I have a function that requires the ability to count the number of entries in an array.
I'm using the following to call my function inside an input tag:
Here is the javascript:
And when errors.length is alerted, it outputs 0. I can only figure that there is an issue when using custom named keys in an array, since this works when I use only integers, however, I have the need to use a custom key index as shown.
What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
I wrote a simple code in javascript and it is working fine with IE and Firefox but the out put in php array count is correct in IE but not correct in Firefox
<script language="javascript">
var arrdimensions = {
"codimesion":{"s":{'0':'dimesion1','1':'dimesion2','2':'dimesion3','3':'dimesion4','4':'dimesion5','5':'dimesion6','6':'dimesion7'},"c":1,"m":"50", "sc":1, "f":"nopcs[]"}
};

I've created a script that should display a certain image based on the day of the week and the time of the day. After uploading the page to the site I receive no errors, however I'm not getting the display I should be seeing. It always returns the image from the final "else" statement. I'm thinking the problem is that I have two "&&" operators in each "if" statement, and I don't have the proper syntax, or perhaps I'm not writing it properly. Code:

So if the url was http://localhost/dma/505/ then the function would look at the address bar, set the 505 to a variable then use that variable to look up the dma name in the array. The last part is where i'm having issues. Code:
Is there something wrong with my script? Typo?
function accite() {
bq = document.getElementById("content").getElementsByTagName("blockquote");
q = document.getElementById("content").getElementsByTagName("q");
alert(
"<blockquote /> = " + bq.length +
"<q /> = " + q.length
);
}
It's saying "document.getElementById('content') has no properties", and yes, I definitely have a <div id="content" />.
The event which in the following keydown function code is not returning the correct key codes. I have checked this in Chrome using the developer tools and the console.log(e.which) statement in my code.

I am trying to do a simple check-all / un-check-all checkbox system.
All of the solutions I have seen use "this.form.elements.length" or a
variant of this.
My scripts don't work because "this.form.elements.length" always
returns 0. Example:
document.write(this.FormName.elements.length);
displays "0"
Am I missing something obvious here?

The mysql-query is: $term%, but there are all items shown (like % $term %), why?
I am having some trouble with this form .It is not returning any errors, it is simply not returning the results of the form fields.
The clear form works, the redirect works, the layout is fine, just no results. I am just beginning to learn Javascripts and I know this is a pretty basic script.[code]...
I have the code:
console.log($(this).parent().parent().children());
console.log($(this).parent().parent().size());
And the output is:
jQuery(td.center, td.center, td.center, td.center, td.center, td, td) 1
Why is the size() 1 and not 7?
the script is supposed to allow the user to enter a minimum and maximum value and then enter the number of random numbers to generate between the min and max.
then it is supposed to floor these numbers and post the in a single column table. my script is writing the table correctly but the numbers arent coming through
Code:
<table border = "2">
<script type="text/javascript">
var min = window.prompt("Enter the 1st number","");

View 1 Replies View RelatedI am trying to create a Table of Contents from a html document that has h1, h2, and h3 tags. In my js code i retrieve the h3 tags for a given h2 tag and store it into a variable called numSubs then in my for loop i set the condition j < numSubs.length but the problem is that it keeps saying that numSubs.length is 0 so the for loop never gets implemented. why numSubs.length keeps getting set to 0 when it should be 1 or two?

I'm trying to use google maps for the web application I'm developping. The idea is I have a database with all the universities with whom we exchange. I know where each university is (city). What I want to do is show all the cities on a google map (as markers)Here is the code I am using:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">[code].....
The code works well, it finds the cities and places a marker at the appropriate place. BUT, only 18 out of the 73 cities are shown. If I take away some cities from the list, the others are found. All the cities can be found this way, but only up to 18 appear at a time. how to avoid having this limit?
I'm currently working on a javascript form validator and have run into a problem. The validator is used to make sure that the customer has entered a number in the quantity input box of the item they wish to purchase.
Code:
function validateRE(fieldToCheck, strRegExp, msg, min, max) {
if (!min) { min = 0 }
if (!max) { max = 100 }
for (i=0;i<15;i++)
{
if (fieldToCheck[i].value) {
var re_pattern = strRegExp;
if (!re_pattern.test(fieldToCheck[i].value) || fieldToCheck[i].value.length < min || fieldToCheck[i].value.length > max) {
alert(msg);
fieldToCheck[i].focus();
fieldToCheck[i].select();
return false;
}
}
}
return true;
}
Used with:
Code:
<form method="post" action="../some_URL"
onsubmit="return (
validateRE(this.quantity, /^[1-9]{1}$|^[0-9]{2,3}$/,
'Please enter a Quantity.', 1, 3)
);">
The part in question is the red highlighted section.
The number of items that is under a specific product is generated dynamically and can range from 2-20. How can I get javascript to count the total number of items and run "for i=0;i<total number" instead so it is different for each product page?
I am using a js calendar script that populates a text field with a date. When clicking in the field the calendar shows then i choose a date, calendar closes, the date is now in the field. great it works fine.
example- *note, array use[]*
<input type="text" id="example[]" name="example[]" value="" onfocus="if(self.gfPop)gfPop.fPopCalendar(this);return false;">
I want to make this call from a button. when adding the code to a href, the popup shows but nothing happens when selecting a date. I have tried the following scripts will failure.
*html a href and img tag left out*
onclick="if(self.gfPop)gfPop.fPopCalendar(document.this_form.elements['example[]']);return false;"
onclick="if(self.gfPop)gfPop.fPopCalendar(document.this_form.example[]);return false;"
onclick="if(self.gfPop)gfPop.fPopCalendar(this);return false;"
I am definitely more designer than programmer. Not sure if this possible, If it is then I am definitely getting the syntax wrong. I'm trying to pull array data as such:
var carouselC2R1Array = new Array(500, 4, 0);
var currentSilo = 2;
var currentImg = 1;
carouselWidth = "carouselC"+currentSilo+"R"+currentImg+"Array"[0];
carouselMaxImages = "carouselC"+currentSilo+"R"+currentImg+"Array"[1];
carouselCurrentImg = "carouselC"+currentSilo+"R"+currentImg+"Array"[2];
But instead of returning the correct data I get this:
carouselWidth = c
carouselMaxImages = a
carouselCurrentImg = r
Is there any function or property for finding out the size of the first (or for that matter any) dimension of a multidimensional array?EDIT:There seems to be no such functionality, I found a solution that does not require it. If anyone is reading this for the same reason; it needs to be scripted.

View 2 Replies View RelatedThe problem is that it keeps returning a value of 0 every loop. When tested in Internet Explorer, FireFox and Google Chrome, it works just fine, returning values as it should (in this case the values of 32, 36, 35, 36). However, like i said, Safri returns 0, 0, 0, 0.
Crazy thing is, before it calls the checkArray() function, i check to make sure its sending the correct number and it does, so its something to do with the .length part since i did a check on that and that's where its coming up with the 0's.
var aryItems = new Array();
function add2Array(theName){aryItems[aryItems.length] = theName;}

Ok the setup is basically this. The user selects a option in a drop down field, whatever they select through javscript additional records are populated in a second select field. This second select field allows for multiple selections, however I am submitting the form to a php script and I want to capture the multiple selections in the second select field. To do that for php I need to turn the field into an array so I have to add the brackets, [], to the name of the select field.
In php you can name the field like so:
Code:
<select name="fld[]" size="1">
The problem is in the js function when I give it a field name with [] the script doesnt work. Here is the js function:
Code:
function channelform(select_value) {
IntPath = document.channel_form.cid[]
TheOptions = IntPath.options.length
[Code]..
You can see the [] for the cid field name. Whenever I add that to the field name the js script is broken. How do I get it to work so that I can pass an array to php when the form submits?
How to get a number to update realtime on a site? What I'm looking for is used on the following website:

I am working on a very simple code to determine the highest value from an array and also use parallel arrays.
The problem I am having is, when I try to invoke the parallel array namesArray it returns undefined.
I have coded the function so it can be used to find the highest value in more arrays as this is only the beginning of my code. Im not sure if this is what is causing the problems but I have a feeling it is code...
