Question

我问的原因是，当我在render()中只有一个参数时，似乎工作得很好但是当我添加第二个时，它会抛出一个Uncaught SyntaxError: Unexpected token }。

这是我的代码：

create.ejs [JS]

if (url.indexOf('?alert') != -1) {
    Alert.render('Record has been created!', 'Create');
}

customAlert.js

var Alert = new CustomAlert();
function CustomAlert() {
    this.render = function(body, head) {
        var winW = window.innerWidth;
        var winH = window.innerHeight;
        var dialogOverlay = document.getElementById('dialogOverlay');
        var dialogBox = document.getElementById('dialogBox');

        dialogOverlay.style.display = "block";
        dialogBox.style.left = (winW/2) - (550 * 0.5) +"px";
        dialogBox.style.top = "200px";
        dialogBox.style.visibility = "visible";
        document.getElementById('dialogBoxHead').innerHTML = head;
        document.getElementById('dialogBoxBody').innerHTML = body;
        document.getElementById('dialogBoxFoot').innerHTML = '<button    id="customBtn" onclick="Alert.ok(' + JSON.stringify(head) + ')">OK</button>';
    };
    this.ok = function(selected){
        document.getElementById('dialogBox').style.display = "none";
        document.getElementById('dialogOverlay').style.display = "none";
        if (selected != 'Oops!') {
            location.replace("http://localhost:3000/software");
        } else {
            location.replace("http://localhost:3000/home");
        }
    };
}

它会在create:2上抛出异常，这只是<html>标记吗？知道为什么会这样吗？还值得一提的是，我有另一个名为customDelete.js的自定义提醒，它按预期工作，但只传递1个参数render()

是否有多少参数可以传递给.render（）？ [使用Javascript]
