点击多个div时交换图像

标签: jquery if-statement replace swap

我被要求为this page添加另一种颜色选项。如果您点击马赛标志,卡车将从橙色变为蓝色;如果再次单击它会变回橙色。如果单击右侧的探索标志,则可以使用两个视图,这两个视图也具有交换的图像颜色。

我想在页面中添加一个新的div,使其变黄。所以蓝色按钮应该从黄色或橙色变为蓝色,如果在蓝色时单击则变回橙色。黄色按钮应从蓝色或橙色变为黄色,然后变回橙色 蓝色按钮不应使卡车变黄,黄色按钮不应使其变为蓝色。

如果有人点击了探索,则所选颜色需要保留。

以下是使图像交换的原始jQuery:

        var isOrange = true;
        $("#marseilleBtn").click(function(){
         $("img.img-swap").each(function(){
                    if(isOrange){
                        this.src = this.src.replace("_orange","_blue");
                    } else{
                        this.src = this.src.replace("_blue","_orange");
                    }
         });
         if(isOrange){
             isOrange = false;
         } else {
             isOrange = true;
         }
    });

我没有编写这段代码,而且我是jQuery的新手,所以这对我来说很有挑战性。我写了这段代码,它几乎可以工作。问题是,如果黄色卡车打开,我点击蓝色标志,它不会改变颜色。此外,如果蓝色卡车打开,我点击黄色标志,它不会改变颜色。如果我从橙色开始,它只会改变颜色...希望这是有道理的。

        var isOrange = true;
        $("#marseilleBtn").click(function(){
         $("img.img-swap").each(function(){
                    if(isOrange){
                        this.src = this.src.replace(("_orange") || ("_soleil"),"_blue");
                    } else{
                        this.src = this.src.replace("_blue","_orange");
                    }
         });
         if(isOrange){
             isOrange = false;
         } else {
             isOrange = true;
         }
    });

        var isOrange = true;
        $("#soleilBtn").click(function(){
         $("img.img-swap").each(function(){
                    if(isOrange){
                        this.src = this.src.replace(("_orange") || ("_blue"),"_soleil");
                    } else{
                        this.src = this.src.replace("_soleil","_orange");
                    }
         });
         if(isOrange){
             isOrange = false;
         } else {
             isOrange = true;
         }
    });

任何人都可以帮我实现我想做的事吗?如果你也知道更好的事情,我会采取完全不同的方法......走这条路是因为我从我给出的代码开始。我也尝试创建一个OR语句,但这根本不起作用,不确定原因:

    this.src = this.src.replace(('_orange, _yellow'),'_blue');

奖金问题!我对此代码的第一部分感到困惑,它将变量isOrange声明为true,然后在结尾处声明if / else语句为false。谁能为我打破这个?我理解图像交换的一部分......

         if(isOrange){
             isOrange = false;
         } else {
             isOrange = true;
         }
    });

提前感谢您的帮助。

更新:

对此进行操作,但需要额外点击才能在更改两次后更改颜色。即点击马赛,转蓝。点击马赛,变成橙色。单击单击以返回马赛。

和奖金回答!!!第一个var color是deafult颜色,是橙色...结束if / else条件是beacuse sine你也有三个图像Explore ..你需要一个循环和循环你正在chekcing颜色...所以在第一次调用..橙色是颜色,所以它chnages为蓝色(运行循环3次..)然后来到这个if / else条件,将值颜色更改为蓝色...在第二次单击。因为现在颜色是蓝色..循环将其变为黄色......依此类推......

首先,跳到我身边的是你两次同样的功能。

你也可以这样对待它:

var isOrange = true;
$("#marseilleBtn, #soleilBtn").click(function () {
    $("img.img-swap").each(function () {
        if (isOrange) {
            this.src = this.src.replace(("_orange") || ("_soleil"), "_blue");
        } else {
            this.src = this.src.replace("_blue", "_orange");
        }
    });
    if (isOrange) {
        isOrange = false;
    } else {
        isOrange = true;
    }
});

if(isOrange)else isOrange = false;告诉我,swithc的颜色是什么。因此,如果要添加第三种颜色,则不能再使用简单的布尔值,因为它只有两个值。为了保持代码清晰,我会使用一个字符串。

您的代码可能如下所示:

var curentColor = "orange";
$("#marseilleBtn, #soleilBtn").click(function () {
    $("img.img-swap").each(function () {
        if (curentColor === "orange") {
            this.src = this.src.replace("_orange", "_blue");
            curentColor = "blue";
        } else if(curentColor === "blue") {
            this.src = this.src.replace("_blue", "_yellow");
            curentColor = "yellow";
        } else if(curentColor === "yellow") {
            this.src = this.src.replace("_yellow", "_orange");
            curentColor = "orange";
        }
    });
});

这会将颜色从橙色变为蓝色再变为黄色,然后再变回橙色,完成色圈。
