Excanvas.js 在 IE8 中不适用于我

发布于 2024-11-29 10:02:40 字数 1006 浏览 0 评论 0原文

尝试在 IE8 中实现画布效果。使用excanvas.js在IE7中没有问题，但在IE8中不起作用。该效果名为 ECOTree，我已经完成了所有技巧和所有修改，包括这里。有什么建议可以在 IE8 中运行此效果吗？

以下是ecotree.js中ie8的修改代码：

// Make the <canvas> element.
var canvas = document.createElement('canvas');
jQuery(canvas).attr('width', 2000).attr('height', 7000).attr('id', 'ECOTreecanvas').appendTo(this.treeContainer);
if ((jQuery.browser.msie) && (parseInt(jQuery.browser.version, 10)<=8)){
    // For Internet Explorer, have excanvas initialize the canvas method
    // Modification, the major versions greater than 8 don't need excanvas.
    canvas.setAttribute('width', '2000');
    canvas.setAttribute('height', '7000');
    canvas.setAttribute('id', 'ECOTreecanvas');
    this.treeContainer.append(canvas);
    if (typeof G_vmlCanvasManager != 'undefined') {
        canvas = G_vmlCanvasManager.initElement(canvas);
    }
}

Trying to make a canvas effect work in IE8. With excanvas.js there is no problem in IE7, but in IE8, it doesn't work. The effect is named ECOTree, and I have made all the tricks and all the modifications included here. Any suggestions to run this effect in IE8?

Here is the modified code for ie8 in ecotree.js:

// Make the <canvas> element.
var canvas = document.createElement('canvas');
jQuery(canvas).attr('width', 2000).attr('height', 7000).attr('id', 'ECOTreecanvas').appendTo(this.treeContainer);
if ((jQuery.browser.msie) && (parseInt(jQuery.browser.version, 10)<=8)){
    // For Internet Explorer, have excanvas initialize the canvas method
    // Modification, the major versions greater than 8 don't need excanvas.
    canvas.setAttribute('width', '2000');
    canvas.setAttribute('height', '7000');
    canvas.setAttribute('id', 'ECOTreecanvas');
    this.treeContainer.append(canvas);
    if (typeof G_vmlCanvasManager != 'undefined') {
        canvas = G_vmlCanvasManager.initElement(canvas);
    }
}

您发布的内容看起来不正确，您需要提供更多详细信息，但是我可以说您的很多代码都是多余的。

// Make the <canvas> element.
var canvas = $('<canvas id="ECOTreecanvas" width="2000" height="7000"></canvas>').appendTo($(this.treeContainer));
if (typeof G_vmlCanvasManager != 'undefined') {
    G_vmlCanvasManager.initElement(canvas);
}

我假设您仅在浏览器较旧时才包含 excanvas。

Nothing you posted looks incorrect, you will need to provide more detail, however I can say that a lot of your code is redundant.

// Make the <canvas> element.
var canvas = $('<canvas id="ECOTreecanvas" width="2000" height="7000"></canvas>').appendTo($(this.treeContainer));
if (typeof G_vmlCanvasManager != 'undefined') {
    G_vmlCanvasManager.initElement(canvas);
}

I am assuming here you only include excanvas when the browser is old.
