Code$ ("Input[name= ' Radio_name '][checked]"). Val ();//Select the value of the selected radio
$ ("#text_id"). focus (function () {//code ...})//event triggered when object text_id gets focus
$ ("#text_id"). blur (function () {//code ...})//event triggered when object text_id loses focus

jquery Gets the value of the checkbox selection

value you need to traverse this collection
$ ($ ("Input[name= ' Checkbox_name '][checked]")).
Each (function () {arrchk+=this.value + ', ';}); /Traverse the collection of selected checkbox elements to get value values

$ ("Input[name= ' Checkbox_name ']"). attr
("Checked", $ ("#checkbox_id"). attr ("checked"));//According to the 3,4,5 bar, you can analyze the meaning of this code
$ ("#text_id"). Val (). Split (",");//Returns an array of value values of text as ', ' delimited

The above operation, in fact, is the use of jquery selector, I hope you have a solid grasp of the jquery selector knowledge.
