onclick In Image永远不会被执行

我的图片有两个以下代码，问题是当点击时没有发生任何事情。 

<div style="float: left;"><input onload="setValue()" type="image" src="img/board new/blank.png" name="saveForm" class="btTxt submit" id="spinner" onclick="spin()" />  </div>

这是我的完整代码。

<html>

<style>

body {
    background-image: url(img/background4.png);
    background-size: 100% 100%;
    background-repeat: no-repeat;
}


</style>

<script>

var stop = false;
var spinResult;
var gameOver = false;
var oldHTML;
var newHTML;

function setValue() {

var rollResult = location.search.substr(location.search.indexOf("=")+1);
document.getElementById('own').innerHTML = "You own " + rollResult + " piece(s) on the board.";

}

function advanceSpinner(i) {
i = i || 1;

if (stop == false) {
if (i > 10) 
i = 1; // change this to return if you don't want to run forever
document.getElementById("spinner").src = "img/board new/" + i + ".png";
spinResult = i;
setTimeout(function () { advanceSpinner(i + 1) }, 50);
}
}



function spin() {

var start = Math.floor(Math.random() * (10 - 1 + 1)) + 1
advanceSpinner(start);
setTimeout(function () {stop = true;}, 4000);
setTimeout(function () {checkWin();}, 4050);

}

function checkWin() {
/*
if (rollResult == 1 && spinResult == 1) {
    alert("Win");
} else if (rollResult == 2 && spinResult == 1) {
    alert("Win");
} else if (rollResult == 2 && spinResult == 3) {
    alert("Win");
} else if (rollResult == 3 && spinResult == 1) {
    alert("Win");
} else if (rollResult == 3 && spinResult == 3) {
    alert("Win");
} else if (rollResult == 3 && spinResult == 6) {
    alert("Win");
} else if (rollResult == 4 && spinResult == 1) {
    alert("Win");
} else if (rollResult == 4 && spinResult == 3) {
    alert("Win");
} else if (rollResult == 4 && spinResult == 6) {
    alert("Win");
} else if (rollResult == 4 && spinResult == 8) {
    alert("Win");
}
*/

var fadeEffect=function(){
    return{
        init:function(id, flag, target){
            this.elem = document.getElementById(id);
            clearInterval(this.elem.si);
            this.target = target ? target : flag ? 100 : 0;
            this.flag = flag || -1;
            this.alpha = this.elem.style.opacity ? parseFloat(this.elem.style.opacity) * 100 : 0;
            this.elem.si = setInterval(function(){fadeEffect.tween()}, 20);
        },
        tween:function(){
            if(this.alpha == this.target){
                clearInterval(this.elem.si);
            }else{
                var value = Math.round(this.alpha + ((this.target - this.alpha) * .05)) + (1 * this.flag);
                this.elem.style.opacity = value / 100;
                this.elem.style.filter = 'alpha(opacity=' + value + ')';
                this.alpha = value
            }
        }
    }
}();

我使用JSFiddle查看了你的源代码，我纠正了很多像“;”声明结束：

JS

    rollResult = location.search.substr(location.search.indexOf("=") + 1);
}



var stop = false;

这是你想要的吗？

编辑：

我纠正了JSFiddle，你现在可以检查一下吗？

答案 1 :(得分：1)

不应该

if (i > 10)

是

if (i < 10)

您还需要更改

setTimeout(function () { advanceSpinner(i + 1); }, 50);

到

i++;
setTimeout(function () { advanceSpinner(i); }, 50);

否则它永远不会结束。

我还建议将i更改为全局var spinCount，否则您可能会将i与其他变量混淆。

使用 demo here 查看控制台

var stop = false;
function setValue() {
rollResult = location.search.substr(location.search.indexOf("=") + 1);
}

function spin() {

var start = Math.floor(Math.random() * (10 - 1 + 1)) + 1;
advanceSpinner(start);
setTimeout(function () {
    stop = true;
}, 4000);
//setTimeout(function () {checkWin();}, 4050);
}

function advanceSpinner(i) {
  i = i || 1;
  if (!stop) {
    if(i > 10)i = 1;
        console.log("img/board new/" + i + ".png");
        document.getElementById("spinner").src = "img/board new/" + i + ".png";
        spinResult = i;
        setTimeout(function () {
            advanceSpinner(i + 1);
        }, 50);

   }


    var spinResult;
    var gameOver = false;
    var oldHTML;
    var newHTML;
    var rollResult;
    var start;

   function setValue() {

    rollResult = location.search.substr(location.search.indexOf("=") + 1);
    //document.getElementById('own').innerHTML = "You own " + rollResult + " piece(s) on the   board.";

    }
}


function checkWin() {
 /*
if (rollResult == 1 && spinResult == 1) {
 alert("Win");
} else if (rollResult == 2 && spinResult == 1) {
 alert("Win");

  alert("Win");
} else if (rollResult == 3 && spinResult == 1) {
alert("Win");
