I am using this code to highlight text in android webview.
public void highlight(int pageNumber) {
dbManager = new DBManager(webView.getContext());
dbManager.open();
cursor = dbManager.getSelectedID(books.get(0).getmDbId());
String quotesDb = cursor.getString(cursor.getColumnIndex("_quote"));
String currnetPage = cursor.getString(cursor.getColumnIndex("_current_page"));
List<String> myList = Arrays.asList(quotesDb.split("½_½"));
webView.evaluateJavascript("function doSearch(text, backgroundColor) {\n" +
" if (window.find && window.getSelection) {\n" +
" var windowHeight = window.scrollY;\n" +
" document.designMode = 'on';\n" +
" var sel = window.getSelection();\n" +
" sel.collapse(document.body, 0);\n" +
" while (window.find(text)) {\n" +
" document.execCommand('HiliteColor', false, backgroundColor);\n" +
" sel.collapseToEnd();\n" +
" }\n" +
" document.designMode = 'off';\n" +
" window.scrollTo(0, windowHeight);\n" +
" }\n" +
"}", null);
Log.e("SAVE_QUOTE ", "LIST_SIZE ----> " + myList.size());
if (pageNumber == Integer.parseInt(currnetPage)) {
for (int j = 0; j < myList.size(); j++) {
webView.evaluateJavascript("doSearch('" + myList.get(j) + "', 'SkyBlue')", null);
// webView.findAllAsync(myList.get(j));
}
}
}
Everything works fine until I select the code with a new line (paragraph). Then I get an error and the text is not highlighted.
/chromium: [INFO:CONSOLE(1)] "Uncaught SyntaxError: Invalid or unexpected token", source: file:///data/user/0/com.mms.tts/cache/W1/index.xhtml (1)
Try using the jQuery .select() function
For example
$(#myList.get(j)).select()
Where #myList.get(j) is a valid HTML id
Note: you will need to reference the jQuery library

This is testing code, so there might be left-overs from previous tests - FYI.
When loading the website (currently I am using Chrome) it sometimes works, sometimes nothing is loaded (THIS SITE IS NOT WORKING, and then an empty page) and sometimes I get a result like: xVºùÿý?øÿý?;"> which is the only output on the screen.
In detail it shows the following:
<html><head></head><body>xVºùÿý?øÿý?;"><script>var id = 0; [...the rest of the <script> part is loaded properly...]
I just noticed that in front of these strange characters are 364 centered points (·) but I cannot actually copy them, no editor is displaying them besides the Chrome->Inspect->"Sources"-Tab.
So basically the body is broken and these characters appear, they also do not change currently.
Can someone point me into a direction to solve this on my own, so that the website is always correctly loaded or knows what the error is?
The error seems to be on the following line:
const char* r = (std::string("") + “...”).c_str();
You are creating and std::string which allocates the raw c string on the heap. You then get the c representation of the string with .c_str(). The issue is that the string is freed since you have not assigned the string to a variable of type std::string. As a result, you were accessing memory that was not yours. When its memory wasn’t yet reused, it worked, but want is was reused by another program, it failed since you got basically random bytes from memory.
You can solve the issue by adding the following:
auto my_str = std::string("") + “...”;
Because you don’t need the raw pointer.
For the server index function, it should look like:
std::string serverIndex() {
For your init web server function:
webserver.on("/", HTTP_GET, []() {
webserver.sendHeader("Connection", "close");
auto r = serverIndex();
webserver.send(200, "text/html", r.c_str());
});
Disclaimer: this code wasn’t tested as it was only written in the app.
I am trying to create an framework where I want to find whether an webelement is hidden or not before performing an action on the web element.
I have a password field which is hidden and is structured as below
<div class=hidepassword>
<input password field >
<div>
When I query the input tag with the following lines
Isvisible1 = (string)js1.ExecuteScript("return (window.getComputedStyle?window.getComputedStyle(arguments[0], null):arguments[0].currentStyle).visibility;", myCurElement);
Isvisible2 = (string)js1.ExecuteScript("return (window.getComputedStyle(arguments[0], null).getPropertyValue('display'));", myCurElement);
Isvisible3 = (bool)js1.ExecuteScript("return !(arguments[0].offsetHeight <= 1);", myCurElement);
I am getting all the values indicating it as visible.
Later , got to know that the class which the preceding div has is making the input invisible.
I tried to get the value of overflow which is made available in the .css file for the class hidepassword
But unfortunately, there are lot of css values for the class hidepassword and when I use the below javascript function, I am able to get only one of its CSS value
public string getStyle(string ClassName)
{
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
return (String)js.ExecuteScript(
"function getStyle(ClassName) {" +
"var styleSheets = window.document.styleSheets;" +
"var styleSheetsLength = styleSheets.length;" +
"for (var i = 0; i < styleSheetsLength; i++)" +
"{" +
" var classes = styleSheets[i].rules || styleSheets[i].cssRules;" +
" if (!classes)" +
" continue;" +
" var classesLength = classes.length;" +
" for (var x = 0; x < classesLength; x++)" +
" {" +
" if (classes[x].selectorText == ClassName)" +
" {" +
" var ret;" +
" if (classes[x].cssText)" +
" {" +
" ret = classes[x].cssText;" +
" }" +
" else" +
" {" +
" ret = classes[x].style.cssText;" +
" }" +
" if (ret.indexOf(classes[x].selectorText) == -1)" +
" {" +
" ret = classes[x].selectorText + ret ;" +
" }" +
" return ret;" +
" }" +
" }" +
"}" +
"}return getStyle(arguments[0]);", ClassName);
}
Is there a way to get all the css values for the particular class name and then based on the css values for the class, we can make a call whether the element is visible or not visible. ?
Thanks in advance for all your help on this.
Selenium had supply api：isDisplayed() to detect element visibility, why you want to implement it as such complex by yourself
I've inherited a BIRT .rptdesign that isn't returning any records in "preview results." There is one open script involved, as well as a fetch script that has approximately 5 more sql queries inside of it. Much of what I have tried for solutions involves breaking out these queries involved in the fetch script into their own dataSet, and then relating them to the open script (alternatively I've tried forming a joint data set, with no luck). Even after taking out a small query from the fetch script, I'm not able to generate records in result preview. I tried to upload an image of the layout, but don't have the reputation to do so...Please let me know if you need the design file to help visualize where everything is landing!
Open script:
maximoDataSet = MXReportDataSetProvider.create(this.getDataSource().getName(), this.getName());

// Add query to sqlText variable.
sqlText = "select workorder.wonum, workorder.workorderid as workorderid1, (select min(w2.workorderid) from maximo.workorder w2 where w2.istask=1 and w2.parent=workorder.wonum and w2.siteid=workorder.siteid) as workorderid, "

I am viewing the PDF in an "object" element in IE9. I am using itextsharp to prefill a pdf template on the server, inject some app level javascript (post message and on message stuff) and then serve that up to the browser via a filestreamresult. I am using Reader 10 to view the PDF in IE9.
What works:
So far, everything works except for the PDF posting a message to the browser. I can post a message to the PDF, from the browser, no problem and all of the fields are prefilled as desired.
What doesn't work:
When I try using this.hostContainer.postMessage(["something","somethingmore"]) I get an Acrobat Escript window that says "hostContainer is not defined". I have also tried using "event.target.hostContainer" but I get "event.target is not defined". I am at a loss of what to do and any insight would be super helpful.

Stackoverflow How-To on this topic
Original guide I used
The code:
My form view:
<object id="pdfFrame" style="width:100%;height: 100%;" data="#Url.Action("LoadForm")">No luck :(</object>
My custom javascript string method:
private static string GetCustomJavascript(string existingJavaScript)
{
const string newJs =
"this.disclosed = true; " +
"if (this.external && this.hostContainer) { " +
"function onMessageFunc( stringArray ) { " +
// "var name = this.myDoc.getField(personal.name); " +
// "var login = this.myDoc.getField(personal.loginname); " +
"try{" +
"app.alert(doc.xfa);" +
"console.println('Doc xfa value = ' + doc.xfa);" +
// "event.target.hostContainer.postMessage(['hello from pdf!']);" +
// "this.hostContainer.postMessage(['hello from pdf!']);"+
// "name.value = stringArray[0]; " +
// "login.value = stringArray[1]; " +
"} catch(e){ onErrorFunc(e); } " +
"} " +
"function onErrorFunc( e ) { " +
"console.show(); " +
"console.println(e.toString()); " +
"} " +
"try {" +
"if(!this.hostContainer.messageHandler) { " +
"this.hostContainer.messageHandler = new Object(); " +
"this.hostContainer.messageHandler.myDoc = this; " +
"this.hostContainer.messageHandler.onMessage = onMessageFunc; " +
"this.hostContainer.messageHandler.onError = onErrorFunc; " +
"this.hostContainer.messageHandler.onDisclose = function(){ return true; }; " +
"}" +
"} catch(e){onErrorFunc(e);}" +
"}";
var jsToReturn = existingJavaScript + newJs;
return jsToReturn;
}
My method for filling and sending the form to the browser:
public MemoryStream GetFilledRequestForm(string fileDirectory, User user, FormView formView)
{
var pdfStream = new MemoryStream();
var templateFilePath = GetRequestTypeTemplateFilePath(fileDirectory, _requestModule.FormTemplateFileName);
var pdfReader = new PdfReader(templateFilePath);
// pdfReader.RemoveUsageRights();
var stamper = new PdfStamper(pdfReader, pdfStream);
var formFields = GetFormFields(user, formView, pdfReader);
foreach (var field in formFields.Where(f => f.Value != null))
{
stamper.AcroFields.SetField(field.Name, field.Value);
}
stamper.FormFlattening = false;
var newJs = GetCustomJavascript(stamper.Reader.JavaScript);
stamper.AddJavaScript("newJs", newJs);
stamper.Close();
byte[] byteInfo = pdfStream.ToArray();
var outputStream = new MemoryStream();
outputStream.Write(byteInfo, 0, byteInfo.Length);
outputStream.Position = 0;
return outputStream;
}
Ok, so I have resolved it, with some help of course. I found the key at this stack overflow post. I needed to wait for the object to load before assigning the message handler. Additionally, I needed a global variable in the pdf javascript to be able to post the message.
