javascript字符串与数组转换汇总
数组转字符串
1.join()方法
vars=["a","d","a","f","g","f","s","g"];
s.join()//"a,d,a,f,g,f,s,g"
s.join("")//"adafgfsg"
s.join('');//adafgfsg
字符串转数组
1.call()方法
varstr="adafgfsg"; varstrArr=Array.prototype.slice.call(str,0); console.log(strArr);
结果：["a","d","a","f","g","f","s","g"]
2.正则表达式
varstr="adafgfsg";
varstrArr=str.replace(/(.)(?=.)/g,'$1,').split(',');
console.log(strArr);
varstr="adafgfsg";
varstrArr=str.match(/\w/g);
console.log(strArr);
结果：["a","d","a","f","g","f","s","g"]
3.直接用split()方法
varstr="adafgfsg";
varstrArr=str.split('');
console.log(strArr);
结果：["a","d","a","f","g","f","s","g"]
