Question

我创建了一个似乎有效的函数，直到我开始向.js文档添加更多函数。

这是html ..

<input id="nameSearch" type="text"/>
<input type="button" value="Search" onclick="search();"/>

这是js ..

 function search(){
        var bName = document.getElementById("nameSearch").value;
        alert(bName);
    };

这一直有效，直到我向外部.js文档添加新函数。我还没有在html文件中使用任何这些函数，所以我不确定它们为什么会影响它。

function business(b_name,add_1,add_2,city,state,zip,phone){
    this.b_name = b_name,
    this.add_1 = add_1,
    this.add_2 = add_2,
    this.city = city,
    this.state = state,
    this.zip = zip,
    this.phone = phone,
};

var ADW = new business("xxx", "xxx", "xxx", "Tucson", "AZ", "xxx", "xxx-xxx-xxxx");

var PC = new business("xxx", "xxx", "xxx", "Tucson", "AZ", "xxx", "xxx-xxx-xxxx");

var contacts = [ADW, PC];

Answer 1

这是因为您的business功能中存在错误。

我相信你正在寻找分号而不是逗号：

function business(b_name,add_1,add_2,city,state,zip,phone){
    this.b_name = b_name;
    this.add_1 = add_1;
    this.add_2 = add_2;
    this.city = city;
    this.state = state;
    this.zip = zip;
    this.phone = phone;
};

从高层次看，您似乎正在尝试定义对象并使用business函数作为初始化方法。您可能希望这样做：

let business = {
    b_name: b_name,
    add_1: add_1,
    add_2: add_2,
    city: city,
    state: state,
    zip: zip,
    phone: phone
};

Answer 2

如果你在控制台中查看，你会看到这个错误：

SyntaxError: expected expression, got '}'

它甚至会告诉你哪一行是问题！

您的问题是，您没有使用分号在函数中终止行，您已使用过逗号。

这是正确运行的修复程序：

function business(b_name,add_1,add_2,city,state,zip,phone){
    this.b_name = b_name;
    this.add_1 = add_1;
    this.add_2 = add_2;
    this.city = city;
    this.state = state;
    this.zip = zip;
    this.phone = phone;
}

var ADW = new business("xxx", "xxx", "xxx", "Tucson", "AZ", "xxx", "xxx-xxx-xxxx");

var PC = new business("xxx", "xxx", "xxx", "Tucson", "AZ", "xxx", "xxx-xxx-xxxx");

var contacts = [ADW, PC];

在a Fiddle，你可以看到它在哪里运行。

添加更多功能后，功能停止工作
