Href how to pass dynamic data

[![enter image description here][1]][1]In href how to pass path with dynamic data, below I'm giving my code:
var abc = response[i].DocumentName;
var photoName = "<a href='#Url.Content("~/UploadImage/")" + abc +'" target="_blank" >'+response[i].DocumentName+'</a>';
in debugger mode i am getting like this:-
photoName = "jpeg2_10514.jpg"
which is not working for me

Try this:
var photoName = "" + response[i].DocumentName + "";
In Javascript you have to escape doublequotes " with a backslash \ if you want them to appear in the string.
The backslash in + abc + "\" is there to escape the second " to enclose the href in doublequotes.
EDIT
I added the missing doublequote befor the anchor tag according to the tip of karan.

How to escape single or double quote in JavaScript?

I am trying to replace quote (') with \' so as to escape escape quote or double quote in string
<ul id="list">
</ul>
<button id="sethrefbtn" onclick="setlink();">Set Link</button>
function setlink(){
var data = {
playerID : 102458,
playername: "Real Madrid's cristiano Ronalado"
}
listring= "<li><a href='SearchServlet?q=" + data.playername.replace(/'/g, "\'"); + "&playerid=" + data.playerID + "&page=1#pg0'>"+ data.playername +"</a></li>";
$("#list").append(listring);
}
Here is fiddle: fiddle
The desired output should be:
Real Madrid's cristiano Ronalado

Your problem is being caused by it being in an HTML attribute (so you need to convert it to an HTML character reference and not escape it). You should deal with that by using DOM instead of string mashing to build your HTML.
However, in this particular case, you are putting it in a URL, so you should be escaping it for URLs first.
You can do that with encodeURIComponent, but since you are building an entire query string and are using jQuery, you can use param instead.
function setlink() {
var data = {
playerid: 102458,
q: "Real Madrid's cristiano Ronalado",
page: 1
}
var url = "SearchServlet?" + $.param(data);
var li = $("<li />").append(
$("<a />").text(data.q).attr('href', url)
);
$("#list").append(li);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="list">
</ul>
<button id="sethrefbtn" onclick="setlink();">Set Link</button>

listring= "<li><a href='SearchServlet?q=" + data.playername.replace(/'/g, "\'") + "&playerid=" + data.playerID + "&page=1#pg0'>"+ data.playername +"</a></li>";
Just replace the above statement in the code .
There is a semicolon in the middle of the statement in your code.

Passing an array to a function and escaping double quotes in Javascript

I am generating dynamic HTML and want to pass an array to the calling function. The array is also being dynamically generated.
The contents of pinfoarray are somewhat like this "Ice Hockey","Junior Basketball","Ladies Soccer"
var theHost = "<a href='#someDialog' onclick='chnghost(' + pinfoarray + ');' data-toggle='modal' class='button'>Change</a>";
How can make it send the array to the calling function without an error.

How about making it like this:
var anchor = document.createElement('a');
anchor.href = '#someDialog';
anchor.setAttribute('data-toggle','modal');
anchor.className='button';
anchor.onclick = function(){
chnghost(pinfoarray);
}

You need to properly terminate the string and encode the parameter. You also need to guard against reserved characters in your data (escapeHtml).
var theHost = "<a href='#someDialog' onclick='chnghost(" + escapeHtml(JSON.stringify(pinfoarray)) + ");' data-toggle='modal' class='button'>Change</a>";
If you're using jQuery, you can implement escapeHtml like so:
function escapeHtml(text) {
return $("<div/>").text(text).html();
}

You need to close the string double quote to put a javascript variable:
var theHost = "<a href='#someDialog' onclick='chnghost('" + pinfoarray + "');' data-toggle='modal' class='button'>Change</a>";

Javascript function parameter character escape

I need to pass a variable to a JavaScript function, but I have a little trouble. In the .cs file, I have written:
string id = "some'id";
this.Controls.Add(new LiteralControl("<input type=\"button\" onClick=\"myFunction('"+id+"')\">"));
As you can see there is an ' (single quote) in the id. Is there any way to work around this issue?

Escape ' with a \ (backslash). For example,
console.log('string with \'');

Escape your string for such kind of characters"/","\","'"
example
string id = "some/'id";

You should escape your string , which would lead to :
id = "some\'id";

<script type="text/javascript">
function myFunction(someid) {
someid = someid.replace('#', '\'');
alert(someid);
}
</script>
in Your code
string id = "some'id".Replace("'","#");
this.Controls.Add(new LiteralControl("<input type=\"button\" value=\"Test\" onclick=\"myFunction('" + id + "');\">"));
Hope this will Helps you..

JavaScript, the use replace

var text_source="<a href='c:/exam_file.xls' target='_blank'>file downdload</a>";
text_search="file";
text_source.replace(new RegExp(text_search, 'gi'),
"<span style='font-weight:bold'>" +
text.toLowerCase() + "</span>");
The "a tag" link address has also changed:
<span style='font-weight:bold'>file</span> download
But, It should look like this. I have to change the text value in the "a tag".
<span style='font-weight:bold'>file</span> download

I will address what I said in a second, but you can do this without a loop with just pure regex. Below is how I accomplished this:
var text_source = "<a href='c:/bilmem_ne_dosyasi.xls' target='_blank'>Dosya Downdload</a>";
text_search = "dosya";
var patt = new RegExp("(<a .*?>)(" + text_search + ")(.*?</a>)","gi");
var text_source = text_source.replace(patt, function(match, $1, $2, $3) {
return $1 + "<span style='font-weight:bold'>" + $2.toLowerCase() + "</span>" + $3;
});
document.write(text_source);

Getting back to what I said earlier, however, html can be a very, very complex language, and although regex can be used to parse it, partially, it should not be used for large quantities of data. Some patterns are too intricate to match against.

To ensure that your RegExp runs only against the content of the elements, you will need to select all of the elements that you want to manipulate and check their contents.
As an example:
var regExp = /dosya/ig;
[].slice.call(document.getElementsByTagName('a'), 0).forEach(function(element) {
if(regExp.test(element.textContent)) {
element.innerHTML = element.textContent.replace(regExp, function(text) {
return '<span style="font-weight: bold">' + text.toLowerCase() + '</span>';
})
}
});
There is also a jQuery pseudo selector :contains that does a similar thing.

Whilst the replies about not using regexes with HTML or XML are on the whole, correct, you could use the following for simple cases where you don't have too many nested tags:
var text_source="<a href='c:/bilmem_ne_dosyasi.xls' target='_blank'>Dosya Downdload</a>";
text_search="(<[^>]*>[^<]*)(dosya)([^<]*<[^>]*>)";
var replaced = text_source.replace(new RegExp(text_search, 'gi'), "$1<span style='font-weight:bold'>$2</span>$3");
