I've written this javascript that puts lines of text into a readonly textarea, each line ends with a newline character. I have a function that checks that no duplicates exist, it does this by splitting the textarea by newlines into an array. This works as it should in Firefox, but not in IE. Code:
View 2 RepliesI dynamically make a textarea and save the text, but when I try to output it with javascript, the newlines screw it up... if you don't understand what i mean, here is some code:
Code:
With that newline in javascript, the javascript throws an error. i am working in jsp, so how would i change the text that is put into the textarea with javascript without changing the newlines?
Here is how i try changing it:
Code:
But it doesnt change anything,
PHP has a function called nl2br() which takes all the newlines in a
string and turns them into break tags <br>. I need to do the same in
javascript. Is this about right? I'm not sure how one is supposed to
reference invisible characters in Javascript strings. I took an example
on the web and tried to modify it to my uses.
function nl2br_js(myString) {
var regX = /
/gi ;
s = new String(myString);
s = s.replace(regX, "<br />
");
return s;
}
After looking around quite a bit using Google, I still couldn't find
out what the gi in the above example is for. What is it?
I have some Javascript code that reads and sometimes sets the content of
a textarea. I want this to be reasonably browser and platform independent. My question is, what characters should I expect to find at the end of a line? I suspect that I need to cope with either "" or""; can someone confirm?
Setting the content is more of a challenge. I don't want to have nasty browser detection to select what to use for newlines. Is there one newline pattern that is safe for all browsers?
I need to take the text in a textarea, split it into an array, and have the items in the array be added to a dropdown menu. When I try to split the value of the textarea (which, by the way, contains comma-delimited text) into an array, the array invariably ends up with only one item in it, and that item contains the entire contents of the textarea all jammed together with the commas removed.
The offending code:
Code:
In my test page, the text area (DownListTextBox) contains "yes,no" and when the alert fires it shows that the array has a length of 1. The Option added to the dropdown list has a text of "yesno". So, what did I do wrong?
For some reason when I click the submit button, nothing gets displayed in the textarea.
Code:

I have a pre-populated array in a JavaScript. How to populate TEXTAREA field with the text from that array, each entry on different line on page load? Say, value at index 1 will come at line 1; value at index 2 will come at line 2 and so on.

I have a section of javascript that declares a global variable for a few functions, like this incomplete code
Code:
The above, in its full version, changes the text in a textarea. In my php code, if I include the above code above the textarea, it all works as expected.
The problem is that I may have more than one textarea - the number cannot be known beforehand. If I include the above before each textarea, the pointer gets confused as to which string belongs to which textarea since the global variables get redefined many times. In php, this would be a simple problem to solve with a mutildimensional array but, from what I understand, javascript doesn't have such arrays.
Someone can provide a solution that will allow me to use the same block of code over and over in the same file.

displaying content from array into textarea
View 4 Replies View RelatedI am looking to have the user input a word into a textbox then when the user hits an "Add" button, the word is stored to an array and then is displayed in a table. I also want the textbox to clear after the "Add" button is pressed. Next, I want the user to be able to input another word into the textbox and when the "Add" button is pressed, have that word stored to same array as the first word but just to a different number.ingredient(0)=first word; ingredient(1)=second word. Then I want the second word to be displayed right below the first word in the table, in the next line down.This is what I have so far.[URL]...

<h2><u>Add Element to Array</u></h2>
[code]...
I'm trying to add the text of a textarea form to the string that's contained at:
myarray[a][b][c]
It was easy to pull out the value of the textarea with this:
textinput = $('#mytextarea').val();
But then when I try to add the variable into the array, it doesn't work. I'm not able (apparently) to do this. Fingers crossed that I'm doing something dumb?
This doesn't work:
myarray[a][b][c] += newstringvariable;
Nor this:
myarray[a][b][c] = myarray[a][b][c] + textinput;
I'm guessing there is a very simple (probably syntax related!) solution to this. I'm open to doing this via jQuery or regular javascript.
How would i change back to the default length of textarea?
I have this comment area that after clicking submit i will append the new comment in the list of comments through ajax... i got one problem though, everything is working perfectly well except for the textarea that won't change back to it's default size...
EXAMPLE:
The problem is that the textareawon't change back to it's default size // let's say that the default size is rows=3
I've been trying to fix this.

I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target
What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..
View 7 Replies View RelatedI am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.
View 9 Replies View Relatedis this correct
var mid = math.floor((0 + array.length)/2)
from here you could use array.slice to divide the array into two equal sized arrays?
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I am building a customised javascript prototype to sort an associative array on the array key (in ascending order). Basically, I am separating the array keys into a separate array and then using .sort() to sort the keys and then reassembling the original associative array elements according to the sorted keys array.
The sorting works ok except that when I run the test code below, the outputed sorted associative array has an extra element at the end of the array whose key is the name of the prototype function and the value for that element is the function code itself. Obviously I am misunderstanding something about associative arrays or how javascript prototypes work.

I want to have a simple code such that some data is stored in array. When we create a search box it has to give suggestions from the data stored in array.
