Trying to escape quotes in a href tag

I have the following line of code,
$("#busdata").append("<div>" + data.response.results[i].webUrl + "</div>");
I essentially want the "data.response.results[i].webUrl" to replace the url string, but I'm not quite sure how to escape the quotes properly.

You can escape quotes by replacing them with \"
or just use single quotes - '
So "<div><a href="url">" becomes
"<div><a href=\"url\">" or "<div><a href='url'>"

a single quote ' and a string concatenator +
$("#busdata").append("<div><a href='"+ data.response.results[i].webUrl +"'>" + data.response.results[i].webUrl + "</a></div>");

Your syntax is wrong. You need to escape quotes. Change your <a href="url"> to <a href=\"url\"> like this:
$("#busdata").append("<div>" + data.response.results[i].webUrl + "</div>");
Or if you feel that's a bit tough, you can exchange the quotes, ' for ":
$("#busdata").append('<div>' + data.response.results[i].webUrl + "</div>");
Else, if you are trying to add the URL from the response:
$("#busdata").append("<div>" + data.response.results[i].webUrl + "</div>");

if url is a variable
$("#busdata").append("<div><a href='" + url +"'>" + data.response.results[i].webUrl + "</a></div>");
and if you want to write by yourself
$("#busdata").append("<div><a href='url'>" + data.response.results[i].webUrl + "</a></div>");

You can store it in variable instead :
var url = data.response.results[i].webUrl;
$("#busdata").append("<div>" + url + "</div>");
Hope this helps.

Simply do it following my example:
var a = $('<a />', {
href: 'url here',
text: 'text here'
}); $('body').append(a);

You could do this :
$("#busdata").append("<div><a href='"+data.response.results[i].webUrl +"'>" + data.response.results[i].webUrl + "</a></div>");
Since you are using double quotes for the string to append, you can use single quotes around the variable in the href attribute and then add that variable.

This is most easily achieved by not building HTML by smashing strings together in the first place.
$("#busdata").append(
$("<div />").append(
$("<a />").attr("href", data.response.results[i].webUrl)
)
);

Escaping quotes is not necessary
$("#busdata")
.append("<div><a href="
+ data.response.results[i].webUrl
+ ">"
+ data.response.results[i].webUrl
+ "</a></div>"
);

How to form variable string with HTML and corresponding quotations

I'm building a string of text using HTML and variables from a JSON file. The issue is that the quotation marks from the HTML are conflicting with the quotations from the js expression - specifically when I'm trying to build a URL from a string of a URL partial + a json variable.
Here's my code. Any help?
output += '<li><span><a>' +
jobs[i].title +
'</a></span><span>' +
jobs[i].city +
'</span><span><a href='http://user.theresumator.com/apply/'' +
jobs[i].board_code +
'><button>More Info ›</button></a></span></li>';
}
My desired outcome is something like:
<li><span><a>Social Impact Strategist (Los Angeles or New York)</a></span><span></span><span><button>More Info ›</button></span></li>

Escape your quotes with \:
output += '<li><span><a>' +
jobs[i].title +
'</a></span><span>' +
jobs[i].city +
'</span><span><a href=\'http://user.theresumator.com/apply/' +
jobs[i].board_code +
'\'><button>More Info ›</button></a></span></li>';
}
or use double quotes ":
output += '<li><span><a>' +
jobs[i].title +
'</a></span><span>' +
jobs[i].city +
'</span><span><a href="http://user.theresumator.com/apply/' +
jobs[i].board_code +
'"><button>More Info ›</button></a></span></li>';
}
The 2nd one will match your desired outcome with double quotes perfectly.

Here's the working code! I broke it out on a separate line and add double quotes by themselves contained in single quote.
output += '<li><span><a>' +
jobs[i].title +
'</a></span><span>' +
jobs[i].city +
'</span><span><a href=' +
'"http://user.theresumator.com/apply/' +
jobs[i].board_code +
'"' +
'><button>More Info ›</button></a></span></li>';
}

Passed URL string not interpret as a string

I read quite some articles and tried some approaches, but couldn't get it to work.
htmlCode += '<button id="' + addButtonId + '" title="' + addButtonTitle + '" class="button" onclick="getProductUrl(' + url + '); return false;"><span><span>' + addWithButonTitle + '</span></span></button>';
and the function itself:
getProductUrl: function(url) {
return setLocation('\'' + decodeURIComponent(url) + document.getElementById('qty_field').value + '\'');
},
Apparently, the string value of the url is not treated as a string. I get an error of missing bracket here: getProductUrl(http:^//...rest of the url. Of course the problem is not in the bracket, but in the fact that the // are treated as a start of a comment.
So the thing that I have to do is to pass this url string value CORRECTLY as a string.
I tried first decoding and then passing (because decodeURIComponent(url) should return string. Also I tried String(url) and url + "". Also somehow escaping the special characters: url.replace('/','\/') or even the /g thingy, which didn't work at all.
So, all these approaches were unsuccessful. I would really appreciate a hint or a solution here.

