### 使用Native.js实现打开页面默认弹出软键盘
~~~
var nativeWebview, imm, InputMethodManager;
var initNativeObjects = function() {
if (mui.os.android) {
var main = plus.android.runtimeMainActivity();
var Context = plus.android.importClass("android.content.Context");
InputMethodManager = plus.android.importClass("android.view.inputmethod.InputMethodManager");
imm = main.getSystemService(Context.INPUT_METHOD_SERVICE);
} else {
nativeWebview = plus.webview.currentWebview().nativeInstanceObject();
}
};
var showSoftInput = function() {
var nativeWebview = plus.webview.currentWebview().nativeInstanceObject();
if (mui.os.android) {
//强制当前webview获得焦点
plus.android.importClass(nativeWebview);
nativeWebview.requestFocus();
imm.toggleSoftInput(0, InputMethodManager.SHOW_FORCED);
} else {
nativeWebview.plusCallMethod({
"setKeyboardDisplayRequiresUserAction": false
});
}
setTimeout(function() {
//此处可写具体逻辑设置获取焦点的input
var input = mui("#myinput")[0];
input.focus();
}, 200);
};
mui.plusReady(function() {
initNativeObjects();
showSoftInput();
});
