A description of how jquery assigns values to Val and ATRR ("value")

When I do the project, I pass the data from the background to assign a value to a text box, through Google Browser,

When the change found no changes, and finally looked up the reason, it was jquery in the Val and ATRR ("value", the difference between the browser,

So the summary is as follows:

The use of Val () and ATRR (' value ') in jquery, assuming there is a default value, if you assign a value with Val (), then when this is worth changing, Google can't get the latest value, but IE can,

For ATRR (' value ' if there is a default value, then when changing this is worth it, ie and Google can get the latest changes, currently on IE and Google testing, other browsers do not test. Ha ha
