Server side fix for widows in text string

I'm having an issue with server side widows fix.
I'm able to fix widows/orphans with client side javascript.
However I would prefer to do it server side before the page renders. Unfortunately my C# is limited. How would I be able to accomplish this? Or at least get an idea of how to accomplish this.
Here's the javascript that I've used.
var wordArray = $('element').text().split(' ');
if (wordArray.length > 1) {
wordArray[wordArray.length - 2] += ' ' + wordArray[wordArray.length
- 1];
wordArray.pop();
$(''element'').html(wordArray.join(' '));
}
Thank you in advance.

Please read my comments inside the code
public string Model_fix(string ElementText)
{
var result = string.Empty;
// the compiler will set wordArray as List of string and not an array
// list in c# is more similar to an array in javascript
var wordArray = ElementText.ToString().Split(' ').ToList();
if (wordArray.Count > 1)
{
wordArray[wordArray.Count - 2] += "' '" + wordArray[wordArray.Count - 1];
wordArray.RemoveAt(wordArray.Count - 1); // equivilent to Array.pop in javascript
result = string.Join(" ", wordArray); // equivilent to Array.join() in javascript
}
return result;
}

Manipulate text from form - JavaScript/Jquery

Hello I am working on a project and last night I had a thought that would make a lot of what I am wanting to do a heck of a lot easier, the only problem is I am not sure on the best way to tackle it. Let me explain....
I have a form on a website where a user enters a VIP ID that is in a pre-determined format and follows a logical naming convention.
Example: app.prod.platform.org.dc1.prod.site.com-HTTP_80tcp-00000000-lb
I want to pull out the following information from the entered text.
prod.platform.org.
Then I want to reverse it logically
.org.platform.prod
And then I want to replace the “.” For “/”
/org/platform/prod
And finally I want to add a postfix of “/open*”
/org/platform/prod/open*
So in short,
INPUT = app.prod.platform.org.dc1.prod.site.com-HTTP_80tcp-00000000-lb
OUTPUT = /org/platform/prod/open*
I am using javascript/jquery for everything else but I am pretty new to all of this so I tend not to know the best route to tackle a problem. If I need to provide some more detail I can do. Any help is much appreciated.

Or simple like this
var input = "app.prod.platform.org.dc1.prod.site.com-HTTP_80tcp-00000000-lb" ;
var output =
"/" +
input
.split(".")
.slice(1, 4)
.reverse()
.join("/") +
"/open";

var output =
"/" +
"app.prod.platform.org.dc1.prod.site.com-HTTP_80tcp-00000000-lb"
.split(".")
.slice(1, 4)
.reverse()
.join("/") +
"/open";

You can try below code :
var input = "app.prod.platform.org.dc1.prod.site.com-HTTP_80tcp-00000000-lb";
var tempArr = input.split(".");
var newArr = new Array();
for(var i=1;i<tempArr.length;i++){
if(tempArr[i]=="org" || tempArr[i]=="net"){
newArr.push(tempArr[i]);
break;
}
newArr.push(tempArr[i]);
}
newArr.reverse();
var output="/"+newArr.join("/")+"/open*";

unexpected string in append() jquery

I'm trying to append a some HTML to a code in jquery, but chrome keeps throwing "unexpected string" at the append function, here's the code :
for (var i =0 ;i<resultArray.length;i++){
$.ajax({url:"getExpenseInfo.php",type:"POST",data : {
'expenseId' : resultArray[i]["expenseId"]
},success:function(expense){
expense = $.parseJSON(expense);
$("#mainDiv").append("<div class=\"row\">".expense["expenseName"]."</div>");
}});
}

I guess you're mixing up php and js syntax, string concatenation works with + in js and not ..
$("#mainDiv").append("<div class=\"row\">" + expense["expenseName"] + "</div>");

Your string concatenation in your append function is a little off. Try something like this:
for (var i =0 ;i<resultArray.length;i++){
$.ajax({url:"getExpenseInfo.php",type:"POST",data : {
'expenseId' : resultArray[i]["expenseId"]
},success:function(expense){
expense = $.parseJSON(expense);
$("#mainDiv").append("<div class=\"row\">"+expense[expenseName]+"</div>");
}});
}

JQuery / Javascript & Split within split?

