JavaScript - Check For Equivalance To Multiple Values?

I have the following script that currently returns 4 of the same images. I can't wrap my head around how to get it to return 4 random images (out of the 7 in this example)? Also the links aren't working?

---
Code:

var imagenumber = 7 ;
var randomnumber = Math.random() ;
var rand1 = Math.round( (imagenumber-1) * randomnumber) + 1;

images= new Array
images[1] = "image1.jpg"
images[2] = "image2.jpg"
images[3] = "image3.jpg"
images[4] = "image4.jpg"
images[5] = "image5.jpg"
images[6] = "image6.jpg"
images[7] = "image7.jpg"
var image = images[rand1]

links= new Array
links[1] = "link1.html"
links[2] = "link2.html"
links[3] = "link3.html"
links[4] = "link4.html"
links[5] = "link5.html"
links[6] = "link6.html"
links[7] = "link7.html"
var link = links[rand1]

document.write('<div id="image-1"><a href="' + link + '"><img src="' + image + '"></a></div><div id="image-2"><a href="' + link + '"><img src="' + image + '"></a></div><div id="image-3"><a href="' + link + '"><img src="' + image + '" border="0"></a></div><div id="image-4"><a href="' + link + '"><img src="' + image + '"></a></div>')

Hi,

I am setting up an email form & i would like the subject field to hold multiple values, the forrm will be something like this:

Name:Mr A
Date: 01/01/01
Reason:Football

I want the form to send an email without opening an email client & I would like the subject field to look like this:

Subject: Mr A, 01/01/01, Football

or

Subject Mr A - 01/01/01 - Football

Can anyone tell me if this is possible, if if is can you please point me in the right direction.

Thanks

Hello there. I'm having trouble with cookies. I have a bunch of links that when clicked on, create a cookie. For each link I need to be able to save that cookie value to the main cookie name.

Here is the click function I'm using to create the cookie:

$j('a.createCookie').click(function(e) {

var cookieName = "InsightsCookie";

var cookieValue = $j(this).attr("id");

$j.cookie(cookieName, cookieValue, {expires: 365, path: '/'});
});

The end result would be "InsightsCookie: cookieValue, cookieValue, cookieValue" - where each link clicked on would add a value to InsightsCookie.

Any help would be much appreciated.

Hey CF.

I'm not great with JS, but I'm trying to build something pretty simple and even that's out of my league. I have a layout with multiple fields that need to be filled randomly from an array on click.

I have an array with a bit of jQuery that randomly reloads one field on click, but I need multiple fields filled at once from the same item in the array.

Code is below. I grabbed it from a tutorial somewhere, and have made some modifications.

Code:

<Script>
$(document).ready( function() {
    var foodArray = [
        '1',
        '2',
        '3',
        '4',
        '5'
    ];
    $('.foodtype').loadText( foodArray, 10000 ); // ( array, interval )
});
// custom jquery plugin loadText()
$.fn.loadText = function( foodArray, interval ) {
    return this.each( function() {
        var obj = $(this);
        obj.fadeOut( 'slow', function() {
            obj.empty().html( random_array( foodArray ) );
            obj.fadeIn( 'slow' );
        });
        timeOut = setTimeout( function(){ obj.loadText( foodArray, interval )}, interval );
        // reload random text (if not animated) -- entirely optional, can be removed, along with the reload link above (<a href="javascript:;" id="text-reload"><em>randomize</em></a>)
        $("#text-reload").click( function(){
            if( !obj.is(':animated') ) { clearTimeout( timeOut ); obj.loadText( foodArray, interval );} // animation check prevents "too much recursion" error in jQuery
        });
    });
}
//public function
function random_array( aArray ) {
    var rand = Math.floor( Math.random() * aArray.length + aArray.length );
    var randArray = aArray[ rand - aArray.length ];
    return randArray;
}

</script>

That outputs one of the array items into a <span class="foodtype">. What I need is another value next to say "1", eg '1, Blue' and print "Blue" to another span.

