Escape special characters when building html code using javascript -

hi build html code dynamically using javascript. problem gives me syntax error when try specify css class table using . think need escape special characters = , "" here. , tried give error of illegal syntax well.

for (var i=0; i<array.length; i++) {     htmlstr = htmlstr+"<table class"+%3d+%22+"test"+%22+"><tr><th>a</th><td>"+array[i].a+"</td></tr><tr><th>b</th><td>"+array[i].b+"</td></tr><tr><th>c</th><td>"+array[i].c+"</td></tr></table>"; } 

does know correct syntax this?

thanks in advance!

htmlstr=htmlstr+'<table class="test"><tr><th>a</th><td>'                +array[i].a+'</td></tr><tr><th>b</th><td>'                +array[i].b+'</td></tr><tr><th>c</th><td>'                +array[i].c+'</td></tr></table>'; 

for example, if want encapsulate <input type="button" onclick="alert('hello, world!');"></input> in javascript string, can't in 1 run, because code contains both double " , single ' quotes. should this:

var htmlcode='<input type="button" onclick="alert('+"'hello, world!'"+');"></input>'; 

you may use both single or double quotes define string variable in javascript:

var str0='hello, world!'; var str1="hello, world!"; 

they absolutely equal.
