语法解释: $("#select_id").change(function(){//code...}); //为Select添加事件,当选择其中一项时触发 var checkText=$("#select_id").find("option:selected").text(); //获取Select选择的Text var checkValue=$("#select_id").val(); //获取Select选择的Value
1. var old = $("#old").val(); if (old != null && old != 'undefined' && old != '') { var Gbox=$("input:checked[id^='"+old+"']"); //获取id以 old的值开头并且被选中的checkbox对象 for(var i=0;i<Gbox.length;i++){ if (Gbox[i])
input type=checkbox的值是on或off 实体类中这样写即可 public void setChapterVisibility(Object chapterVisibility) { if (chapterVisibility.equals("on")) this.chapterVisibility = 1; else if (chapterVisibility.equals("off")) this.chapterVisibility = 0; e
