
I'm trying to create a multidimensional array (and it's my first time using one) as an easy-to-modify way of populating content into a cycling banner script. However I seem to be having issues with actually accessing the content in the array.So currently my array looks like so:
Code:
<script type="text/javascript"> var banner = new Array(); //Option 1
[code]...
But when I do a "document.write(banner[0]['title']);" in my body, it doesn't seem to want to oblige.
I have a list of about 70 servo's that I'd like to apply set properties too.As they all have the same property set but with different values I thought I'd try creating a servo object, the create an array of servo's but I don't think I'm getting anywhere fast.[code]...
Once this is done and I've got all the servo objects created with their properties, I'm hoping to be able to search for all servo's with a set property i.e all servo's with servo.application = 1 would that be possible, if not I geuss I'd be wasting all our time trying to create classes I can't use the way I'd like.
I must begin to say that I'm rather new in wtiting and using JavaScript. Now I want to use JavaScript in a HTML-page. On the homepage is a link. Every time the homepage is displayed the link must point to another target. I want to realize this by having a lot of differet targetpages. The names of these pages are p1001.htm until p<nnnn>.htm. At this moment the last is p1153.htm, but the amount is increasing every day.
I have a file named "counter.txt" which contains one line with the string of the last targetpage, at his moment "1153".
My idea is to have a JavaScript which: 1. reads the file counter.txt to determine the last available page 2. then takes at random one number between 1001 and 1153, 3. sets the HREF-link to page p<random>.htm.
I know it must be possible in JavaScript, but can anyone help me?
How would this be written on .js file. I need to create a variable named dateString which is equal to the following text string: weekday, month, day, year.where weekday is the name of the weekday, month is the name of the month, day is the day of the month, and year is the four-digit year value. (HINT: Use the wdayName array using thisWDay variable as the index value to display the weekday name, the monthName array along with the thisMonth variable to display the month value, and the this Year variable to display the year value.)
I have a php page that names checkboxes in a form chkwhatever# and increments the number depending on how many items there will be. In my javascript i want to be able to check to see if any of the checkboxes are checked but I cant use document.name.chkbox+#.checked. Should I create an array with the checkbox names? Not sure how to go about this.
Now in extension js file i want to check if check box is checked then create the variabel like CB1 (1 is the id) and the i want to assign value to this variable
i did something like this
[code ] //arrayLength is the no of check boxes for(var i= 0 ; i <arrayLength; i++) {
I have a form, that when the user click Submit, I need a php variable to be echoed to the page. This is for an upload page. So when they are waiting for the file to upload, it will say "Uploading..." until the upload is complete.
All I know so far is I need to create a javascript function and include it in the submit button. This is all I have so far in the submit button tag: onClick="Transferring();"
I need to create 14 javascript Ajax objects and assign properties and events to them. Since most of the code is just being repeated, I'd like to do the whole thing in a loop using an array for the object names. This is a portion of the code as it now stands:
boxe2_tree = new dhtmlXTreeObject("boxe2_div", "100%", "100%", 0); boxe2_tree.enableCheckBoxes(1); // etc. boxe2_tree.loadXML("./xml/boxe.xml",function(){loadTree('boxe2_tree');}); warn2_tree = new dhtmlXTreeObject("warn2_div", "100%", "100%", 0); warn2_tree.enableCheckBoxes(1);
I am wondering what the normal practice of creating an index variable is in javascript. I am wondering because I have just entered learning javascript through jquery. There is some pre-written code I am using to learn by and I am unsure of how their index variable is working in the code.
Here is the code: Code: jQuery(this).find("li").each(function(n) { // <-- I see that 'n' is the index
I can get the outcome of this function into a variable that I can then use later on. At the moment it obviously alerts the answer but I just want that answer in a variable.

is there a function that get the name of the first input field of the current form ?
in my example below I want create an array of form field name and in the onsubmit assign all element's name to create a simple iteration to test if some elements in my array, that must be required, are null:
something like function verify(array of string)and in onsubmit something like return onsubmit(field1,field2,field3....) Code:
