# 参数处理
JS:
```
function plugin_mian_func(options){
var defaluts = {
opt1: ‘opt1‘,
opt2: ‘opt2‘,
opt3: {
opt3_1: ‘opt3_1‘,
opt3_2: ‘opt3_2‘,
}
};
// 覆盖插件默认参数
var options = (function(){
// IE不支持Object.assign
return Object.hasOwnProperty(‘assign‘) ? Object.assign({},defaluts,options) : (function(){
for(var name in options){
defaluts[name] = options[name];
}
return defaluts;
})(defaluts, options)
})(defaluts, options);
console.log(options);
}
// 测试
plugin_mian_func({opt1:‘user_opt1‘,opt3: {opt3_1: ‘user_opt3_1‘, opt3_3: ‘user_opt3_1‘}});
```
jQuery:
```
function plugin_mian_func(options){
var defaluts = {
opt1: ‘opt1‘,
opt2: ‘opt2‘,
opt3: {
opt3_1: ‘opt3_1‘,
opt3_2: ‘opt3_2‘,
}
};
// 使用jQuery.extend 覆盖插件默认参数
var options = $.extend({}, defaluts, options);
console.log(options);
}
// 测试
plugin_mian_func({opt1:‘user_opt1‘,opt3: {opt3_1: ‘user_opt3_1‘, opt3_3: ‘user_opt3_1‘}});
