如何在类jquery的基础上获得ul的宽度？

Question

How can get width of <ul> on the class name as class name will be unique for each <ul> .

I don't want to select by id , but rather by class so it can be reused,

My <ul> html is:

<ul id="cat-sec-bar" class="RestaurantssubTypeDivClass" style="display: block;">
    //some code here
</ul>

I am trying with this:

 var divWidth = $(".RestaurantssubTypeDivClass").width();
 //Getting 0

What is wrong here? any other way to do it?

Answer 1

试试这个：

var divWidth = $(".RestaurantssubTypeDivClass").css('width');

Answer 2

actually there will be many ul shortlisted in basis of class so you ll have to take widths in array , then you need to precess array :

Class can be Duplicate. Id's are Unique.

 var divWidth = [];

$(".RestaurantssubTypeDivClass").each( function(){

 divWidth.push(  $(this).width());

})
