VAR设置为true /在切换功能虚假 [英] Set var to true/false in toggle function

问题描述

我有一个按钮，我想我的变量点击设置为真正按钮被按下时，和假再次单击该按钮时（我想切换功能）。

I have a button and I want my variable click to be set to true when the button is clicked, and false when the button is clicked again (I want toggle functionality).

在点击==真，我希望它的输出点击到控制台，当点击==虚假我希望它的输出未点击。

When click == true, I want it to output clicked into the console and when click == false I want it to output not clicked.

var click = false

下面是我的切换功能：

$('.button').toggle(
    function(){
        click = true;
        $('.bmw').show();

    }, function() {
        click = false;
        $('.bmw').hide();

    });

和我想要它做什么：

if(click = true) {
    console.log('clicked');
} else {
    console.log('not clicked');
}

当我打开控制台显示未点击的页面，但是当我preSS的按钮，它不切换到真实。宝马对象** .bmw 然而就显示和隐藏，当我切换按钮，这似乎是工作的罚款。

When I load the page the console shows not clicked but when I press the button it doesn't switch to true. The bmw objects** .bmw do however show and hide when I toggle the button so that seems to be working fine.

我在做什么错了？

推荐答案

您正在分配比较不点击的价值

You are assigning not comparing the value of click

您应该 == 不是 =

if(click == true) {
    console.log('clicked');
} else {
    console.log('not clicked');
}

然而，你甚至都不需要使用如果（点击==真）。您可以在实际上只使用如果（点击）代替。

However you do not even need to use if(click == true). You can in fact just use if(click) instead.

编辑：从我们在评论中讨论它看起来像你只有一次当code是第一次运行调用if语句，而不是每次你切换。我建议创建的if语句一个单独的函数中，然后调用切换的两个部分此方法。

From what we discussed in the comments it looks like you were calling the if statement only once when the code was first run, not everytime you toggled. I suggest creating a seperate function with the if statement inside, then calling this method in both parts of the toggle.