Try this one
onclick="getProductUrl('" + url + "');"
For your updated line of code:
htmlCode += '<button id="' + addButtonId + '" title="' + addButtonTitle + '" class="button" onclick="getProductUrl(\'' + url + '\'); return false;"><span><span>' + addWithButonTitle + '</span></span></button>';

Passing & symbol in jquery

I am trying to insert an email link using jquery, but if the email body has a & in it, it will not work.
$('#em_button').html('<img src="' + homeUrl + '/' + tUrl + '/img/email.png" title="Email this photo" />');
The part that is breaking it is &img=. I've tried using & but that didnt work either. Any suggestions?
Note: If there is no &, everything works fine.

You can try this, hope it works
'%26img='

Without knowing what is in js_images[getImg], it's hard to say what is going wrong.
One thing to keep in mind is that you should always encode components before creating a URL. For example:
var x = encodeURIComponent(js_images[getImg].title)
$('#em_button').html('<a href="mailto:?subject=A Photo: '+ x +'&body...')
Furthermore, if you're creating something like a link, you might want to make things clearer by writing it as follows:
var url = 'mailto:subject=A Photo: ' + encodeURIComponent(js_images[getImg].title) +
'&body=I thought you would like this photo: ' + encodeURIComponent(thisPage) +
'&id=' + encodeURIComponent(getGall) +
'&img=' + encodeURIComponent(js_images[getImg].filename);
var src = encodeURIComponent(homeUrl) + '/' +
encodeURIComponent(tUrl) + '/img/email.png'
var $a = $('<a/>', {
href: url
});
var $img = $('<img/>', {
src: src,
title: 'Email this photo'
});
$a.append($img);
$('#em_button').html($a);
$('#em_button').html('<img src="' + homeUrl + '/' + tUrl + '/img/email.png" title="Email this photo" />');

If you just append the URL parameters and the body text into one string, the & from inside the body text would be parsed as URL argument. In PHP i would use urlencode to encode occurrences of such characters into %xx-values.
Looking at the answer of Константин Рекунов, I would assume you could use encodeURIComponent to encode the body contents.
encodeURIComponent( thisPage + '?id=' + getGall + '&img=' + js_images[getImg].filename )
See: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/encodeURIComponent
You could avoid that problem by using URL rewriting on your server for the image files.
Instead of:
thisPage + '?id=' + getGall + '&img=' + js_images[getImg].filename
…it might be:
thisPage + '/' + getGall + '/img/' + js_images[getImg].filename

I think your problem is you have a second ? in your query string.
You should substitute the second ? with &. Also all your & should be written as &
$('#em_button').html('<img src="' + homeUrl + '/' + tUrl + '/img/email.png" title="Email this photo" />');

Instead of using "&" try using &

use +encodeURIComponent('&')+

How to Solve this "missing ) argument after list"?

This looks like a trivial question, but I am not sure how to deal with it. I have a DIV tag generated from javascript that goes like this:
$('#results')
.append('<DIV id='
+ A.pid
+ ' onmouseover=function(){google.maps.event.trigger(marker, 'mouseover');};><H3>'
+ A.name
+ '</H3></DIV>');
Firebug is giving me an error "missing ) argument after list" as it does not recognise the ) immediately after 'mouseover'. How do I resolve this?
UPDATE:
I understand this is about escaping quote, just that doing \'mouseover\' produces a syntax error upon mouseover of the DIV and doing "mouseover" produces a blank document.
The syntax error reads: function(){google.maps.event.trigger(marker,

You need to escape quote if it's inside another quote:
var x = "I don't like you!";
var y = 'I don\'t like you!';
var z = 'echo "this text?";';
To implement it on your case, it would be like this:
'<DIV id='
+ A.pid
+ ' onmouseover=function(){google.maps.event.trigger(marker, \'mouseover\');};><H3>'
+ A.name
+ '</H3></DIV>'

You issue is in the use of the ' character to delimit both the function and the arguments in your call.
Either switch one set of ' out for " or use \' around the values of the argument
$('#results')
.append('<DIV id='
+ A.pid
+ ' onmouseover=function(){google.maps.event.trigger(marker, "mouseover");};><H3>'
+ A.name
+ '</H3></DIV>');
//OR
$('#results')
.append('<DIV id='
+ A.pid
+ ' onmouseover=function(){google.maps.event.trigger(marker, \'mouseover\');};><H3>'
+ A.name
+ '</H3></DIV>');

Try to generate the following string
'<DIV id=' +
A.pid +
' onmouseover=\"google.maps.event.trigger(marker, \'mouseover\');\"> <H3>' +
A.name + '</H3></DIV>'

You need to put " around the values of your html attributes. Otherwise the browser thinks the attribute ends at the next whitespace and that is exactly right after the (marker, part.
$('#results')
.append('<DIV id="'
+ A.pid + '"'
+ ' onmouseover="function(){google.maps.event.trigger(marker, \'mouseover\');};"><H3>'
+ A.name
+ '</H3></DIV>');

Several things
Stop putting HTML in all caps. This is the 21st century not the 20th century.
You don't need an anonymous function for the onmouseover event.
Wrap attribute values in either single or double quotes (I use double below).
Read about JavaScript strings and quotes. Here is a tutorial.
Try this
$('#results').append('<div id="' +
A.pid +
'" onmouseover="google.maps.event.trigger(marker, \'mouseover\');"><h3>' +
A.name +
'</h3></div>');
