Check Last 15 Characters Of A String For A Space/tag?
Jun 27, 2011
So I want to be able to check the last 15 characters of a string for either <br /> or a space. I know how to do this with PHP but I have no clue how to do this with Javascript and Google is failing me. Could someone point me in the right direction?
Example string: var string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
I'm assuming this will be done with lastIndexOf but I do not know how to do it. So to reiterate, I want to check to see if either a space exists, or <br />, delete everything after that, and return the string. So the output of the example string would be...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo

This may seem like an odd question but I was wondering if there was a way to use javascript to dynamically inter space characters in a string with other characters.
Basically i would want to take this:
"This is a string"
and replace it with this:
"T.h.i.s. .i.s. .a. .s.t.r.i.n.g"
I know it seems strange but I have my reasons

I am trying to check for Arabic characters in a string using Regular expressions. This should return true, as the string in the str variable is indeed Arabic character. But it returns false.

I'm trying to write a function that takes a word and adds a space between each letter e.g space becomes s p a c e. I have written below but when I call the function it says the argument is not defined.
Code:
function insertSpaces(string){
var currentCharacter;
var resultString;
resultString = ''
//a line to loop through each charcther in the string agument
for (var position = 0; position < string.length; position =
position + 1){
// set current characther as the first charcter in the string and add a space
currentCharacter = (string.charAt(position) + ' ')
//store the currentcharcter and add followng characthers
resultString = currentCharacter + resultString
} return resultString
}

With the code I had to acknowledge nothing had been inserted,(that is, still spaces, it was working. When I added the code to only accept alpha chars etc., I inserted numbers, nothing worked, with no error message. Would you, or can I send the whole code through for the form. I noticed that the form tags had been changed so I altered them as well according to your message.

I am not able to calculate the offsetwidth of the element which contains extra space in between the characters.for ex. if the element contains "A A" as a innerHTML value - if we calculate offsetwidth as 29 and also if the element contains "A A" value again I am getting the same offsetwidth as 29.While calculating the offsetwidth it is not calculating the empty space.May I know how to calculate the offsetwidth with the empty space because I need to insert the ellipsis (...) if it exceeds original width?
Code snipet
function fitStringToWidth(title,width,className) {
var span = document.createElement("span");
span.className="titleBar-Title-1";
[Code]....

I am looking for a function that will add spaces in a string in a certain manner:
tmpStr: 123456789123 (always 12 digits)
the desired outcome is: 123 456 78 91 23
Do anyone of you have a neat fuction for that? I found one question in this forum [URL]... but since I do have a different interval for my spaces I have not been able to make it work.

I have used the script below to split a field down at commas and then
created a new string
This works but after the first item there is a space where the comma used to
be, is there any way I can remove this?
<script language="javascript">
var devText="<%=(houses.Fields.Item("location").Value)%>";
function getDevelopments() {
var input = devText.split(",");
var input2 = new String();
for (var i = 0; i<input.length; i++) {
input2 += "<a
href='home_template.asp?id=<%=(houses.Fields.Item('id').Value)%>&titleofdeve
lopment=" + input[i] + "'>" + input[i] + "</a>" +"<br>";
} document.all("dev").innerHTML = input2;
}
</script>

I have an input box with a 'did you mean' box that pops up under it, and it pulls it's results from another php page, however when a term with a space in it, such as "I am" vs. "Im" is entered, it stops working. This is the code I'm using to pull the results. So I made a added a simple string replace to change each space into '+';
search = $('#search').val().replace(' ','+');
search.keyup(function() {
results.load('results.php?q=' + search);
});
But for some reason it is only changing the first space into a '+'; so for example: "Hello how are you" = "Hello+how are you". But I need it to change to "Hello+how+are+you";

am doing a check on my fields, so that they only contain certain characters and numbers. var validEntry = /^[a-zA-Z0-9@$&"]+/; but this also captures a space in between words as an error. can somebody please tell me on how to avoid this.

I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

Let me preface this with the usual disclaimer: I am new to this and have only been programming with Javascript, PHP for about 2 weeks now and have been lucky enough to have resolved the issues I have encountered. This one however is puzzling to me.
I have a HTML form created that collects member information. It calls, on submit, a confirmation page that lists all the data fields entered. This all works great. However, when I then post the variables from the first html form page from my second confirmation html page to my PHP script, using document.write with input type=hidden and inserting the address variable into the value field, the Javascript only passes this variable up to the first space. It is the only variable I pass that has a space in it.
I have verified that the variable does indeed contain the whole address and I have also verified when I execute the following: document.write ('<input type="hidden" name="address1" value='+address_1+'>');
the address_1 parameter passed to the php script only passes the string up to the first space.
I even tried to put fixed text in there instead of a variable (e.g.)
document.write ('<input type="hidden" name="address1" value="555 Drury Lane" >');
and it still only passes the string up to the first space (555).
I show the variable address_1 on my confirmation page and it shows the entire string.
I checked what was being passed and it seems that the Javascript is the culprit (or more likely the Javascript creator - me)
All my other variables (which don't have spaces) pass to the php script with no problems.

I am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?

So I've got an array called questions_raw
questions raw = [
["<Q1> Question",
"choice1","choice2", "choice3"],
["<Q2> Question",
[Code]....
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 -
function linearlist()
{
var list = [];
var tempStr = "";
[Code]....
But it doesn't like it - because "it has no method charAt"
Is it just that you have to put the [l] in every time you call a variable?

I have a JavaScript string. I want to replace all consecutive
occurrences of whitespace characters like spaces, tabs, newlines, and
form feeds with another string.
For example, say I have a string consisting of:
-- 3 spaces
-- The characters "hello"
-- 2 newline (
) characters
-- The characters "goodbye"
-- 5 spaces
After applying some sort of regular expression to replace consecutive
occurrences of whitespace chars with the string "X", the string should
consist of the following:
-- The character "X"
-- The characters "hello"
-- The character "X"
-- The characters "goodbye"
-- The character "X"
How could I do this using regular expressions? I'm quite familiar with
JavaScript but don't know anything about regular expressions or using
them in JavaScript, so please show me step-by-step how it's done.
