RobotiumWeb.js就是此功能实现用的JS脚本。以solo中getWebElements()为例，
public ArrayList<WebElement> getWebElements(boolean onlySufficientlyVisible){
boolean javaScriptWasExecuted = executeJavaScriptFunction("allWebElements();");
return getWebElements(javaScriptWasExecuted, onlySufficientlyVisible);
} private boolean executeJavaScriptFunction(final String function){
final WebView webView = viewFetcher.getFreshestView(viewFetcher.getCurrentViews(WebView.class, true));
if(webView == null){
return false;
}
//做一些JS注入运行前的准备工作。比如将WebView设为可同意运行JS等，并将RobotiumWeb.js中的脚本以String形式返回
final String javaScript = prepareForStartOfJavascriptExecution();
activityUtils.getCurrentActivity(false).runOnUiThread(new Runnable() {
public void run() {
if(webView != null){
webView.loadUrl("javascript:" + javaScript + function);
}
}
});
return true;
}javascript:
function allWebElements() {
for (var key in document.all){
try{
promptElement(document.all[key]); //调用promptElement（element）函数
}catch(ignored){}
}
finished(); //运行完后，调用finished（）函数
}
function promptElement(element) {
var id = element.id;
var text = element.innerText;
if(text.trim().length == 0){
text = element.value;
}
var name = element.getAttribute(‘name‘);
var className = element.className;
var tagName = element.tagName;
var attributes = "";
var htmlAttributes = element.attributes;
for (var i = 0, htmlAttribute; htmlAttribute = htmlAttributes[i]; i++){
attributes += htmlAttribute.name + "::" + htmlAttribute.value;
if (i + 1 < htmlAttributes.length) {
attributes += "#$";
}
}
var rect = element.getBoundingClientRect();
if(rect.width > 0 && rect.height > 0 && rect.left >= 0 && rect.top >= 0){
prompt(id + ‘;,‘ + text + ‘;,‘ + name + ";," + className + ";," + tagName + ";," + rect.left + ‘;,‘ + rect.top + ‘;,‘ + rect.width + ‘;,‘ + rect.height + ‘;,‘ + attributes); //弹出包括id、text、name等字段的提示框
}
}
function finished(){
prompt(‘robotium-finished‘); //弹出包括robotium-finished字符串的提示框，用于标识脚本注入运行结束
}onJsPrompt(WebView?view,?String?url,?String?message,?String?defaultValue,?JsPromptResult?result) |
@Override
public boolean onJsPrompt(WebView view, String url, String message, String defaultValue, JsPromptResult r) {
if(message != null && (message.contains(";,") || message.contains("robotium-finished"))){
//假设提示框中包括robotium-finished字符串，即表示那段JS注入脚本运行完毕了
if(message.equals("robotium-finished")){
webElementCreator.setFinished(true);
}
else{
webElementCreator.createWebElementAndAddInList(message, view);//有人提示框中的内容。那么就能够对提示框中的内容进行处理了
}
r.confirm();
return true;
}
else {
if(originalWebChromeClient != null) {
return originalWebChromeClient.onJsPrompt(view, url, message, defaultValue, r);
}
return true;
}
}将JavaScriptEnabled设置为true。将将WebChromeClient设置为robotiumWebClient

}
});
}
