语法

+ +
str.trimEnd();
+str.trimRight();
+ +

返回值

+ +

一个新字符串,表示从调用字串的末(右)端除去空白。

+ +

描述

+ +

trimEnd() / trimRight()方法移除原字符串右端的连续空白符并返回,trimEnd() / trimRight()方法并不会直接修改原字符串本身。

+ +

别名

+ +

为了与 {{jsxref("String.prototype.padEnd")}} 等函数保持一致,标准方法名称为trimEnd。 但是,出于Web兼容性原因,trimRight仍然是trimEnd的别名。 在某些引擎中,这意味着:

+ +
String.prototype.trimRight.name === "trimEnd";
+
+ +

示例

+ +

使用trimEnd()

+ +

下面的例子输出了小写的字符串"   foo":

+ +
var str = "   foo  ";
+
+alert(str.length); // 8
+
+str = str.trimRight();  // 或写成str = str.trimEnd();
+console.log(str.length); // 6
+console.log(str);       // '   foo'
