JavaScript - Need Help To Access Gridview Cell Content
Hi,
I am new to javascript and need help to get the value from af gridview cell and write it to an asp.net control on my aspx page ( language Visual Basic ). I have a gridview ( gridview1) which contains some numbers in the first column. I need to get the number in the column on mouseover and write to an asp.net label, textbox or hiddenfield. I know how to activate the script from from my aspx page, but I havent got a clue on how to write the script. Any help is deeply appreciated. Similar TutorialsI was wondering if anyone could help me with getting this working. I'm using html to create a table which has at least 1 row but no max number of rows - as they can be added/removed by the user - and 4 columns, 1st contains a checkbox and the last 2 contain drop down menus. I wish to be able to store the values of those menus in an array only if that row's checkbox has been checked. e.g if the first row has 1 and A as it's dropdown values and the second row has 2 and B. If only row 1 has been checked the array should only contain [1,A]. Instead mine holds all the values including the non-checked ones i.e [1,A,2,B]. My code for javascript function and html table are below: Code: function calculate(textID){
var table = document.getElementById('course'); //id of table
var rowCount = table.rows.length;
var array = []; //array to hold the values
var c = 0;
dmenus = document.getElementByTagName("select"); //get the drop down menus
for(var a = 1; a < rowCount; i++){ //a = 1 as the 1st row contains column headings
var row = table.rows[a];
var check = row.cells[0].childNodes[0];
if(null != check && true == check.checked){
for(var b = 0; b < dmenus.length; b++){
val = dmenus[b].options[dmenus[b].selectedIndex].value;
array[c] = val; //set index of array to equal value of dropdown box
c++;
}
}else{
b++;
}
}
Html code for table: Code: <table id="course">
<tr>
<td><input type="checkbox" name="ucheck" id="ucheck" onclick="checkAll('course')"/></td>
<th style="color:white">Course Title</th>
<th style="color:white">Credits</th>
<th style="color:white">Grade</th>
</tr>
<tr>
<td><input type="checkbox" name="tick" id="tick"/></td>
<td><input type="text"/></td>
<td>
<select name="credits" id="credits">
<option...</select></td>
<td>
<select name="grade" id="grade">
<option...</td>
It works only for the first row but if there are more than 1 row it doesn't do what it's supposed to. The coding platform I'm working on does not seem to support jquery so javascript code will be most appreciated. Thanks I'm trying to write a little Greasemonkey script (in Firefox) to manipulate the top bar Google Translate produces when translating a site. For example: http://translate.google.com/translat.../www.google.de. Google has employed traditional HTML frames. According to many websites, I can use something like window.frames[0].contentDocument to access the first frame. However, this is refusing to work! I have been debugging this for hours. I have verified that I am indeed running the script from the top-level window (window.parent === window.top), and I am able to manipulate the frames themselves without a problem. When I try something like window.frames[0].contentDocument.URL, it returns as about:blank (I also get this with the other frame, i.e., frames[1]). I have tried several different methods of getting at that frame, including getElementsByTagName("frame")[0] (which works for manipulating the frame itself, but not for editing the frame's content through contentDocument). Here's my little script so far. I've included the first part so you can see for yourself that I'm definitely in the top-level window and using the right @include because it works. In this example, the URL returned is "about:blank" (again, I'm in Firefox). Code: // ==UserScript==
// @name GTranslate
// @include /^https?://translate\.google\.com/translate\?.*/
// ==/UserScript==
// change how the frame is displayed
var bar = document.getElementsByTagName("frame")[0];
bar.removeAttribute("noresize");
// manipulate the content inside the frame
var gt = bar.contentDocument;
alert(bar.URL);
Hello, I am trying to move each cell content from one table to another table. I do not want to lose the value of each cells in table1, but just to show how I got table2 from table1. I would like to show/animate the movement. So when the user clicks the button the data from table1 will scroll towards table2. I am new to HTML/javascript programming I really appreciate your help Hi friends i have a gridview with id gvcustomers...it has tow columns latitudes and longitudes i want to loop thoiugh the gridview on the client side and get the values like this...but the problem i have is mentioned in the comments below var theGridView = document.getElementById('<%=gvCustomers.ClientID%>'); for (var rowCount = 1; rowCount < theGridView.rows.length; rowCount++) { /// the numbers in the array are lats and longs which are hard //coded...this where i want the latitude and longitude colmn to come.. var latlongs = new Array(new VELatLong(45, -110), new VELatLong(45, -114), new VELatLong(45, -90), new VELatLong(45, -95)); // } How can i achieve this...thank you akpaga Senior Apprentice Senior Apprentice LTD Bronze - Rating: 3 Posts: 167 Joined: Wed May 27, 2009 4:15 pm Unrated Hi all, Does anybody know how to get the rownumber from a gridview on mouseover. The