JQuery single and double quotes problems

Question

I am trying to insert a tag into the page. but inside that a tag, it has both single quote and double quote, so i try put that part into an variable Var content. Can someone tell me why this var content is not showing on onclick after code runs?

var content = "javascript:window.open('https://ds.contactatonce.com/ds/p10819departmentselector.htm?OriginationUrl='+encodeURIComponent(location.href),'','resizable=yes,toolbar=no,menubar=no,location=no,scrollbars=no,status=no,height=520,width=450');return false;" $('<a style ="float: left; margin-top: 20px" href="#" onclick=" + content + " ><img onerror="this.height=0;this.width=0;" border="0" alt="Click to instant message Representative Now!" title="" src="https://dm5.contactatonce.com/getagentstatusimage.aspx?MerchantId=270075&ProviderId=10819&PlacementId=10"></a>').insertBefore('.header-contact-phone');

it was like this before but it keep showing errors

$('<a style ="float: left; margin-top: 20px" href="#" onclick="javascript:window.open('https://ds.contactatonce.com/ds/p10819departmentselector.htm?OriginationUrl='+encodeURIComponent(location.href),'','resizable=yes,toolbar=no,menubar=no,location=no,scrollbars=no,status=no,height=520,width=450');return false;" ><img onerror="this.height=0;this.width=0;" border="0" alt="Click to instant message !" title="Click to instant message a Now!" src="https://dm5.contactatonce.com/getagentstatusimage.aspx?MerchantId=270075&ProviderId=10819&PlacementId=10"></a>').insertBefore('.header-contact-phone');

var content = "javascript:window.open('ds.contactatonce.com/ds/… false;" $('').insertBefore('.header-contact-phone'); — Li Wen

Please move all code into the question itself, rather than adding it as a comment. — evolutionxbox

I did that before, but is causing a error because inside the double quotes it has single quote, — Li Wen

Use the escape character \ before the quotes like this:

var y = "We are the so-called \"Vikings\" from the north.";

see this links:

Among all the beautiful documentation online it's so sad to see such low quality links here.
