JavaScript - Read File From Word Export

Hi,

i have a question, is JavaScript can read an external file? i have an ear file, can it read external file without the external file compile together in the ear file? can we do so?

Hi, i need to read a files contents to an array so that i can check which lines of the file i need to write back. im not very good with arrays and haven't had any luck so far.

thanks

for some reason I am unable to read the file contents, or it could be something else, I added in some extra code to see where the script got to and I only get to see '1' on the output.

Is there something else I have missed ?

I am wanting to ready each line one by one and replace a phrase with another, then output the new line.

I visit the 1.txt file in my browser and the file shows fine.


var txtFile = new XMLHttpRequest();
txtFile.open("GET", "http://mysite.com/convertJS/1.txt", true);
txtFile.onreadystatechange = function()
{
document.write("1<br>");
if (txtFile.readyState === 4) { // document is ready to parse.
document.write("2<br>");
if (txtFile.status === 200) { // file is found
document.write("3<br>");
allText = txtFile.responseText;
lines = txtFile.responseText.split("\n");

document.write(lines + "<br>");

// I shall be altering the text in each line, search and replace, so only need to be able to read one line at a time.

}
}
}
txtFile.send(null); // close file.


sorry that i used the quote method to post, but when i used [ code ] it corupted the text as the document . write lines?!

I am wanting to setup a dependant drop down where when a user clicks on the first drop down, it changes the contents of the second. The way I intend to do this is via a csv file. I have found several scripts but I have been unable to get them to work.

Two of which a

The first is the better option from what I can see. but the problem is readyState seems to be always 1.

I am wondering if someone could perhaps give me a few moments to see if I can get this to work or suggest a better solution.

I don't want to use a database approach, at least not yet.

I am having trouble with JavaScript code and do not know why it is not working. I have the code I think is right but it is not showing up in my browser when run. Any ideas?
Also are there any other ways to read in an xml file using javascript? please list if so.

I have around 100,000 html files that I need to do a search/replace on.

I currently have the word "Manchester" in all of these files which needs replacing with the full file path
location;

C:\Demo_Folder\Manchester_file_001.html
C:\Demo_Folder\Manchester_file_002.html

Your help would really help me sort out my mind blowing task I've been given.

Thanx in advance

can u please suggest some idea. thanks.

Sorry about the title, I didn't know what else to use to describe my problem.

Basically, I'm generating a random word with a function; then I'm trying to pass this word down to another function. The problem is, when I pass the word, it changes each time (due to it being randomly generated originally).

I'm only calling the function once (via button click), but I'm also calling the function in my code lower down to retrieve the returned variable; and the function seems to be running again and returning a new word from my array.

Here's a snippet of my code:
Code:

function ranNum(){
	var ranNum = Math.round(Math.random()*10);
		var chosenWord = wordArray[ranNum];
			return chosenWord;
}

function makeBoxes(x){
//remove children when new word is chosen
var hM = document.getElementById("hangMan");
	while(hM.firstChild){
		hM.removeChild(hM.firstChild);
	}	
	
	var chosenWord = ranNum(x);
		var wL = chosenWord.length;

		//create box for length of letters in word
		var i = 0;
		for(i=0;i<wL;i++){		
			var cBoxes = document.createElement("div");
				cBoxes.className = "letterBoxes";
					cBoxes.innerHTML = chosenWord.charAt(i);
						hangMan.appendChild(cBoxes);
				}
				
		return chosenWord;
}

function checkLetter(y){
	var chosenWord = makeBoxes(y);
		alert(chosenWord);
}

So I generate a word with one button; now I need to be able to work with said word in my checkLetter() function. The word changes however.

Any help would be greatly received.

I found a nice script online that will count words. Problem is, I need it to also count each DIGIT (0-9) as a seperate word, whether the numbers are seperated by a space or not. I've searched this forum to no avail. Can anyone help me or show me how to do this, here is the original script:

Code:

Hi,

I have a code written in Javascript to export to Excel.
It is not working for my PC as open office is installed in it.
If I check with ms-office the code works, can anyone please suggest me what shld i do for it.
Below is the code in javascript.

function exportToExcel()
{
var oExcel = new ActiveXObject("Excel.Application");
var oBook = oExcel.Workbooks.Add;
var oSheet = oBook.Worksheets(1);
for (var y=0;y<detailsTable.rows.length;y++)
// detailsTable is the table where the content to be exported is
{
for (var x=0;x<detailsTable.rows(y).cells.length;x++)
{
oSheet.Cells(y+1,x+1) =detailsTable.rows(y).cells(x).innerText;
}
}

Please suggest me what code i should keep or what I should change.
-- Thanks in Advance..

