Play the Web value jquery (i)---batch processing of one label in the form (for example, input)

jquery can manipulate a form to manipulate a label in bulk, as an example of the input tag.

Example one: All readonly properties of input to delete infoform form

$ ("#infoForm input"). Removeattr ("ReadOnly");

Example two: Modifying the ReadOnly property of all input for the Infoform form

$ ("#infoForm input"). attr ("ReadOnly", true);

Example three: Change a value in input to a Z

     $ ("#infoForm input"). each (function () {           this.value = This.value.replace ("A", "Z");     

Of course, there are other things you can do, just explain how to do batch processing, and you can manipulate other tags.