gridview is on an aspx page and i need to call the javascript from the rowcreated part. I am still a newbie to javascript, so any help is a lot of help. Thank you hi guys i hava gridview gvcustomers with following fields latitude,longitude,customer and i have a javascript function in my aspx page fucntion Customer() { AddCustomer(lat1,long1)--- row1 of gridview lat long AddCustomer(lat2,long2)--row2 of gridview lat long } in the above function i would like to loop through the gridview and get the latitude and longitude colmns in the function instead of hardcoding as i have been doing now...thank you i advance I want to change the color of the gridview when a button which has the value of the row index of the gridview is clicked ...this button is not inside the gridview but some where else on the form but it can send the gridview rowindex to the function so need a function to change the color of the row or bring it to focus in someway... <script language="JavaScript"> function changeColor(cell_id){var state1="#dde6ed"; var state2="#ffc20e"; var cellid = new Array ("id1", "id2", "id3", "id4", "id5", "id6"); for(var i = 0; i < cellid.length; i++){var nav = document.getElementById(cellid[i]); if(cellid == nav.id){nav.style.backgroundColor=state2;} else {nav.style.backgroundColor=state1;}}} </script> Can anyone tell me what is wrong with this script. I put an onClick= changeColor(this);" in my <td> tag to call the script but still not working. Hi all, I am using xmlhttp.open();xmlhttp.send(); to send a php content to a div. This php content is again using the same method to get php content from a further page. The content of the div, does not seem to be using the css and javascript files defined in the calling pages <head> section. Does anyone know why this is? Is there a workaround or solution to this problem?

Sup gents. Excuse my tenaciously novice questions, but dont disparage just yet, im beginning to grasp how the mechanism behind the code words, in due part to your helpful suggestions Im in the last stages of the code. In this section i have added three methods, whose function is to direct access control over the ciphers i will be adding shortly. I firstly need for the methods to be working. What they do is, categorize the set of values inside the first array and give a set of names privileges. The three methods that deal with the access control are link(), secondgroup() and third group. Ive assigned that the first three names( link() ) can access all the ciphers, ie administrators, the next three names ( secondgroup() ) can only access the shift, permutation and vigenere ciphers and the rest ( thirdgroup() ) can access the other remaining ciphers. But ive added so much code at once that i overwhelmed myself and i now i cant figure out where ive gone wrong, be it in the syntax or the logic Code: <html>

it is said that the 'form' node can be accessed by document.forms.certainName but it fails on my browser(IE8) however for images, it works, that is, document.images.certainName returns a Node. is there bugs only on 'form' tag? btw, document.forms[0] works ... quite quirky... i noticed today that if i type in my js file name in the url i get a download box, i have an htaccess on my site so this should not be happening, thats another issue.. my question is, is there a trick to creating a js file that cant be accessed in this manner, i was thinking about adding a php define statement as it comes from one source only, but i wanted to ask first to see if there was something on the js side i could do or is that strictly a htaccess or server side issue.. Hi this is what I want to do. I have an online store and a need get fixed the machines from where my clients use my web site. what I'm doing right now is using an activeX to retrieve theirs OS code, HD serial number and other stuff and is working fine but since I'm using an ActiveX they are forced to use Internet Explorer and that's the big problem. my clients agree for me doing this check on their computers, actually they allow the activex to run, but they are requesting the posibility of using for example mozilla. thanks in advance and sorry about my english I'm just learning Hi guys can help me are very little versed in javascript ... I explain my problem! I have a table where they passed the results of a query ... The table field is called Article and consists of about 500 characters, but the substring in the table with a step the first 40 characters, and now the question arises ... I would click on the text of the article and see the page the entire article ... Code: query="SELECT * FROM Articolo ORDER BY titolo DESC";
ResultSet r = stmt.executeQuery(query);
%>
<table border="1">
<tr><td> titolo </td> <td> articolo </td> <td> data inser </td></tr>
<%
while(r.next())
{
Tot = r.getString("titolo");
Art = r.getString("articolo");
dat = r.getString("data_inserimento");
String meta = "";
String metadata = "";
meta = Art.substring(0,40);
metadata = dat.substring(0, 10);
StringBuffer sb = new StringBuffer(meta);
sb.replace(37,40, "...");
String s2 = sb.toString();
%>
<tr>
<td> <%= Tot %> </td>
<td> <a href="#" onClick="this.innerText = '<%= Art %>';"><%= s2 %></a> </td>
<td> <%= metadata %> </td>

I have a table with two rows and 4 columns, the first cell has rowspan of 2. How do I insert something into the first cell only? How can I get the cell index of the first cell?
