我正在制作一个网站,并尝试更改 active car 变量的值,即使单击分区后,该变量也不会更改,即使单击分区后,activecar 的值仍保持为 .blueimg
什么是不正确的?
actions.js file
var activecar=".blueimg";
$(".redimg").hide();
$(".greyimg").hide();
$(".silverimg").hide();
$(".red").click(function(){
hideshow(".redimg",activecar);
});
$(".blue").click(function(){
hideshow(".blueimg",activecar);
});
$(".grey").click(function(){
hideshow(".greyimg",activecar);
});
$(".silver").click(function(){
hideshow(".silverimg",activecar);
});
function hideshow(colour,activecar) {
console.log("before");
console.log(activecar);
$(activecar).hide();
$(colour).show();
activecar = colour;
console.log("After");
console.log(activecar);
}
This is my index.html file
<!doctype html>
<html lang="en">
<head>
<title>CollegeDunia</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<img src="./assets/blue.jpg" class="blueimg"/>
<img src="./assets/red.jpg" class="redimg"/>
<img src="./assets/grey.jpg" class="greyimg"/>
<img src="./assets/silver.jpg" class="silverimg"/>
<div>
<a class="blue">Blue</a>
</div>
<div >
<a class="grey"> Grey</a>
</div>
<div >
<a class="red">Red</a>
</div>
<div >
<a class="silver">Silver</a>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="actions.js"></script>
</body>
</html>
最佳答案
更改函数的参数名称。它与您的全局变量具有相同的名称。
function hideshow(colour, car) { //activecar changed to car