Hi Chaps,

I have some Javascript code, that sucessfully exports Project data from an HTML table to an Excel SpreadSheet:
Code:

function ExportToExcel() {		
			var xlApp = new ActiveXObject("Excel.Application");
			// Silent-mode:
			xlApp.Visible = true;
			xlApp.DisplayAlerts = false;
			var xlBook = xlApp.Workbooks.Add();
			xlBook.worksheets("Sheet1").activate;
			var XlSheet = xlBook.activeSheet;
			XlSheet.Name="Project Details";
			
			// Store the sheet header names in an array
			var rows = tbldisplay.getElementsByTagName("tr");
			var columns = tbldisplay.getElementsByTagName("th");
			var data = tbldisplay.getElementsByTagName("td");
			
			//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
			var d = 0;
			for (r=4;r<rows.length+3;r++) { // start at row 2 as we've added in headers - so also add in another row!
				for (c=1;c<columns.length+1;c++) {
					XlSheet.cells(r,c).value = data[d].innerText;
					d = d + 1;
				}
			}
			
			//autofit the columns
			XlSheet.columns.autofit;
			
			// Make visible:
			xlApp.visible = true;
			xlApp.DisplayAlerts = true;
			CollectGarbage();
			//xlApp.Quit();
}

As you can see, a new workbook is created and the data is exported to Excel ("Sheet1").
What I want to do is as soon as this export is complete, redirect to a seperate page, where the Jobs (linked to the Project) details are exported to Excel ("Sheet2"), without creating a new workbook.
Is this do-able?

I have this idea that I want to do basically a "state capture" of a web page through javascript.

Basically, a user will click a button, and the script will run, capturing all objects and their styles in a way that can be recreated later without referencing external CSS files and images.

The script could export HTML or JS, but obviously all images would have to be data urls and all styles would have to be inline/hard coded.

Does anyone know of a tool that do this or have any advice on where I would start? I'm thinking it would be very useful for a bug report submission on an application I'm working on.

Sure, the user can upload a screenshot, but I'm trying to save them the step (and basically have a screenshot on every bug report). JS cannot do an actual image capture, so I think a full dom export would be just as good.

Any ideas would be fantastic.

Hi Chaps,

I have a Javascript ActiveX function that exports the contents of an HTML table into MS Excel. The script works fine, however, some of the dates have changed from dd/mm/yyyy to mm/dd/yyyy. I do not know why this is happening, especially as it's only to a few.
Here is the code:
Code:

<script language="javascript" type="text/javascript">  
function ExportToExcel() {
	input_box=confirm("Export to Microsoft Excel?");
		if (input_box==true) {
			
			var xlApp = new ActiveXObject("Excel.Application");
			// Silent-mode:
			xlApp.Visible = true;
			xlApp.DisplayAlerts = false;
			var xlBook = xlApp.Workbooks.Add();
			xlBook.worksheets("Sheet1").activate;
			var XlSheet = xlBook.activeSheet;
			XlSheet.Name="Report";
			
			// Store the sheet header names in an array
			var rows = tblreport_work.getElementsByTagName("tr");
			var columns = tblreport_work.getElementsByTagName("th");
			var data = tblreport_work.getElementsByTagName("td");
			
  			// Set Excel Column Headers and formatting from array
			for(i=0;i<columns.length;i++){
				XlSheet.cells(1).value= "Projects - Open";
	   			XlSheet.cells(3,i+1).value= columns[i].innerText; //XlSheetHeader[i];
	   			XlSheet.cells(3,i+1).font.color="6";
	   			XlSheet.cells(3,i+1).font.bold="true";
	   			XlSheet.cells(3,i+1).interior.colorindex="37";
				XlSheet.Range("B1:F1000").HorizontalAlignment = -4108;
				XlSheet.Range("H1:H1000").HorizontalAlignment = -4108;
				XlSheet.Range("J1:J1000").HorizontalAlignment = -4108;
			}
			
			//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
			var d = 0;
			for (r=4;r<rows.length+3;r++) { // start at row 2 as we've added in headers - so also add in another row!
				for (c=1;c<columns.length+1;c++) {
					XlSheet.cells(r,c).value = data[d].innerText;
					d = d + 1;
				}
			}
			
			//autofit the columns
			XlSheet.columns.autofit;
			
			// Make visible:
			xlApp.visible = true;
			xlApp.DisplayAlerts = true;
			CollectGarbage();
			//xlApp.Quit();
		}
}
</script>

If anyone has some ideas on how to correct this, I'd be most grateful!

Hi !

I would need to select whole word (same thing as when you double click a word) just by single clicking on it, or by positioning the cursor above the word(any letter of a word). Then i would need to manipulate the selection(to change selected text to some other text).

The outcome would be an editor with a possibility to change selected word (to add diacritical marks to selected word).

I've been googling for this for long time and can't find an answer. It can be connected to range object that is not the same in IE a firefox - but i did not manage to make it work. Or is my approach wrong ?

Do you have any idea how to do this?


Thank you in advance !
