This isn't an error related to jQuery - it's the fact that you're trying to run a string instance's method that doesn't exist. A quick search gives me another StackOverflow answer, which happily implements String#formatfor you.
这不是与 jQuery 相关的错误 - 这是您尝试运行不存在的字符串实例方法的事实。快速搜索为我提供了另一个 StackOverflow 答案，它很高兴String#format为您实现。
String.prototype.format = function() {
var str = this;
for (var i = 0; i < arguments.length; i++) {
var reg = new RegExp("\{" + i + "\}", "gm");
str = str.replace(reg, arguments[i]);
}
return str;
}
Just paste that at the top or near to the top of your script file and use your newly-created function like "the {0} jumps over the {1}".format("quick brown fox", "lazy dog");in the script.
只需将其粘贴到脚本文件的顶部或顶部附近，然后像"the {0} jumps over the {1}".format("quick brown fox", "lazy dog");在脚本中一样使用新创建的函数。