A Caveat: As a dilettante I lack the vocabulary to precisely describe my problem. Bear with me.
Let's assume I have a string like the following one:
A1%%A2%%A3%%A4||B1%%B2%%B3%%B4||C1%%C2%%C3%%C4||D1%%D2%%D3%%D4
Using JavaScript / JQuery I would like to split it twice (using '||' and '%%' as delimiters) and have the following HTML as output:
<p><input value="A1"></input><input value="A2"></input><input value="A3"></input><input value="A4"></input></p>
<p><input value="B1"></input><input value="B2"></input><input value="B3"></input><input value="B4"></input></p>
<p><input value="C1"></input><input value="C2"></input><input value="C3"></input><input value="C4"></input></p>
<p><input value="D1"></input><input value="D2"></input><input value="D3"></input><input value="D4"></input></p>
I know how to do basic splitting and joining, but this goes beyond my comprehension.

You can use something like this.
s = "A1%%A2%%A3%%A4||B1%%B2%%B3%%B4||C1%%C2%%C3%%C4||D1%%D2%%D3%%D4";
s2 = s.split("||");
s2.forEach(function(item){
s3 = item.split("%%");
s3.forEach(function(item2){
console.log(item2);
});
});

You can use replace
function splitString(match, part) {
switch (part) {
case '%%':
return '"></input><input value="';
case '||':
return '"></input></p>\n<p><input value="';
}
}
var formattedValue = 'A1%%A2%%A3%%A4||B1%%B2%%B3%%B4||C1%%C2%%C3%%C4||D1%%D2%%D3%%D4'.replace(/(%%|\|\|)/g, splitString);
formattedValue = '<p><input value="' + formattedValue + '"></input></p>';
console.log(formattedValue);

All split joins. It will be fast.
var str = 'A1%%A2%%A3%%A4||B1%%B2%%B3%%B4||C1%%C2%%C3%%C4||D1%%D2%%D3%%D4',
result = str.split('||').join('"></input></p>\n<p><input value="');
result = '<p><input value="'+
result.split('%%').join('"></input><input value="')+
'"></input></p>';
console.log(result);
//or
//alert(result);
//
With problems like this don't think so much about what format you want.
Start with something simple first like:
var result = str.split('||').join('><');
result = str.split('%%').join('><');
Then you might see how to use the longer string to get what you actually want.

How can I write data in a single line on text file using javascript

I am trying to write data in a .txt file using JavaScript function.
My function :-
function WriteToFile()
{
var fso = new ActiveXObject("Scripting.FileSystemObject");
var s = fso.CreateTextFile("test.txt", true);
for(var j=1;j<9;j++)
{
if(document.getElementById('chk'+j).checked)
{
s.WriteLine(' ');
s.WriteLine(document.getElementById('item'+j).innerText);
s.WriteLine(',');
s.WriteLine(document.getElementById('txtBx'+j).value);
s.WriteLine(',');
s.WriteLine(document.getElementById('txtBxx'+j).value);
s.WriteLine(';');
}
}
alert("written");
s.Close();
}
Now the problem is that data being written on a new line.
(maybe because i am using s.WriteLine ?)
I want all the data to be written in a single line. how can i achieve this?
to elaborate more, my current output looks like this
abc
,
1
,
cdf
;
def
,
3
,
ehi
;
I want it like this-
abc,1,cdf;def,3,ehi;

Use s.write() instead of s.writeLine(). As the name implies, the second function is for writing whole lines, and it adds a newline after it.

Just add everything to a variable then write the line.
var st = document.getElementById('item'+j).innerText;
st += ','
st += document.getElementById('txtBx'+j).value;
s.WriteLine(st);
