Question

我在flash中有一个文本字段，其中包含以下字符串：

txtFld.text = " Mr. Suresh Kumar has written this article"

现在，我想要做的是，我想删除最后一个字，看起来像：

txtFld.text = " Mr. Suresh Kumar has written this"

请帮助，感谢

Answer 1

试试这个：

    var text = txtFld.text;   // Saving text field' value in temporary variable
    text = text.split(" ");   // Splitting it at space delimiter
    text.splice(text.length-1 , 1); // Throwing out the last word
    txtFld.text = text.join(" ");   // Concatenating whole thing back

Answer 2

您可以结合使用.slice()和.lastIndexOf()：

var base:String = "Mr. Suresh Kumar has written this article";

// Slice up until the last whitespace character.
var trunc:String = base.slice(0, base.lastIndexOf(" "));
trace(trunc);

因为AS2没有正则表达式支持，所以你应该确保预先修剪输入（从正面和结尾删除空格）。
