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));}
}

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

function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];

return getVars;
}A simple page to test this looks like<html>

<title>Test</title>
<script>
function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));

<script>
var g = parseGetVars();
for (var i in g)

I'm writing a piece of JS code that returns a result of true if the pattern appears in string as a substring (case sensitive) but would like to extend its functionality to returns true if all the individual characters of pattern appear in string (regardless of order).

For example:This is what the program currently does:
match1("adipisci","pis") returns true
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

I need to insert a string into a textarea, where the cursor is when a button is clicked. I tried google for this one, but all I found was how to change the text in the textarea, and how to append something to the end, but not how to insert where the cursor is. Does anyone know how to, or have a script that does this?

View 10 Replies View RelatedUsing js, I would like to write a single string of several phrases into a textarea such that each phrase is aligned in order, one above the other. I tried a function that receives the string argument and splits it into an array. With a 'for-loop', elements of the array are assigned in turn to the textarea value. This gives me only the last element ('GROUP BY room') displayed , since it was the last assigned. My placing of a '+', a break("<br>") or a newline( ) didn't help. To get the idea, the following piece of script displays the string as broken, stacked, but not in the textarea where I want it:
$Statement = "SELECT all data,
FROM Departments,
WHERE grouphead = 'Milo',
GROUP BY rooms";

I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {
if (Selection=="Select State")
alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
