JavaScript - Check To See Multiple Concurrent Characters

Hi,

Can someone tell me what I am doing wrong. Script works on the first attachment but not the other two?

Code:

<script type="text/javascript" language="JavaScript"><!--
function ExtensionsOkay() {
var extension = new Array();
var fieldvalue = new Array();
fieldvalue[0] = document.customApp.attachment_1.value;
fieldvalue[1] = document.customApp.attachment_2.value;
fieldvalue[2] = document.customApp.attachment_3.value;
extension[0] = ".doc";
extension[1] = ".docx";
extension[2] = ".txt";
extension[3] = ".pdf";


// No other customization needed.
for(var f = 0; f < fieldvalue.length; f++) {
var thisext = fieldvalue[f].substr(fieldvalue[f].lastIndexOf('.'));
for(var i = 0; i < extension.length; i++) {
	if(thisext == extension[i]) { return true; }
	}
alert("Your upload field " + f + " contains an unapproved file name.");
return false;
}
}
//--></script>

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

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?

Need to know how to define hex characters for the following;

var x = hex value

var y new Array(hex value, hex value, etc)

document.write(hex value)

I'm trying to figure out the proper way to correctly get each full-formation of encoded html (of Unicode), so that I could assign each HTML encoding with its each Unicode characters


HTML Encoded Unicode:

नया नेपाल


I want to retrieve each encoded HTML and assign them into array like this

Code:

    var my_array = new Array();
    my_array [0] = "2344";
    my_array [1] = "2351";
    my_array [2] = "2366";
    my_array [3] = "2344";
    my_array [4] = "2375";
    my_array [5] = "2346";
    my_array [6] = "2366";
    my_array [7] = "2354";

Thanks in Advance for helps

I am using the below javascript to verify a text input box but I would also like to require atleast 3 characters being entered before allowing the user to search. How do I accomplish that? Thanks in advance!

Code:

<script language="JavaScript">
<!--

/***********************************************
* Required field(s) validation v1.10- By NavSurf
* Visit Nav Surf at http://navsurf.com
* Visit http://www.dynamicdrive.com/ for full source code
***********************************************/

function formCheck(formobj){
	// Enter name of mandatory fields
	var fieldRequired = Array("words");
	// Enter field description to appear in the dialog box
	var fieldDescription = Array("Company Name");
	// dialog message
	var alertMsg = "Please complete the following fields:\n";
	
	var l_Msg = alertMsg.length;
	
	for (var i = 0; i < fieldRequired.length; i++){
		var obj = formobj.elements[fieldRequired[i]];
		if (obj){
			switch(obj.type){
			case "select-one":
				if (obj.selectedIndex == -1 || obj.options[obj.selectedIndex].text == ""){
					alertMsg += " - " + fieldDescription[i] + "\n";
				}
				break;
			case "select-multiple":
				if (obj.selectedIndex == -1){
					alertMsg += " - " + fieldDescription[i] + "\n";

				if (obj.value == "" || obj.value == null){
					alertMsg += " - " + fieldDescription[i] + "\n";

						blnchecked = true;

					alertMsg += " - " + fieldDescription[i] + "\n";
				}
			}

	}

	if (alertMsg.length == l_Msg){
		return true;
	}else{
		alert(alertMsg);
		return false;
	}

How can to obtain length of string variable, for example if I have:

var msg = 'hello world!';

Does it exist a method to count string characters?

So, I have this javasript code in HEAD

<script type="text/javascript">
<!--
function validateThis(registerForm) {
if (registerForm.firstname.value == 'Name') {
alert("Oops");
return false;
}
else {
return true;
}
}
//-->
</script>

with this form in BODY

<form action="register.php" method="post" name="registerForm" onSubmit="return validateThis(this)">
<input type="text" value="Name" onclick="if(this.value=='Name'){this.value=''}" onblur="if(this.value==''){this.value='Name'}" name="firstname">
</form>

and I want to put a text with Greek characters instead of value "Name". I tried it and the "function validateThis" didn't work. The form just passes it and returns true. I tried also hexadecimal code,HTML entities and numeric HTML entities and didn't work either. What I should I do? Thank you in advance!

Can some one help me, I want to replace the characters from a string and I have tried with this script:

Code:

var v5=form.description.value.replace(/#/, "%23");

But it only changes the first character from the string.

Turning #### into %23### but I want them all transformed.

I have a textbox ( I am using asp.net ). I want to use that textarea as rich text box. The text in textarea is submitted to database and then displayed. So, I can use <b><u> tags, but I want to use smileys too. I need a simple code for it.

My logic is simple...,

Whatever text is written inside the textarea is first read and when a group of specific character like Code:

 " :) ;) x-("

are found, that characters should be colored to red . So, a Code:

:)

will appear as Code:

 :) 

.

This logic is simple but I am new to javascript programming, it cant implement it.
Can a provide a javascript for this, or if you have better but simple code plz let me know.

Hi,

So I've got an array called questions_raw

Code:

questions raw = [
["<Q1> Question",
    "choice1","choice2", "choice3"],
["<Q2> Question",
    "choice1","choice2", "choice3"],
...
]

And I want to list all of the questions, but not the choices/answers. So far, I've managed to list just the questions, but because another function randomly sorts them, I need to sort them back into numerical order for a separate function (displaying the questions)

I use characters (>,^) at the front to separate them into different answer types (just to explain the code)

I try this to cut each string down so that they can be sorted numerically/alphebetically -

Code:

function linearlist()
{
var list = [];
var tempStr = "";
for (var l = 0; l < 145; l++)
{
	tempStr = questions_raw[l][0];
    list[l] = tempStr;
}

if (list.charAt(0)== " " )  list = list.substring(3) ;
if (list.charAt(0)== ">" )  list = list.substring(3) ;
if (list.charAt(0)== "^" )  list = list.substring(3) ;
var sorted = list.sort();

document.Qtext2form.Qtext2.value = sorted.join("\n");
}

But it doesn't like it - because "it has no method charAt"

Any idea what i'm missing? Is it just that you have to put the [l] in every time you call a variable?

Cheers

My credit card processing service will only accept English characters. I need to detect entries in the form that are using non English characters.

Is there a way in Javascript to create a function to force a string to UTF-8? My idea is to do something like

function forceUTF8(X){
Y = ???? X;
return Y;
}

if ( stringA != forceUTF8(stringA) alert ("You must use English Characters");

Code:

<script type="text/javascript" src="external.php?type=js"></script> 
<script language="" type="text/javascript">
<!--
for (x = 0; x < 10; x++)
{
document.writeln("<a href=\"showthread.php?t="+threads[x].threadid+"\">"+threads[x].title+"</a>, ");
}
//-->
</script>

My code will display 10 posts, however at the very end it will display an extra ", " which bugs me. How can I strip those last two characters.

First of all thanks for all the help you are providing.

I am looking to alert a user if they type in an character that I am going to not allow for their input box

Code:

function IsExc (str){
var AllChr = "~ # $ % ^ { } [ ] ' ,";
var AC= AllChr.split(" ");
var SC = 0;
   for (SC=0; SC <= AC.length; SC++){
	var ACS = AC[SC];
	if (str.search(ACS)  >0 ) alert ('Cannot use the characters' + AllChr )
   }
}

For reasons I don't understand the code will not work
