Question

我有

function librarytech(humanity,food,wood,metal,wealth)
{
this.humanity=humanity;
this.food=food;
this.wood=wood;
this.metal=metal;
this.wealth=wealth;
}

然后我构建一些：

var library_science1=new librarytech(0,200,200,0,0);
var library_science2=new librarytech(0,4000,0,0,4000);
var library_science3=new librarytech(0,30000,0,0,30000);

然后我有这个.click功能：

$("[id^='library_']").click(function() {
if (humanity >= this.humanity){

humanity -= this.humanity;
food -= this.food;
wood -= this.wood;
metal -= this.metal;
wealth -= this.wealth;

}});

相关HTML的位置如下：

<span id="library_science1"></span>
<span id="library_science2"></span>
<span id="library_science3"></span>

然而它不起作用，我没有收到任何我能看到的错误：/有什么建议吗？（在这些情况下，变量'Humanity'大于0，所以它应该有效吗？

我宁愿使用数组：

DOM：

<ul id="libraries-science">
    <li>1</li>
    <li>2</li>
    <li>3</li>
</ul>

JS：

function librarytech(humanity,food,wood,metal,wealth)
{
    this.humanity=humanity;
    this.food=food;
    this.wood=wood;
    this.metal=metal;
    this.wealth=wealth;
}

var librariesScience = [];
librariesScience.push(new librarytech(0,200,200,0,0));
librariesScience.push(new librarytech(0,4000,0,0,4000));
librariesScience.push(new librarytech(0,30000,0,0,30000));

$('ul#libraries-science > li').click(function () {
    var libraryScience = librariesScience[$(this).index()];
    // do your stuff here
});

让jQuery'以'选择器开始使用构造的对象
