javascript - How to get content of a child div? -

why doesn't work:

<div class="store" id="vframestore">     <div>http://www.youtube.com/embed/_6dpbcouklu?showinfo=0&modestbranding=1&fs=0&rel=0</div>     <div>http://www.youtube.com/embed/zmr0q4jz_um?showinfo=0&modestbranding=1&fs=0&rel=0</div> </div> 

js

var = $("#vframestore").children[0].html; console.log(a); 

error: uncaught typeerror: cannot read property 'html' of undefined

you can following.

var = $("#vframestore").children().first().html(); 

or

var = $("#vframestore div").eq(0).html();