Can anyone help?

The other issue I have is the divs are snap resizing, is there a way set them to animate smoothly? The total height will be variable depending on the combinations that display.

Cheers guys, hope someone can help.

}

print "</table>";
}

this is part of a php searchengine script that i wrote to retrieve data from a database and as you can see the last column that is g contains a link which when clicked takes the user to the second php script which retrieves additional information of that entry, but this is done for only single entries so as you can see i introduced checkboxes so that the user can check any number of checkboxes and retrieve information as per their wish

now to do this i created a <input type=text where i want the value of these checkboxes i.e. $id to be posted in a delimited format so that the user can then click the corresponding button and retrieve the information this is the code

<div id="floatMenu">
<ul class="menu1">
<center><li><form name="senddata" method="POST" action="http://localhost/retrieve.php" style="display:inline;"><input id="fasta" type="text" class="multitext"><input name="Fasta" type="Submit" value="Retrieve Fasta"></form>

this is a css floating menu....so far so good....everything went fine....
after this i had to write a javascript to do this and i've been stuck there searching forums for the last 4 days!

this is the javascript i found from somewhere which came close to doing wht i wanted it to do

window.onload = function () {
var cb = document.getElementById('check');
var fasta = document.getElementById('fasta');
cb.onclick = function () {fasta.value = cb.value + ",";
};};

this script only sends the value of the first checkbox in the table, the others are not found by it, mind you its not the first checkbox selected its the first checkbox that is present in the table

how can i resolve this problem so that even if i have n number of checkboxes in my table, if the user chooses to do so they can retrieve n number of information....please help i've almost lost hope in this!

hello everybody!
this is my first atempt in writing javascript and i have a problem which I have no idea how to solve.

I want to take the values from several dropdown forms and make some calculations whit those in order to display a number. Unfortunately the script responts in a way that i cannot identify what is happening. this is a shorten example of my script.

Code:

<html>
<head>
<script type="text/javascript">



function calcul()
{


	var pcno = document.plithospc.listplpc.value;
	var ndno = document.plithosnd.listplnd.value;
	var hotline = document.hotlform.listhotl.value;

	var sumhotline = 0;

if (hotline == 2)
	{
		sumhotline = 8*(1+0.5*pcno) + 2*(1+0.5*ndno);
	}
	else if (hotline == 3)
	{
		sumhotline = 16*(1+0.5*pcno) + 4*(1+0.5*pcno);
	}
	else 
	{
		sumhotline = 0;
	}

document.write(sumhotline);

</script>

</head>
<body>


<FORM NAME="plithospc">
<SELECT NAME="listplpc">
<OPTION SELECTED="SELECTED" VALUE=0>choose one</OPTION>
<OPTION VALUE=1>-1-</OPTION>
<OPTION VALUE=2>-2-</OPTION>
<OPTION VALUE=3>-3-</OPTION>
</SELECT>

<FORM NAME="plithosnd">
<SELECT NAME="listplnd">

<OPTION VALUE=2>second selection</OPTION>
<OPTION VALUE=3>third selection</OPTION>
</SELECT>

<button type="button" onclick="calcul()">click me</button>

does anyone knows how to fix this?
thanks in advance

Hi gud mng,

I have one problem...

How to process textbox values/ call textbox values in JS through a Java program.
My text box values are dates. I have to process these dates.

Like in online banking we select day to know our transactions. After submitting we get results. remember my files are in my directory only. No need of database.

My files are look like 20100929, 20100930, 20101001

In my coding, ys, ms, ds represents year starting, month starting, starting day...
ye, me, de represents end...

start,end gives file names in the format of yyyymmdd

now i want to process files from 20100101 to 20100930

means from date is 2010/01/01 and to date is 2010/09/30

if i press submit button the files from 20100101 to 20100930 are processes

here ys=2010 ms=01 ds =01 and ye=2010 me=09 de= 30

For this how do i call these textbox values (from date text box and todate) to another program (java)

Thanks in advance.

Hi guys.

I'm working a bunch of pre existing code on a CMS. Just after a quick fix. Doing a show/hide thing on a particular div somewhere on the page depending if a checkbox is ticked or not.

Currently there is 3 checkboxes that are dynamically added through the CMS.

Here's simplified version of the form:

Code:

<form id="simplesearch" name="simplesearch">
<input type="checkbox"   onclick='showhidefield(this.value)' name="meta_data_array_search_criteria[custom_profile_type][]" value="5"  class="input-checkboxes" />
<input type="checkbox"   onclick='showhidefield(this.value)' name="meta_data_array_search_criteria[custom_profile_type][]" value="4"  class="input-checkboxes" />
</form>

And here's the javascript I was playing with.
Code:

function showhidefield(id)
{
   if(document.simplesearch.meta_data_array_search_criteria[custom_profile_type][''].checked) {
      document.getElementById("profile_fields_wrapper_" + id).style.visibility = "visible";
   }
   else
   {
      document.getElementById("profile_fields_wrapper_" + id).style.visibility = "hidden";
   }
}

Problem I'm having is how do i do a check to see if those checkboxes are checked in the javascript with those name arrays? How do i separate them? 'm guessing I have to loop through them or something?Hopefully that make senses - it's late here and I'm losing the plot Any pointers would be gratefully welcomed

I have a bunch of checkboxes like below that the user can check some or all and click the button and see the values of all the selected checkboxes. How can I do that?

Code:

<script>
function alertValues(){


}
</script>


<input type="checkbox"  class ="normal2" value="131971" name="list[]" >
<input type="checkbox"  class ="normal2" value="131973" name="list[]" >
<input type="checkbox"  class ="normal2" value="131975" name="list[]" >
<input type="checkbox"  class ="normal2" value="131977" name="list[]" >

<input type="button" onClick="alertValues()"

Hi,
What's a good way/ideal data structure to achieve this?

The objective of the code/function is to map user-inputted strings into a pair of specific, hard-coded strings. For example, say the user types "firefox" or "ff", or "fx". The output would be the pair ["browser", "mozilla"], for example.

I'm currently using a multidimensional array, but it feels inefficient and I'm having trouble mapping an arbitrary number of inputs into 2 outputs.

Code:

var strings = [ ["input1", "output1a"],
                ["input2", "output1a"],
                ["input3", "output1a"],
                ["input1", "output1b"],
                ["input2", "output1b"],
                ["input3", "output1b"]
              ];

How should I map the elements ["input1", "input2", "input3"] => ["output1a", "output1b"] ?

Another method I used previously was a massive switch statement. This fulfills my needs, but I'm not sure about the efficiency (though if I remember correctly, switch statements become more efficient as size grows, since it uses a hash table?).

Code:

switch (input) {
    case "ff": case "firefox": case "fx" : case "ffox":
        return ["browser", "mozilla"];
    case "ie": case "internet explorer":
        return ["browser", "microsoft"];
    ...
}

Hi,

I hope someone can help me. I'll be honest and say I don't know much about javascript, but am fairly comfortable in html.

I am building a website that will have multiple image swaps on multiple pages. I am building this in wordpress, and I'm guessing that means my approach will be different than if I wasn't using wordpress.

Here's how one page would work: There are 10 images shown. 1,2,3,4,5,6,7,8,9,10. When number 1 is clicked on, I want a new image - 1a. When 2 is clicked on, 2a. So there are 20 different images in all on a given page.

Also, I want the user to be able to click on the image again to restore the original image. I would prefer onclick to onmouseover.

There will be literally dozens of pages like this on the site, managed by wordpress, so hundreds of images to swap. Basically the first image is a question - the second image is the answer.

Is this possible?
