技術標籤：every和some

不要低頭，皇冠會掉

every 只要都是true才為true，有一個值為false就為false，
some與every正好相反，只要有一個值為true，都為true

every 用法

//為true
var arr = [{archive_tree_name: "產權證",jianZhiDangAnYuanIsDelete: true},{archive_tree_name: "產權證1",jianZhiDangAnYuanIsDelete: true},{archive_tree_name: "產權證2"
 
,jianZhiDangAnYuanIsDelete: true}];
arr.every(function(x) {
     return x.jianZhiDangAnYuanIsDelete == true
});

//false
var arr = [{archive_tree_name: "產權證",jianZhiDangAnYuanIsDelete: false},{archive_tree_name: "產權證1",jianZhiDangAnYuanIsDelete: true},{archive_tree_name: "產權證2"
 
,jianZhiDangAnYuanIsDelete: true}];
arr.every(function(x) {
     return x.jianZhiDangAnYuanIsDelete == true
});

some用法

var arr = [{archive_tree_name: "產權證",jianZhiDangAnYuanIsDelete: false},{archive_tree_name: "產權證1",jianZhiDangAnYuanIsDelete: true},{archive_tree_name: "產權證2"
 
,jianZhiDangAnYuanIsDelete: true}];
arr.some(function(x) {
     return x.jianZhiDangAnYuanIsDelete == true
});
