JavaScript - How Do I Sort Multi-dimension Array But From 1 To Length Not 0 To Length

Overview:
Order entry project. I am using an iFrame to pull external forms that I can not change. Once our employee enters in the information and submits I would like to redirect the existing window to a new page.

I've tried many variations of:
Code:

<script type='text/javascript'> 
function iHistory() {
var hist=history.length;
if (hist>1)
	{
		parent.window.location = "orderentry.php";
	}
}
</script>

Since I have no control of the external form I have been using OnLoad() in the iFrame tag to call iHistory(). The script works great unless the browser history is >1 If possible, I would like to also setup like a 5 or 10 second delay so the employee can see the framed confirmation page before redirect.

So the function needs to check current history.length, when that changes delay 5-10 seconds and redirect parent window to orderentry.php

function checkValidFormInput() {

if (document.getElementsByName('customerName').value != '') {
document.getElementById('customerNameImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">';
} else {
document.getElementById('customerNameImg').innerHTML = '<img alt="Invalid" src="images/redX.png">';
}

if (document.getElementsByName('customerEmail').length > 0) {
document.getElementById('customerEmailImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">';
} else {
document.getElementById('customerEmailImg').innerHTML = '<img alt="Invalid" src="images/redX.png">';
}

}

Ok

I have a textarea field that is validated by Js, this textarea can and will contain the newline character

Code:

\n

so I validate in JS Code:

if(textareaname.value.length < 200)

this hten goes through to my php where i also check before I place in to the Database using MYSQL

Code:

if( strlen($_POST['textareaname']) < 200 )

but my php is giving me a different string length from my javascript.

It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.

I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.

Any ideas? Any suggestions as to how I can make php and javascript treat a newline as the same amount of characters?

Thanks in advance.

I want to use the new keyword to instantiate an object. The catch is I want to pass in variable length arguments.

Given:
Code:

function Foo () {
  this.args = Array.prototype.join.call (arguments);
}

var args = ["arg0", "arg1", "arg2"];

The following don't work (though I understand why):
Code:

new Foo.apply (null, args);

new (Foo.apply (null, args));

(new Foo).apply (null, args);

Any ideas on how to do what I want without modifying Foo's source code?

I'm trying to figure out how to add a length paramater to this function. Not quite sure how to do it. here's what I tried:

Code:

var phone = document.getElementById('phone');

if(isNumericdashes(phone, "Please enter a valid phone number")){
									return true;
									}

function isNumericdashes(elem, helperMsg){
	var numericExpression = /^[0-9\(\)-]+$/;
	if(elem.value.match(numericExpression) &&(elem.length > 9)){
		return true;
	}else{
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

Hi,
I have added an validation script for Pizza menu. Validation working fine in all browsers except IE.
When I working in IE8 it throws an error "length is null or not an object error in IE8".
Please help me. See Java script code below:
<script>
function UnCheckRadios(radioButtonGroupName)
{

var formName = "frmOrder";
var form = document.forms[formName];
alert(form);
var noOfRadioButtons=form[radioButtonGroupName].length;
for(var x=0;x<noOfRadioButtons;x++)
{
chk=form[radioButtonGroupName]
.checked=false;

}
}
</script>

PHP code:
<input type="radio" id="<?=$subitem['subgroup_id'];?>_comboleft" name="<?=$subitem['subgroup_id'];?>_comboleft" value="<?=$subitem['id'];?>:Left Side" onclick="UnCheckRadios('<?=$subitem["subgroup_id"];?>_combowhole');">

I write code using ext js,openlayers and GeoExt for measuring length and area
,it is working inside inside of india in the world map but this measure tool is not working outside of india in the world map.

My code for Measure length:
To Load map:
var projWGS84 = new OpenLayers.Projection("EPSG:4326");
var projSphericalMercator = new OpenLayers.Projection("EPSG:900913");
var bounds = new OpenLayers.Bounds(68.137, 6.783, 97.336, 37.086);
bounds.transform(projWGS84, projSphericalMercator);
map.maxExtent = bounds;
var gphy = new OpenLayers.Layer.Google("Google Street", {
'sphericalMercator':true
//maxExtent: new OpenLayers.Bounds(-20037508, -20037508,20037508, 20037508)

}
);
var osmLayer = new OpenLayers.Layer.OSM();

// Add the background images via WMS


// Add the background images via WMS

//map.addLayer(bglayer);
// map.addControl(new OpenLayers.Control.MousePosition());
map.addLayers([gphy, osmLayer]);

Measure Length:
Measure = new Ext.SplitButton({
text:"Measure",
iconCls:"icon-measure-length",
toggleGroup:"navigate",
group: "navigate",
enableToggle:true,
allowDepress:false,
handler: function(button, event) {
// allowDepress should deal with this first condition
if(!button.pressed) {
button.toggle();
} else {
button.menu.items.itemAt(activeIndex).setChecked(t rue);
}
},
listeners: {
toggle: function(button, pressed) {
// toggleGroup should handle this
if(!pressed) {
button.menu.items.each(function(i) {
i.setChecked(false);
});
}
},
render: function(button) {
// toggleGroup should handle this
Ext.ButtonToggleMgr.register(button);
}
},
menu: new Ext.menu.Menu({
items: [
new Ext.menu.CheckItem(
new GeoExt.Action({
text: "Length",
toggleGroup:"navigate",
iconCls:"icon-measure-length",
group: "navigate",
enableToggle:true,
allowDepress:false,
map: map,
control: new OpenLayers.Control.Measure(OpenLayers.Handler.Path , {
eventListeners: {
measu function(evt) {
Ext.MessageBox.show({

title: 'Line length :',
buttons: Ext.MessageBox.OK,
width:200,
msg:"Line Length: " + evt.measure.toFixed(2) + " " + evt.units

});
}
}
})

})
)

}
})

})
)
]
})
})

How can I call a function in javascript like:

Code:

var x = string.Length

???

and not like:
Code:

var x = Length(string);

(just for arguments sake)
(Also please don't suggest JQuery, I'm doing this to learn!)

