jQuery Height Altimeter

由 落花浮王杯 提交于 2021-01-28 18:50:23
问题 I would like to know it would be possible to create a sort of altimeter / counter display that dyamically changes the counter as you scroll.

javascript enable a disabled textbox after a while

由 Deadly 提交于 2021-01-28 18:32:28
问题 I've been trying all sorts of things and looking for an answer. I found some but they don't work for some strange reason. I'm using a txt document to store an array and using ajax to GET from it. It works that after you failed 3 attempts it disables the fields, but how do I make it so that after 10 seconds it enables again?

how to store and reuse a timeout in a jQuery event handler?

由 一笑奈何 提交于 2021-01-28 18:30:40
