Ajax| Solution | problem | cross-domain

Ajax (Dynamic Web site static) accompanied by the Goole, more and more sites began to use, in the open large Ajax (Dynamic Web site static) program will encounter a lot of problems, mainly in the following areas:

1. Cross-browser issues
2. Historical Retreat Status Problem

3. Cross-domain issues

Cross-browser issues because there are many new Kaiyuan frameworks that have been solved, we don't have to worry about that.

History back State problem we can use an array to save the history, and then the data village to the historical object, and can be resolved, and there are many Kaiyuan framework to support, so the problem is not very big.

Cross-domain problems are not a good solution, but there is a way to give some basic solutions for everyone to choose from:

I believe you must be very familiar with this way, here is not a detailed introduction.
2. Use the way of the IFRAME to set the refresh of the leaf, this way is only to obtain data to display, and can not really and get the data to interact, transform the cost of the Dynamic Data page, is not very desirable, the application is not a lot, I also ignore not to discuss.
3.

4. Using the script label, in this way, you can use real Ajax (Dynamic Web site static) to cross the domain, and can use the returned data, swearing very simple, in our background program after processing to the results are directly in the JavaScript way to return, Using variables that return data directly in our HTML can be a simple example
