2. jquery1.11.1 checkbox
Front-end js Code:

// Select all function CheckAll (e) {if ($ (e ). attr ("checked") = "checked") {$ (e ). removeAttr ("checked"); $ (": checkbox [name = 'cbxstudent ']"). removeAttr ("checked");} else {$ (e ). attr ("checked", true); // Add attribute $ (e ). prop ("checked", true); // equivalent to refreshing the page $ (": checkbox [name = 'cbxstudent ']"). attr ("checked", true); // Add attribute $ (": checkbox [name = 'cbxstudent ']"). prop ("checked", true); // equivalent to refreshing the page} // single-choice function CheckOne () {var checkNums = $ (": checkbox [name = 'cbxstudent '] "). length; // The total number of checkboxes var checkedNums =$ (": checkbox [name = 'cbxstudent ']: checked "). length; // The total number of checkboxes selected if (checkNums = checkedNums) {$ ("# cbxStudentAll "). prop ("checked", true); // equivalent to refreshing the page} else {$ ("# cbxStudentAll "). removeAttr ("checked ");}}

The checked attribute of the attr method is not changed, but the property of the prop method is changed, and the checkbox of the page is not checked. The combination of the two methods is normal, which may be a version issue.
