JavaScript错误显示“确认不是函数"，提示“不是函数". [英] JavaScript error says "confirm is not a function"

问题描述

提交表单时，我正在使用带有验证插件的jQuery:

I'm using jQuery with the validation plugin when I submit a form:

$('.frmProject:visible').validate( {

    errorContainer: ".site_details:visible .messageBox1",
    errorLabelContainer: ".site_details:visible .messageBox1 span.messagehere",
    invalidHandler: function(form, validator) {
    },

    rules: {
        site_id: {
            required: true,
        }
    },
    messages: {
        site_id: "Project has no assigned site information. Click the marker on the map at left to specify the site where this project took place."
    },
    submitHandler: function(data) {
        SaveProject();
    }

});

在submitHandler中，

In the submitHandler,

function SaveProject(){
    //... load variables with input contents
    $.ajax({
        url: 'ajax/save_project.php',
        dataType: 'json',
        data: 'id='+id+'&title='+title+'&project='+project+'&sector='+sector+'&volunteer='+volunteer+'&lat='+lat+'&lng='+lng+'&name='+name+'&mun='+mun+'&prov='+prov,
        success: function(data) {
            //... load 'messages' object with stuff
            $.each(messages, function(key, value) {
                if (confirm(key)){
                    console.log(item);
                }
            });
        }
    });
}

当我提交经过验证的表单并到达每个循环中的确认时，我收到错误消息:确认不是函数".

When I submit the validated form and it gets to the confirm inside the each loop, I get the error message: "confirm is not a function".

如何向用户显示消息以进行确认?

How can I present a message to the user for confirmation?

当我在控制台中输入"confirm"时，我得到以下提示:

When I type "confirm" into the console I get this:

检查DOM会发现:

窗口> Confirm()没有可显示该对象的属性.

在Script中进行检查会将我带到jquery-1.6.2.min.js中的一个地方

Inspecting in Script takes me to a place in jquery-1.6.2.min.js

推荐答案

如果分配不带var的变量，则将该变量分配给全局空间.在您的情况下，为确认变量分配了一个字符串，该字符串将覆盖本机的确认方法.

If you assign a variable without var, you are assigning that variable to the global space. In your case there was a string assigned to the confirm variable that overrode the native confirm method.
