JavaScript - Can't assign variable -


my simple code :

var child1 = document.getelementsbyclassname("item1")[0].innerhtml; var child2 = document.getelementsbyclassname("item2")[0].innerhtml; var child3 = document.getelementsbyclassname("item3")[0].innerhtml; var child4 = document.getelementsbyclassname("item4")[0].innerhtml; var arr = [child1, child2, child3, child4];

but when run document in firefox, open console , type child1, or type arr, undefined in console.

when type, say, document.getelementsbyclassname("item1")[0].innerhtml;, right content in console, :

"<div class="inh">♠</div>"

this content, can't assign variable !! great.
