在此页

toLocaleString() method returns a string representing the elements of the typed array. The elements are converted to strings and are separated by a locale-specific string (such as a comma “,”). This method has the same algorithm as Array.prototype.toLocaleString() and, as the typed array elements are numbers, the same algorithm as Number.prototype.toLocaleString() applies for each element. TypedArray is one of the typed array types here.

句法 

typedarray.toLocaleString([locales [, options]]);

参数

locales and options arguments customize the behavior of the function and let applications specify the language whose formatting conventions should be used. In implementations, which ignore the locales and options arguments, the locale used and the form of the string returned are entirely implementation dependent.

见 Intl.NumberFormat() 构造函数 for details on these parameters and how to use them.

返回值

A string representing the elements of the typed array.

范例

使用 toLocaleString 

var uint = new Uint32Array([2000, 500, 8123, 12, 4212]);
uint.toLocaleString();
// if run in a de-DE locale
// "2.000,500,8.123,12,4.212"
uint.toLocaleString('en-US');
// "2,000,500,8,123,12,4,212"
uint.toLocaleString('ja-JP', { style: 'currency', currency: 'JPY' });
// "￥2,000,￥500,￥8,123,￥12,￥4,212"
