Checkbox click not working from within unordered list item

阅读更多关于 Checkbox click not working from within unordered list item

问题 I am unable to 'check' an input checkbox that is embedded in an expandable UL. I know the reason has something to do with click binding but I just can't figure it out. The UL is dynamic so I add new li's and UL's. The lowest level UL contains lis that should be selectable.

Is there a way to solve this problem, or are there any workarounds? 回答1: You have to redraw the tree itself, or create an empty node and simply remove it when the

问题 I have some questions about expandable ads and <iframe> s. I've created expandable ads which will displayed in <iframe> s. These ads will be served by known adservers like doubleclick, smartadserver, eyewonder, etc. Thanks to some questions on Stack Overflow, I've discovered that they are some ways to break the ads out of the <iframe> s or even to dynamically resize the <iframe> s. I've found <iframe> buster files from the main ad serving company on the Internet, but I don't really get how
