我需要从 html 调用一个 javascript 函数，但它似乎不起作用。我点击图像，没有任何反应。变量“brushVar”似乎没有改变。blue.png 是一个蓝色的小按钮，而 blueN.png 是一个蓝色的小按钮，具有不同的蓝色阴影，等等......非常感谢任何帮助

<body>

<script>
var brushVar;


function blue() {
    brushVar = ("#000000");
    alert(brushVar);
}

function blueN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function cyan() {
    brushVar = ("#000000");
    alert(brushVar);
}

function cyanN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function green() {
    brushVar = ("#000000");
    alert(brushVar);
}

function greenN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function purple() {
    brushVar = ("#000000");
    alert(brushVar);
}

function purpleN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function red() {
    brushVar = ("000000");
    alert(brushVar);
}

function redN() {
    brushVar = ("000000");
    alert(brushVar);
}

function yellow() {
    brushVar = ("#000000");
    alert(brushVar);
}

function yellowN() {
    brushVar = ("#000000");
    alert(brushVar);
}
</script>





<div id="buttons" style="position:absolute; width:100%; height:100%>
 <a href="#" onclick="blue()';" >
    <img src="/blue.png"/>

<a href="#" onclick="blueN()';" >

您的 javascript 必须用脚本标记括起来，并且您的字符串必须用引号引起来：

<div id="over" style="position:absolute; width:100%; height:100%>
 <img src="blue.png" href='' onclick='blue();'>
 <img src="blue.png"  href='' onclick='blue();' >
 <img src="blueN.png"  href='' onclick='blueN();' >
 <img src="cyan.png" href='' onclick='cyan();' >
 <img src="cyanN.png" href='' onclick='cyanN();'>
 <img src="green.png" href='' onclick='green();' >
 <img src="greenN.png" href='' onclick='greenN();'>
 <img src="purple.png" href='' onclick='purple();'>
 <img src="purpleN.png" href='' onclick='purpleN();'>
 <img src="red.png" href='' onclick='red();'>
 <img src="redN.png" href='' onclick='redN();'>
 <img src="yellow.png" href='' onclick='yellow();'>
 <img src="yellowN.png" href='' onclick='yellowN();'>
</div>

<script type="text/javascript">
    var color;

    function blue() {
        color = "blue";
    }

    function redN() {
        color = "red-N";
    }
</script>
