Let's take a look at an example to see what a modal window is.
The following is the QQ Show Mall in the non-login prompts a state of login. When I am in the non login state, by saving the image of the way to buy a dress, pop-up Login dialog window prompts to log in. At this point, the Login dialog Window Lock Mall page, lock ie, only when the login window to operate, you can do other operations. For example: Minimize IE, browse Mall and so on. We can say that the Login dialog window is a modal window.
Modal windows often give people "bad" impressions, why "bad"? Because it's "long" like that? Or because it's usually useless, so users don't look at the content? If you change to a floating layer div, does it become "good"? We discussed the form of the modal window and the "good or bad" problem.
Why do people think it's "bad"?
Sibe: "The previous System pop-up dialog box, users can not understand, or do not look, to the user's impression is mostly a warning." So the feeling is very bad, to the user speaking, very violent. "(hehe, can cite the recent popular, very Chen, very crown Greek." Eele: "When I fill in some registration information, I need to copy some content from another page, this time pop-up alert cannot go to another page." (I have also encountered ~ ~) Hiseven: "There have been some sites, bugs, pop-up ' countless ' OK dialog box, must be all determined to do the next step, so start clicking on one after another to determine." "(well, especially the kind that lets me click on a continuous set, but keep popping up on the sort of spam site that keeps me near the brink of collapse ~ ~)
Smelly fish: "There is more than one fork button on the screen, but only one can be clicked, such as Photoshop." ”
