javascript - window.location 重定向后是否调用了垃圾收集器？

Question

假设我有 javascript:

/*getAttribute is mootools method for retrieving a named attribute*/
var companyNumber = button.getAttribute('data-company-number');

var payPoint = button.getAttribute('data-pay-point');

window.location = '/Payslip/ListPayslips/?companyNumber=' + companyNumber + '&payPoint=' + payPoint

delete payPoint;//is this necessary?
delete companyNumber;//is this necessary?

是否需要删除行？他们会被跟注吗？

Answer 1

没有必要，重定向后所有变量和实例都将被删除。
