今天由我亲自给大家总结

javascript内置对象有哪些？

reg正则,booer,math,string,arr,obj,number,date,function,window全局，error，json

在这些对象的原型上有一些方法，可以到这个网站查看http://lzw.me/pages/ecmascript/。

我下面罗列一些比较有用的

对数组的操作方法，

Array.prototype.toString ( )

Array.prototype.toLocaleString ( )

Array.prototype.concat ( [ item1 [ , item2 [ , … ] ] ] )

Array.prototype.join (separator)

Array.prototype.push ( [ item1 [ , item2 [ , … ] ] ] )

Array.prototype.pop ( )

Array.prototype.reverse ( )

Array.prototype.reduceRight ( callbackfn [ , initialValue ] )

Array.prototype.reduce ( callbackfn [ , initialValue ] )

Array.prototype.shift ( )

Array.prototype.slice (start, end)

Array.prototype.sort (comparefn)

Array.prototype.forEach ( callbackfn [ , thisArg ] )

Array.prototype.every ( callbackfn [ , thisArg ] )

Array.prototype.some ( callbackfn [ , thisArg ] )

Array.prototype.lastIndexOf ( searchElement [ , fromIndex ] )

Array.prototype.indexOf ( searchElement [ , fromIndex ] )

Array.prototype.unshift ( [ item1 [ , item2 [ , … ] ] ] )

Array.prototype.splice (start, deleteCount [ , item1 [ , item2 [ , … ] ] ] )

Array.prototype.map ( callbackfn [ , thisArg ] )

Array.prototype.filter ( callbackfn [ , thisArg ] )

对字符串的操作方法

String.prototype.toString ( )

String.prototype.trim ( )

String.prototype.toLocaleUpperCase ( )

String.prototype.toUpperCase ( )

String.prototype.toLocaleLowerCase ( )

String.prototype.toLowerCase ( )

String.prototype.substring (start, end)

String.prototype.split (separator, limit)

String.prototype.slice (start, end)

String.prototype.search (regexp)

String.prototype.replace (searchValue, replaceValue)

String.prototype.match (regexp)

String.prototype.localeCompare (that)

String.prototype.lastIndexOf (searchString, position)

String.prototype.indexOf (searchString, position)

String.prototype.valueOf ( )

String.prototype.concat ( [ string1 [ , string2 [ , … ] ] ] )

String.prototype.charAt (pos)

String.prototype.charCodeAt (pos)

String.prototype.substr(start, length)

math

max ( [ value1 [ , value2 [ , … ] ] ] )

min ( [ value1 [ , value2 [ , … ] ] ] )

pow (x, y)
