javascript - JS/jQuery - 关于创建可在多个函数中使用的变量的建议

Question

我想创建一系列如下变量，每个变量都有设置:

var panel_myfeed = new Array();
panel_myfeed[0]="/myfeed";
panel_myfeed[1]="#view-panel-myfeed";
panel_myfeed[2]="XXXXXXXX";

var panel_OtherPanel = new Array();
panel_OtherPanel[0]="/otherurl";
panel_OtherPanel[1]="#other-url-panel";

var panel_OtherPanel2 = new Array();
panel_OtherPanel2[0]="/otherurl2";
panel_OtherPanel2[1]=".other-url-panel2";

然后我想要两个单独的函数可以使用这些变量

function WhichPanel(url) {
  *** Given a URL var like /myfeed, which which panel[0] this belongs to so I can get the other variables
  ** do something now that I have the settings above
}

function KillPanel(url) {
  *** Given a URL var like /myfeed, which which panel[0] this belongs to so I can get the other variables
  ** do something now that I have the settings above
}

建议？谢谢

对象映射在这里是最简单的，如下所示:

var panels = { "/myfeed": "#view-panel-myfeed", 
               "/otherurl": "#other-url-panel",
               "/otherurl2": ".other-url-panel2" }

然后在您的函数中，您只需执行 panels[url] 即可获取与其配套的选择器。如果您需要其他属性，只需使用对象代替值，如下所示:

var panels = { "/myfeed": { selector: "#view-panel-myfeed", other: "value" }, 
               "/otherurl": { selector: "#other-url-panel" },
               "/otherurl2": { selector: ".other-url-panel2" } }

然后要获取选择器，它是 panels[url].selector，其他属性的 .property 等。
