360 or Firefox cannot assign a value to document. getelemnetbyid (aa ). Then, use ajax to display the data and select the desired data. the data value is returned to the form document. getelementbyid (aa) = 11;
Previously, it could be implemented in IE6, but it cannot be implemented in 360 or Firefox, and it cannot be assigned a value,
If a friend has a better method, you can also introduce it. I haven't done a website for a long time. I still click the form, read the corresponding data using ajax, select it, and send it back to the form, and then search. I just want such a function.

Document. getelementbyid ('A'). value = 11;
Found the cause,
Then assign the value to it. document. getelementbyid ('A'). value = 11; IE6 is acceptable. IE7 or Firefox is not supported and must be changedIt seems that the previous rule is too nonstandard, so many parts are compatible ,.
