我正在尝试WebView使用 iframe 在一个 html 中显示多个 html 文件
我在 html 文件中使用以下脚本来调整当前 html 中 iframe 的高度。
<body onload="resizeFrames()" link="#bb7722" vlink="#bb7722" alink="#bb7722" >
<script type="text/javascript">
// Firefox worked fine. Internet Explorer shows scrollbar because of frameborder
function resizeFrames() {
var all_IFrames = document.getElementsByTagName('iframe');
i = 0;
while (frame = all_IFrames.item(i++)) {
resizeFrame(frame);
}
}
function resizeFrame(f) {
f.style.height = f.contentWindow.document.body.scrollHeight + "px";
}
</script>
<iframe width="100%" scrolling="no" frameborder=0 border=0 src="b.html"></iframe>
<iframe width="100%" scrolling="no" frameborder=0 border=0 src="c.html"></iframe>
为了使 javascript 工作，我使用以下代码：
WebSettings webSettings = wb.getSettings();
webSettings.setJavaScriptEnabled(true);
我像这样加载html文件：
webView.loadUrl("file:///android_asset/a.html");
问题是调整后的 iframe 的大小有时太大而有时太小。
我在带有 android 2.2 的 Galaxy s 上对其进行了测试，所有帧都更小（最后被切断），而在其他带有 android 4.0.4 的设备中，所有帧都更大（添加空白空间）
如果我删除了webSettings.setJavaScriptEnabled(true);Galaxy s 中的问题消失了，但在第二个设备中，框架根本不会调整大小
完整的html代码：
<!DOCTYPE html>
<html>
<head>
<style>
body{
color: #aa6611;
font-size:20px;
}
.link {
font-weight: bold;
color: #bb7722;
}
</style>
</head>
<body onload="resizeFrames()" link="#bb7722" vlink="#bb7722" alink="#bb7722" >
<script type="text/javascript">
// Firefox worked fine. Internet Explorer shows scrollbar because of frameborder
function resizeFrames() {
var all_IFrames = document.getElementsByTagName('iframe');
i = 0;
while (frame = all_IFrames.item(i++)) {
resizeFrame(frame);
}
}
function resizeFrame(f) {
f.style.height = f.contentWindow.document.body.scrollHeight + "px";
}
