executing javascript functions within a string

Question

Is there a better way to inject a dynamic text into the html string other than the code specified below?

var code = 'siteCode1';

html code as a string:

existing: '<p>Log in with your'+ eval("siteVarObj('+code+').siteName") +'account</p>',
function siteVarObj(siteCode){
 if(siteCode === 'siteCode1'){
 this.siteName = 'google.com';
 this.siteContactUsURL = '';
 }else if(siteCode === 'siteCode2'){
 this.siteName = 'stackoverflow.com';
 this.siteContactUsURL = '';
 }
 return this;
 }

Answer 1

This should work just fine:

var code = 'siteCode1';
var myHTMLString = '<p>Log in with your '+ siteVarObj(code).siteName + ' account</p>';

Answer 2

I would generally suggest to avoid execution of any input from within eval because eval opens up your code for injection attacks when used inproperly.
