Javascript Window.onload函数在chrome中不起作用？
我们制作了一个带有函数的脚本，我正试图用window.onload调用它。脚本的目的是在页面加载时用两个图像填充画布。这适用于Firefox、Internet Explorer和Safari，但不适用于Google Chrome。我们已经在谷歌上搜索过这个问题，但还没有找到，所以我们希望你们中的任何人都能帮助我们 这是HTML和Javascript代码：Javascript Window.onload函数在chrome中不起作用？,javascript,google-chrome,onload,Javascript,Google Chrome,Onload,我们制作了一个带有函数的脚本，我正试图用window.onload调用它。脚本的目的是在页面加载时用两个图像填充画布。这适用于Firefox、Internet Explorer和Safari，但不适用于Google Chrome。我们已经在谷歌上搜索过这个问题，但还没有找到，所以我们希望你们中的任何人都能帮助我们 这是HTML和Javascript代码： <!DOCTYPE html> <html> <head> <meta charset="U

对于（s=1；将脚本标记放在主体或头部内。并使用事件侦听器，这是公认的标准方式：window.addEventListener（'load'，time2paint，false）
。感谢您回复@somethinghere-我们刚刚添加了事件侦听器，并尝试按照Alex K的建议将脚本标记放入正文中。但是，这并不能修复在chrome中加载画布图像的问题。不，不幸的是@somethinghere无法正常工作。您的控制台怎么说？它一定报告了一个错误。