Thanks!

Hi all,

I have a free script I have downloaded and I can't figure out how to edit it so that I can change the color of the text to whatever I want it to be and also so that the length of the scrolling text (I am not sure if scrolling is the right term) can be changed.

For some reason the text does not go all the way to the end of the page on the right it stops quite a way before.

Here is the code:

Code:

<script language="JavaScript1.2">
<!--

/*
Typing Scroller
For full source code, usage terms, and 100s more scripts, visit http://dynamicdrive.com
*/

//Secify scroller contents
var line=new Array()
line[1]="Testing testing one to three and you can test some more."
line[2]="Always testing always testing"
line[3]="Trying to test some more and some more again"
line[4]="second to last bit of testing."
line[5]="Testing text that is just testing one more time"

//Specify font size for scoller
var ts_fontsize="13px"

//--Don't edit below this line

var longestmessage=1
for (i=2;i<line.length;i++){
if (line[i].length>line[longestmessage].length)
longestmessage=i
}

//Auto set scroller width
var tscroller_width=line[longestmessage].length

lines=line.length-1 //--Number of lines

//if IE 4+ or NS6
if (document.all||document.getElementById){
document.write('<form name="bannerform">')
document.write('<input type="text" name="banner" size="'+tscroller_width+'"')
document.write('  style="background-color: '+document.bgColor+'; color: '+document.body.text+'; font-family: arial; font-size: '+ts_fontsize+'; font-weight:bold; border: medium none" onfocus="blur()">')
document.write('</form>')
}

temp=""
nextchar=-1;
nextline=1;
cursor=""
function animate(){
if (temp==line[nextline] & temp.length==line[nextline].length & nextline!=lines){
nextline++;
nextchar=-1;
document.bannerform.banner.value=temp;
temp="";
setTimeout("nextstep()",1000)}
else if (nextline==lines & temp==line[nextline] & temp.length==line[nextline].length){
nextline=1;
nextchar=-1;
document.bannerform.banner.value=temp;
temp="";
setTimeout("nextstep()",1000)}
else{
nextstep()}}

function nextstep(){

if (cursor==""){
cursor=""}
else if (cursor==""){
cursor=""}
else if (cursor==""){
cursor=""}
else if (cursor==""){
cursor=""}


nextchar++;
temp+=line[nextline].charAt(nextchar);
document.bannerform.banner.value=temp+cursor
setTimeout("animate()",25)}

//if IE 4+ or NS6
if (document.all||document.getElementById)
window.onload=animate
// -->
</script>

I have been trying to figure this out for about 2 hours but since I am a 100% novice with javascript I have not got very far.

Any help would be gratefully recieved.

Hey I was just wondering how I could do this...

I currently have this
Code:

<span id="span_1">Title</span>

What I want to know is if the span is something like 240px in width how can I make it so if the text inside the span tag is to long and puts the text onto a second line how can i make a cut off point in the text to stop the text moving to a new line and adding '...' if the text is to long??

Hi,
I started getting a wierd problem with my jscript program.
Here im using jscript for client-side validation and upon email field submission,im getting undefined value with an error saying "length is null or not an object".
All the values of fields prior to that are being obtained properly.
Please help me out of this crisis

I have a string of text, and starting from a particular spot (known to be a number), I want to find the length of that number.

Here's what I have: Code:

...

var start = [...predetermined...]
var end = 0;
while (!isNaN(sourceCode.charAt(start + end))){
   endCurrent++;
}
var myNum = sourceCode.substr(start, end) * 1;

So let's say var sourceCode = "alkdjabjasdsdf-53 dnalsdb..."; , startCurrent will already be at the "5" and I want to be able to extract the "53". What I have works, but it seems cumbersome...

Any advice?

Hello,

When I run the following code, the .Length function returns "undefined." Please help! This is driving me crazy.

Code:

		var strTest = 'test';
		alert(strTest.Length);

Using the typeof function, I know that JS is treating the variable as a string. Any suggestions?

I 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. Can you tell me why numSubs.length keeps getting set to 0 when it should be 1 or two?

Code:

 var subs = "sub" + (i + 1);
   var numSubs = document.getElementsByName(subs);  
   alert(numSubs.length);
      for(j=0; j < numSubs.length; j++)
	  {
	   alert();
	   toc.innerHTML += "<li>" + numSubs.item(j).innerHTML + "</li>";
	  }

this is the body of the html
Code:

<h1>Boolean Algebra</h1>
     <h2>Fundamental Boolean functions</h2>
         <h3 name = "sub1">Boolean Wrapper Class</h3>
         <h3 name = "sub1">Boolean Computations</h3>
      <h2>Computational Completeness</h2>
          <h3 name = "sub2">Calculating Machanics</h3>
      <h2>Identities of Boolean algebra</h2>
          <h3 name = "sub3">NAND and NOR</h3>
      <h2>NAND and NOR</h2>

I need to have an online submission form, which accepts text for print adverts.

Here is my problem:

Whereas with Twitter, you are limited to 140 characters as the output is digital, with print the overall width of text is vital if it has to fit within a given space.

Are there any javascript software libraries available that can calculate the printed length? Preferably as the user types. This assumes that the font, font-size and kerning are known. (I do not want to use the 'Courier' font)

We will have to write this in-house unless there is something available on the internets (I'm possibly not the first person to come up against this)

Can anyone help?
