解决方法
暂时显示()一个元素来检索孩子的身高似乎工作正常.
HTML:
<div id="target" style="display:none;"> <!-- Add a background color to see if it's noticeable --> <div style="height:123px; background:#000;"></div> </div>
JS:
// Show the hidden parent of the element we want the height of $("#target").show(0,function(){ // Find and grab the height of the element we want the_height = $(this).find("div").height(); // Hide parent and display child's height after it }).hide().after(the_height);
