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)
}
