Search And Replace In Large String?
Jun 1, 2009
I have a large string, but need to search for a specific character and replace it only if it is between two other items. Examplemystring would be something like this<parent><child1>1 & 2</child1><child2>1 & 2</child2><child3>1 & 2</child3></parent>I need to replace the & symbol in child2, but not 1 or 3. I am trying to figure out how to replace just any & signs in child2, but I need to leave them alone in child 1 and 3.I know I can do a replace(), but just not sure how to limit it to only the one I need

trying to write a function where i can pass an array and string and replace the value in return. i.e
var inputStr = "010203040506070809111213141516171819";
i want to pass this value in function and replace each number (number ranges are 01-09 and 11-19 only) i.e if i pass 01 want to replace that with A,02 with B etc.. so problem is i would pass input string and pass back as string after replacing those values by running through the below function. wrote the following,cant seem to split my inputStr into 01 02 etc tried splice and split no luck :

Here is my code:
<script type="text/javascript">
var str="Welcome to Microsoft! Microsoft Microsoft";
var stringToBeFound = 'Microsoft'
var ReplaceString = 'site'
document.write(str.replace(stringToBeFound , ReplaceString ));
</script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database

I've been told that jQuery can do this.
Simple form which includes a drop down list of users obtained from a database which is displayed using a form select entry with options for each entry. problem is, the list can be quite long, upwards of several hundred.
In PHP, I added a filter box (text box) which the visitor can enter in a substring that is then used to obtain and display only matching entries. Works great, but it needs to reload the page to do its thing.
I've been told that jQuery can be used to do the same thing without having to reload the whole page.
The filter box would be used to call an existing PHP script which obtains the names based on the filtered string. I can change this script to output the data in any format necessary including raw format to full option formatted strings.
how to set this up so that it gets called and replaces the current option content.

I have this large string mixed in with PHP because the drop downs offer a query from the users already uploaded. Anyways, somewhere there is an error inside the string, probably because the single quotes cancel each other - but I can't seem to combine them to fix it. Let me know if you see anything, or have tips.
var inner = '<colgroup><col span="1" width="250" /><col span="1" width="200" /></colgroup><tr><td class="leftAlign">Letter of Recommendation</td><td><? if(mysql_num_rows($f) != 0) {echo '<select name="recommendation_archive">';include "includes/objects/files_drpDwn.php";echo '</select>';}else { echo 'No files in archives.'; }?></td><td><input name="recommendation_upload" type="file"

I ran into a problem that I could not fix myself, I am trying to replace a string with another string, the replace lines look like this:
Code:
var word = document.getElementById("word").innerHTML; document.getElementById("word").innerHTML = wordd.replace(/B/g, '<span class="style106">B</span><span class="style107"> </span>'); It works just perfectly if left alone, but I need to replace every letter inside this string, adding those style and span tags around each and every letter. So if I add another line to this code, like this:

I converted the whole thing to php, and it looks better when looking at the source code, but it still doesn't work. Does anyone see anything wrong with the code here: Here's the php that produces the string:
Code:
<?php
echo 'var inner = '<colgroup><col span="1" width="250" /><col span="1" width="
200" /></colgroup><tr><td class="leftAlign">Letter of Recommendation</td><td>';
if(mysql_num_rows($f) != 0) {
echo '<select name="recommendation_archive">';
include "includes/objects/files_drpDwn.php";

My page populates a table with a list of names and other information from a
JavaScript object. I receive changes (adds, change & delete) to that list,
convert it into a JavaScript object. I do understand how to add the new
names to the list.
I have 3 questions:
1) How can I search through the table rows to find the rows to be changed
or removed?
2) How can I resort the table, so the names continue to appear in
alphabetical order.
3) How can change or remove data in the cells, once I've found the
appropriate row?

i have a implementation where i need to perform a search and replace. i will try to explain to the best of my ability. i have a variable, var a = "THIS IS SOME SOME TEXT";
then i have another array variable, var b = new Array(); which contains elements in key=value format eg. SOME=NEWSOME so what i need to do is, i need to loop through this array and if SOME exists in var a, then i need to replace it with NEWSOME. so for each value before =, if it exists in var a replace it with whats after =. and replace only once, so if SOME exists multiple times just replace the first occurence.
so essentially my final string would be, THIS IS NEWSOME SOME TEXT.

I need to search and replace patterns in web pages, but I
can't find a way even after reading the ad hoc chapter in New Rider's
"Inside JavaScript".
Here's what I want to do:
function filter() {
var items = new Array("John", "Jane");
for (x = 0; x < items.length; x++) {
//Doesn't work
pattern = '/' + items[x] + '/'
//Doesn't work either
document.body = document.body.replace(pattern,"IGNORED");
}
ie., create an array of items to look for in the BODY section of the
page, and if any item exists, replace the item with IGNORED.
Anyone knows how to do this?

In a string (that contain the Flash version installed), I want to replace:
all "," by "."
"win" by <nothing>
all spaces by <nothing>
So far I do it this way:
strFlashVer = strFlashVer.replace(/,/g, '.');
strFlashVer = strFlashVer.replace('win', '');
strFlashVer = strFlashVer.replace(/ /g, '');
but I'm sure theres better way (I'm not really good with reg exp).

I'm trying to reduce a large number of pdf files to text format. Acrobat has a batch processing feature that will convert the files, and also allows a JavaScript to be executed as part of the conversion process.
I would like to add JavaScript code that allows me to replace and/or remove certain text/characters from the file.
Examples would be:
A) Remove all double, triple, multi-spaces and carriage returns
B) Change all uppercase characters to lowercase
C) Remove all punctuation
What i'm really aiming for is to be able to run the batch process in Adobe, then have a javascript filter out all that junk within a file with X amount of lines, not just one.

is it possible to combine the the following functions with each other in an array for example and if so, would someone be kind enough to show me how. the reasons are 1. to see if it is at all possible and 2. to learn so that I can combine further possibilities in the future. the first script compares user keywords from search mashines and the second replaces certain strings/paterns with others.

I have a validation regular expression: [?&-#$%():;,._ 0-9a-zA-Z] in a hundreds of pages in edit boxes. Is there anyway I can on-the-fly add two items to this list: (after a page loads)
1) A single quote : '
2) A double quote : "
Sort of like a search and replace for the ENTIRE form (html document).

I am using javascript to search for the '*' character in a string (ie. 'username*:') but using search('*') does not work. How do I search for it since the search function takes a regexp argument and * messes that up?

this function is supposed to search a string for decimals and tell me how many of them it has found, but for some reason, it's not doing it right. since the "period" character is a special character in regular expressions,I went ahead and escaped it, but it's still doesn't work.
function ImprovedFormatAmount(ElementId)
{
var oElement = document.getElementById(ElementId);
var ElementValue = oElement.value;
var DecimalRegXp = /./g;
var OutputValue = ElementValue;
if (OutputValue.length > 0)
{alert (OutputValue.search(DecimalRegXp));}
}