Html/Javascript: (the key here is the loadListener() function)
#model WebModel.FormView
<object id="pdfFrame" style="width:100%;height: 100%;" data="#Url.Action("LoadForm")">No luck :(</object>
<input id="buttonPost" type="button" value="post to pdf"/>
<script type="text/javascript">
var PDFObject = document.getElementById("pdfFrame");
function loadListener() {
if (typeof PDFObject.readyState === 'undefined') { // ready state only works for IE, which is good because we only need to do this for IE because IE sucks in the first place
debugger;
PDFObject.messageHandler = { onMessage: messageFunc };
return;
}
if (PDFObject.readyState == 4) {
debugger;
PDFObject.messageHandler = { onMessage: messageFunc };
} else {
setTimeout(loadListener, 500);
}
}
function messageFunc(data) {
debugger;
var messagedata = data;
alert('finally!!');
}
function sendToPdf() {
if(PDFObject!= null){
PDFObject.postMessage(
["a", "b"]);
}
}
$('#pdfFrame').ready(function() {
loadListener();
$('#buttonPost').on('click', function() {
sendToPdf();
});
});
</script>
My new function to create the javascript: (the key here is var appHostContainer)
private static string GetCustomJavascript(string existingJavaScript)
{
const string newJs =
"this.disclosed = true; " +
"var appHostContainer = this.hostContainer;" +
"if (this.external && this.hostContainer) { " +
"function onMessageFunc( stringArray ) { " +
// "var name = this.myDoc.getField(personal.name); " +
// "var login = this.myDoc.getField(personal.loginname); " +
"try{" +
"app.alert(stringArray);" +
"appHostContainer.postMessage(['hello from pdf!']);" +
// "name.value = stringArray[0]; " +
// "login.value = stringArray[1]; " +
"} catch(e){ onErrorFunc(e); } " +
"} " +
"function onErrorFunc( e ) { " +
"console.show(); " +
"console.println(e.toString()); " +
"} " +
"try {" +
"if(!this.hostContainer.messageHandler) { " +
"this.hostContainer.messageHandler = new Object(); " +
"this.hostContainer.messageHandler.myDoc = this; " +
"this.hostContainer.messageHandler.onMessage = onMessageFunc; " +
"this.hostContainer.messageHandler.onError = onErrorFunc; " +
"this.hostContainer.messageHandler.onDisclose = function(){ return true; }; " +
"}" +
"} catch(e){onErrorFunc(e);}" +
"}";
var jsToReturn = existingJavaScript + newJs;
return jsToReturn;
}
How can I, on the OnChange event, update data in my database ?
I have a WebMethod, that returns a HTML, so I can't see those elements, so I think he solution will be a javascript function.
A textarea catch the text from the database, if the user alter this, the database field has to be updated.
[WebMethod]
public static object ListAdvertise(string transaction)
{
StringBuilder retorno = new StringBuilder(160000);
Utilidade.QuebraToken tk2 = new Utilidade.QuebraToken();
string Credenciada = tk2.CarregaToken(1, HttpContext.Current.Request.Cookies["token"].Value);
string select3 = "SELECT * FROM San_Imovel WHERE Status_Id = 1 AND Credenciada_Id = " + Credenciada + " AND Transacao_Id IN (" + transacao + ") ORDER BY NomeCidade, NomeBairro, Imovel_Id ASC";
Utilidade.Conexao c3 = new Utilidade.Conexao();
SqlConnection con3 = new SqlConnection(c3.Con);
SqlCommand cmd3 = new SqlCommand(select3, con3);
con3.Open();
SqlDataReader r3 = cmd3.ExecuteReader();
while (r3.Read())
{
Imovel_Id = r3["Imovel_Id"].ToString();
Endereco = r3["Descricao"].ToString() + " " + r3["Logradouro"].ToString() + " " + r3["Numero"].ToString() + "/" + r3["DscComplemento"].ToString() + " " + r3["Complemento"].ToString() + " - " + r3["NomeBairro"].ToString();
TextoAnuncio = r3["TextoAnuncio"].ToString();

classe = "EstiloDalinhaGrid";
}
else

}
retorno.Append("<tr class='" + classe + "'>");
retorno.Append("<td>");
retorno.Append(Imovel_Id);

i think you have to use Ajax for you to be able to update your data base .
