javascript - JQuery单双引号问题

Question

我正在尝试将标签插入页面。但在该标签内部，它既有单引号又有双引号，所以我尝试将该部分放入变量 Var 内容中。有人可以告诉我为什么代码运行后 onclick 上没有显示这个 var 内容吗？

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');

以前也是这样，但一直显示错误

$('<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');

在引号前使用转义字符\ 像这样:

var y = "我们是来自北方的所谓“维京人”。";
