我试图用iframe做点什么,而且此刻正在努力。基本上,我有一个脚本生成一个正方形网格(下图),我想这样做,以便当我点击一个正方形时,我会在不同的iframe中显示一些内容。
例如,假设我有第1帧(包含网格)和第2帧(这是"显示"帧)。如果我点击左上角的方块,那么我想显示" index(0,0)"在显示框架中。如果我点击(1,1)方格,那么我想显示" index(1,1)"等等。
我已经知道如何在同一帧内执行此操作(即如果我单击第1帧中的方块,我可以在第1帧中显示" index(0,0)")但我是只是混淆了如何在一个单独的框架中这样做。我已经尝试过很多东西,但似乎没有任何工作。
我将在下面提供我的所有代码以及一张图片供您参考。非常感谢任何帮助!
使用Javascript:
// I know this isnt good coding practice, but I was getting desperate
// trying things xD
var currentDisplay = "display";
function changeSquare() {
var image = document.getElementById(this.id);
// If image is currently green square, change to red, and vice versa
if (image.src.match("http://www.clker.com/cliparts/b/d/4/F/W/N/green-square-button-md.png")) {
image.src = "http://www.clker.com/cliparts/1/J/s/o/7/y/red-square-button-md.png";
} else {
image.src = "http://www.clker.com/cliparts/b/d/4/F/W/N/green-square-button-md.png";
}
currentDisplay = this.id;
};
function printInfo() {
document.write(currentDisplay);
}
// Creates a grid of dimensions width by height
function makeGrid(height, width) {
// Loop over height and width to create black square objects with
// buttons in middle
for (i = 0; i < height; i++) {
for (j = 0; j < width; j++) {
// Outer div is black square
var div = document.createElement("div");
div.className = "square";
div.id = ("div").concat(i,",", j);
var innerDiv0 = document.createElement("div");
innerDiv0.className = "content";
div.id = ("innerDiv0").concat(i,",", j);
div.appendChild(innerDiv0);
// InnerDiv1 & 2 are table structures (necessary for alignment)
var innerDiv1 = document.createElement("div");
innerDiv1.className = "table";
div.id = ("innerDiv1").concat(i,",", j);
innerDiv0.appendChild(innerDiv1);
var innerDiv2 = document.createElement("div");
innerDiv2.className = "table-cell";
div.id = ("innerDiv2").concat(i,",", j);
innerDiv1.appendChild(innerDiv2);
// Add green square image
var image = document.createElement("img");
image.id = ("image").concat(i,",", j);
image.src = "http://www.clker.com/cliparts/b/d/4/F/W/N/green-square-button-md.png";
image.className = "rs";
innerDiv2.appendChild(image);
document.body.appendChild(div);
// Add onclick feature
image.onclick = changeSquare;
}
}
};

答案 0 :(得分:0)
在你的changeSquare方法中,尝试这样的事情:
var frame2 = $('#frame2', top.document) //Give you top level frame jQuery Object.
为了获得更多向后兼容性,您可以使用以下内容:
window.parent.$('#frame2')
或类似的东西没有jQuery:
window.parent.getElementById('#frame2')[attributeName]
一旦拥有了根iFrame对象,就可以继续进行常规的jQuery / DOM操作。
编辑 :这是一个完全运行且经过测试的解决方案(Safari / Mac OS)。下面仅突出显示更改:
displayPanel.html:
<head>
<link rel="stylesheet" type="text/css" href="GridTest.css">
</head>
<body>
<script src="GridTest.js">
</script>
<script>
printInfo();
</script>
<div id="label1"></div> <!--Added a div for displaying text -->
</body>
GridTest.js:
function changeSquare() {
var image = document.getElementById(this.id);
//First get a reference to the second frame document
var secondFrameDocument = window.top.document.getElementById('frame2').contentWindow.document;
//Now set the value of the Div
secondFrameDocument.getElementById('label1').textContent=this.id;
// If image is currently green square, change to red, and vice versa
if (image.src.match("http://www.clker.com/cliparts/b/d/4/F/W/N/green-square-button-md.png")) {
image.src = "http://www.clker.com/cliparts/1/J/s/o/7/y/red-square-button-md.png";
} else {
image.src = "http://www.clker.com/cliparts/b/d/4/F/W/N/green-square-button-md.png";
}
currentDisplay = this.id;
};
根据您的具体情况,您可能会遇到安全问题,尤其是Chrome。更好的解决方案是使用两个Div而不是iFrame。 这是截图:
