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 have this code:if (! $_POST["Name"] || ! $_POST["LName"] || ! $_POST["email"] || ! $_POST["phone"]) { $Alert_Message = "Invalid Form"; }i got a js script from another forum here on this site that looks like this, and does work well:print <<<JSOUT <script type="text/javascript"> confirm("Form is INVALID");
[Code]...
exit;i have 4 different messages that i want to choose from to be displayed in the js script, and I want to store the message that i want to use in a PHP variable along the way. the variable is: $Alert_Message . i am trying to do this with my confirm() function in js:confirm($Alert_Message);the code is not registering, so something is obviously wrong. can i reference PHP this way in a js script? if not, how would i go about doing this another way? can i change a js variable along the way in my PHP code instead, and then reference THAT variable when i get to my js script?
I declare multiple variables halfway down the page. The number between "mech" and "Num" is generated dynamically in the XSL. Later on I need to reference that variable in a function, but I need to build the variable name in script. How do I convert it from a string reference to a ref to the global variable?
function changePreference(pos,mt){ //mt does not reference mech2Num, I need it to. } changePreference(2,'my' + pos + 'Num');
var mech1Num=1|2|3|4|5|6; var mech2Num=1|2|3|4|5|6; var mech3Num=1|2|3|4|5|6;
How do I store an object reference inside a variable when I want the object reference to to reference the first "ul" html element nested inside the current object (as referenced by this keyword)?

Is it possible to use splice() with a variable index. I understand that splice(1, 1) means start at index position 1 and remove 1 item. However, I want the index position to be a variable, since I don't know the actual index number of the item to delete at runtime. Is this possible?

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.

I have the below array called "results". When I loop through all document elements I would like to check "field_name" against the "results" array and see if it exists and what index number it is at??

I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s
jQuery(document).ready(function() { var active = $("#tertiarynavigation .bordered").get(0); var num = $("#tertiarynavigation li").index(active); alert("Index: " + num);
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 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.

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);
