我正在尝试第一次在Java脚本中实现鸭子输入,以避免冗长的条件语句。以下是我的鸭子输入代码
// A simple array where we keep track of things that are filed.
filed = [];
function fileIt(thing) {
// Dynamically call the file method of whatever
// `thing` was passed in.
thing.file();
// Mark as filed
filed.push(thing);
}
function AuditForm(reportType) {
this.reportType = reportType;
}
AuditForm.prototype.file = function () {
console.log("Hello from Here!!!");
//Call Ajax here and then populate grid
}
var AuditForm = new AuditForm("AuditForm");
这就是我的称呼
fileIt("AuditForm");
使用上面的代码,我能够命中fileIt(thing)函数,但是在
thing.file();
处出现未知错误这是怎么了..建议。
最佳答案
var auditForm = new AuditForm("AuditForm");
fileIt(auditForm);
您正在将字符串传递给
fileIt
而不是具有file()
函数的字符串。
