Android WebView 获取HTML表单内容
前言
Android获取WebView里面表单的内容之前还真没接触过，昨天Android面试有面试官问到了，那么我就总结一下吧。
代码
HTML
JavaScript获取表单的内容，console一下打印下效果。
window.JSInterface.passParams(this.value);<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/html">
<head>
<base href="<%=basePath%>">

测试Android获取HTML表单数据
<input type="text" name="testName" id="testId" />
</form>
<script type="text/javascript">
document.getElementById("testId").oninput = function() {
console.log(this.value);
window.JSInterface.passParams(this.value);
}
</script>
</body>
</html>Android
class JSInterface {
@JavascriptInterface
public void passParams(String value) {
Toast.makeText(MainActivity.this, value, Toast.LENGTH_SHORT).show();
}
} webView.addJavascriptInterface(new JSInterface(), "JSInterface");package net.cctv3.JobConclusion;

webView = findViewById(R.id.main_web);
webView.setWebViewClient(new WebViewClient() {

return false;
}
});
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.loadUrl("http://192.168.1.5:8080/Job");
webView.addJavascriptInterface(new JSInterface(), "JSInterface");
