从$.each()中访问我的this.rules变量的最佳方法是什么？任何解释为什么/如何也将有所帮助！
- app.Style = function(node) {
- this.style = node;
- this.rules = [];
- var ruleHolder = node.find('Rule');
- $.each(ruleHolder,function(index,value) {
- var myRule = new app.Rule($(ruleHolder[index]));
- this.rules.push(myRule);
- });
- console.log(this.rules)
- }
解决方法
存储对此的引用 – 例如 – 将其命名为self,然后再调用.each(),然后使用self.rules访问规则：
- app.Style = function(node) {
- this.style = node;
- this.rules = [];
- var ruleHolder = node.find('Rule');
- var self = this;
- $.each(ruleHolder,value) {
- var myRule = new app.Rule($(ruleHolder[index]));
- self.rules.push(myRule);
- });
- console.log(this.rules)
- }
