html+js觉问题总结

1. html 页面字符集

<meta charset='utf-8' />

2. js 截取当前URL中问号后面的字符串

var search = window.location.search;
console.log(search);

3. js 创建array对象

var arr = new Array();

4. js split() 用于将字符串分豁成数组

var str = 'a=1a&b=2b&c=3c';

var arr = str.split('&');

结果：["a=1a","b=2b","c=3c"]

5. js 数组转对象

var str = 'a=1a&b=2b&c=3c';

var arr = str.split('&');//数组

var obj = new Array();//创建数组对象

for(var i=0,len = arr.length;i<len;i++){//对象

　var tmp = arr[i].split('=');
     obj[tmp[0]] = tmp[1];

}
