Is it possible to break apart a string into characters, be it a word or a sentence, and store each individual character in an array?
View 11 Replies View RelatedHow I would remove characters from a string if they are present?
For example lets say I wanted to remove c:/fakepath/ from the string c:/fakepath/DSF102.jpg and just leave the DSF102.jpg how would I got about this?
I would like to check if a string is a valid zip code via Javascript.
Length and existents are already checked.
How can I find out if the string contains characters other than numbers?
Example: 834F7
schould be false since it countains an F character
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.
I am running a search on my web site which uses jQuery to take the search terms and build up a URL based on them. For example, if someone searches for "chair" my URL will be appended with /chair/. However, if someone searches for something which is two words, for example "chair covers" I need the space in between to be replaced by a "+" sign so the URL will now be appended with /chair+covers/ I'm not sure if it is possible to string replace in jQuery?
Here is my current code:
function sendSearchInput(whichelement,hiddeninput,formid) {
hval = $("#"+hiddeninput).val();
$("#"+formid).submit(function() {
if ($("input:#"+whichelement).val() != hval) {
var searchval = $("#"+whichelement).val().toLowerCase();
$("#"+formid).attr("action","retail/search/"+searchval+"/");
return true;
}
$("input:#"+whichelement).focus();
return false;
});}
This will basically check that the form is not the default value (specified in the hidden field "hval") and then change the search term to lowercase and append the URK using "attr". I have tried a couple of methods including
var test = searchval.text().replace(' ','+');
And then trying to alert "test" to check it but the function just simply doesn't work.
I want to extract the characters other than alphabets (a-z and A-Z), numbers (0-9) and hyphen( - ) from a string. Is there any way for doing this?
View 2 Replies View RelatedSo 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

Can anyone tell me how to escape the special characters(like &,^,%,$ etc) in a string using Javascript?

I need to declare a variable (astString) and initialise it with a string of asterisks. astString needs to be the same length as another variable (otherString). otherString changes it value regularly so I think I need to use the .length property in some way but I can't see how

For example:This is what the program currently does:

Whereas I would now like it to do this:
match1("adipisci","sciip") returns true
match2("adipisci","sciipx") returns false because x does not exist in variable
match3["adipisci","adipisci"] returns true in array 1 and 2 if "sciip" is searched
match4["adipisci","adipiscix"] returns false in array 1 and true in array 2 if "sciipx" is searched

View 4 Replies View RelatedI wanted to try creating a basic expression first. I want someone to enter a string that is 2 - 20 characters long and only has letters. This is what I use so far, and it doesn't work, nothing happens at all when I run it.
Code:
// Check for a valid name.
var namePattern = new RegExp("/^[a-zA-Z]{2,20}$/");
if (namePattern.test(name))
{
window.alert("Invalid");
}
name comes from a input box I display on screen. Also, I would like to update the expression so that there can be one space in the string, but it cannot be at the beginning or end. So this string is like a persons name. Bob is OK, Bob Smith is also OK. Edit: Actually, it is doing something but its always coming back invalid.

Example for FirstName data input: Characters a-z,A-Z, hyphen, space are permitted. 0-1, !@#$%^&*()- etc are not permitted.
The plugin looks great but I am not able to figure-out how to limit which characters an end-user is allowed to input. Not just which characters are permitted but also which characters are not permitted.
I block some characters to be inserted in my input, for example I don't want the user to insert numbers in a firstname input
View 2 Replies View RelatedI am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'
