Question

我有以下字符串说：

var str = "This is 'first text' and now this is 'second', and many more contents goes here.";

现在，我希望将前两个引号first text与some text之间的文字替换为其他两个引号，并使用second和some more text等文本替换

最后一个字符串应该是这样的：

This is 'some text' and now this is 'some more text', and many more contents goes here.

实际上我必须在两个文本框的文本更改事件中进行这两个替换。到目前为止，我只能用特定的文字替换，而不是以上条件。

如果您想根据文字匹配替换内容，请尝试

var str = "This is 'fisrt text' and now this is 'second', and many more contents goes here.";

var map = {
    "'fisrt text'": "'some text'",
    "'second'": "'more text'"
}

var str2 = str.replace(/'.*?'/g, function (str) {
    return map[str] || ''
});
console.log(str2)

如果您想用位置（索引）替换它

var str = "This is 'fisrt text' and now this is 'second', and many more contents goes here.";

var array = ["'some text'",
    "'more text'"],
    i = 0;

var str2 = str.replace(/'.*?'/g, function (str) {
    return array[i++] || ''
});
console.log(str2)
