<input type="number" id="first" value=" "><button onclick=" myfunc()>closing tag> , how to take value of input length,

Question

I want value of input element but directly as an argument of myfunc(length),

for example, sometime we use myfunc(this.value),
but now , since value belong to other tag,
so how to take value of other tag in my example,

Answer 1

You can do:

myfunc(this.parent.firstChild.value);

... or something like that, depending on the html context ^^

Anyway, this could becomes a little tricky, as some browsers considerate empty node text in child elements list, and other not :P So, safer to do something like:

myfunc(this.parent.getElementsByTagName('input')[0].value);

Or you can use window.queryQuerySelctor() to select your input with an absolute css path selector string, avoidind the use of 'this' ;)

Answer 2

I do know getElement method, so except that..
