Get percentage of scroll position

问题 The problem: What would be the mathematical formula to calculate (regardless of the scrollHeight of the document) how far the bottom of the scrollbar is from it's total bottom (which would be the end of the page). So, for example, when the scrollbar is at the top, I would say the distance in percentages of the bottom of it, from the bottom of the document, would be 0% , and when it's totally scrolled all the way (vertically), it would be 100% . My goal: My goal is to calculate how many pixels

Scroll inside the table

问题 I have a simple html table inside a page, all I need is to make this table scrollable from inside and keep the table header static. I also need to make this table fit the whole screen, so the footer is visible. I don't need to specify a static height, as this screen will be displayed on high resolutions and it makes no sense to apply specific height in pixels. Here is the fiddle sample: http://jsfiddle.net/3L4zb7cf/ Code: <div class="container"> <table class="containertbl"> <tr> <td> <div