Hello, I am trying to set up this Javascript to work with my XML exported from Microsoft Access for support on an Intranet page. I borrowed from a tutorial code but I cant seem to figure out how to get the Javascript to recognize my values in the xml file. I believe my issue is related to the formatting of the xml file. The example is formatted like Code: <index> <name><![CDATA[ Paul ]]></name> <age><![CDATA[ 26 ]]></age> <height><![CDATA[ 6'0" ]]></height> </index> While my access file exports a little messy... Sadly, unless this can be changed.. I would love to just enter the code myself for each entry.. but I need it to be exportable and immediately updated to the Javascript search. Access exports like this. Code: <Employee_x0020_Database> <Employee_x0020_Number>200786</Employee_x0020_Number> <First_x0020_Name>Stacey</First_x0020_Name> <Middle_x0020_Name>Leanne</Middle_x0020_Name> <Last_x0020_Name>Evans</Last_x0020_Name> <Gender>F</Gender> <Date_x0020_of_x0020_Hire>2005-04-07T00:00:00</Date_x0020_of_x0020_Hire> <Position>Cashier</Position> </Employee_x0020_Database> Any advice on how I can get Javascript to recognize the values without a CDdata tag?

Thanks for helping me with this... Totally way over my head on this one. Delvok Hi, I'm a retired social worker with beginner skills in scripting a web page and need some suggestions. I create eLearning materials which are given away as a communty service to help people improve their health. A typical eLearning project has a few educational screens (using a Learner Management System-LMS-template) and an interactive exercise (on an external web page-htm or html-usually accessed by button which navigates to the exercise's URL). The interactive exercise should only be accessed from inside the eLearning lesson using the button, because it requires understanding of the way it works plus important cautions to assure proper use. I need to prevent the use of the URL outside of taking the lesson (for example, someone taking the lesson acquires the exercise's URL from their browser history and then may give this to others who access the exercise directly-without necessary knowledge and cautions). I tried document.referrer, using JavaScript. Using the referrer URL from inside the lesson and adding the JavaScript to the exercise's htm code worked OK in FF, but not in IE 8. In FF, if the referrer was not the correct single URL from inside the lesson, then it redirected; if the correct URL, the exercise appears. The JS code follows: Code: <script language="JavaScript" type="text/javascript">
<!--
var oksite = "http://www.mysite.com/xyz/courseidxxxxx/yyyy/zzz.html";
var redirect = "http://mysite.com/error.html";
if (document.referrer != oksite)
{
location.replace(redirect);
}
//-->
</script>
In IE 8, I was not able to get it to work. Using an alert, I noticed that the referrer in IE 8 was blank. My web hosting (GoDaddy) is a shared Windows hosting. I would have to upgrade from IIS6 to IIS7 to use PHP. Bigger challenge: I've never used PHP. If possible, I would prefer to use JS. But, I am open to any suggestion that will help. I am also wondering if part of the IE 8 issue is that I am using IE 8 X 64? I'm stuck and hope someone can suggest a way to solve this access issue. Thanks for your help. Kind Regards, saratogacoach First post! Hey all! So I've been having trouble figuring out how to make this page work. The page I'm working on has 3 frames: top/main/title frame, left frame, and right frame. What the page is supposed to be is like a shopping page. The left frame has all the items that you can select, while the right page has the "receipt" of your selected items. Now here's the problem: The left frame has an "Update Order" button on the bottom that updates the receipt on the right frame. However, I can't get the button to work. I'm not exactly sure how to write the code for the receipt frame (if there is any javascript code needed for that frame) or how to have the left frame send all that information to the right frame. I hope this all makes sense. Thanks for taking the time to read all that! Hi someone please let me know the way to access a smarty value with javascript? my smarty value is = {$value.url} i want to access it like Code: <script type="text/javascript">
function load()
{
document.location = '{$value.url}';
}
</script>
i tried with wrapping code with {literal} {/literal} but it isnt working. can some one correct this please sorry for bad english Thanks |
