我试图在单击按钮时调用函数,但由于某些原因,按钮不会调用该函数。Dreamweaver没有显示任何语法错误。有人能告诉我为什么按钮失灵吗?

不幸的是,错误太多,很难知道从哪里开始。你的问题的第一个答案是按钮什么都没做,因为你的代码没有编译。我不知道为什么Dreamweaver没有报告错误。Chrome的开发工具非常乐意这样做
这是一个"工作"版本:

imgObj1 = document.getElementById('blue');
imgObj1.style.position = 'relative';
imgObj1.style.left = '0px';
}
function moveRight(){
var redPosition = parseInt(imgObj.style.left);
imgObj.style.left = redPosition + Math.floor((Math.random() * 20) + 1) + 'px';
var bluePosition = parseInt(imgObj.style.left);
imgObj1.style.left = bluePosition + Math.floor((Math.random() * 20) + 1) + 'px';
if (redPosition >= 1000 || bluePosition >= 1000)
{
if (redPosition >= 1000) {
alert("The Red Car has won the Race!");
