JavaScript - Collect Data From Html Using Javascript?
Hi guys
I d like to know that is it possible to submit data to the server or to an email from the client using JAVAScript? I know that javascript is clientside,but if you work with Facebook, when you chat, just view its source, u ll see that is using Javascript? I d like to know,how is it possible? Similar TutorialsI am trying to write a report-generator to collect user-comments from a list of external HTML files. User-comments are wrapped in < span> elements. Can this be done using JavaScript? The files are all available locally and I am using file:// protocol for the access. Here's my attempt: Code: function generateCommentReport()
{
var files = document.querySelectorAll('td a'); //Files to scan are links in an HTML table
var outputWindow = window.open(); //Output browser window for report
for(var i = 0; i<files.length; i++){
//Open each file in a browser window
win = window.open();
win.location.href = files[i].href;
//Scan opened window for 'comment's
comments = win.document.querySelectorAll('.comment');
for(var j=0;j<comments.length;j++){
//Add to output report
outputWindow.document.write(comment[i].innerHTML);
}
}
}
Hello folks! This is my first time posting here, and I am relatively new to JavaScript. I have come in need of assistance in guiding me in the right direction. My intentions are to create a web-based page where one can select from a few drop down menu's, and enter a few select pieces of information. This information would then be logged for later purposes, when the user chooses to retrieve this information (during the initial usage, no long term storage) in the format of a report. Would anyone have sources to similar coded applications, or any ideas of the directions I can go in for further assistance. I have at this point been utilizing the W3 website to learn. Thanks a ton! Hi, I am new to javascript, Please help me with the issue below. My javascript code below should actually fetch the data from html table on button click. function displaymessage() { alert ("button pressed"); var table_cells = new Array(); var table7 = document.getElementById('Auth'); for (i=0,n=table7.rows.length; i < n ; i++) { var Rowdata = table7.rows[i]; table_cells[i] = new Array(); for(j=0,cols = Rowdata.cells.length; j < cols; j++) { table_cells[i,j] = Rowdata.cells[j].innerHTML; alert (table_cells[i,j]); } } alert (table_cells[1,1]); alert (table_cells[2,1]); alert (table_cells[3,1]); alert (table_cells[4,1]); alert (table_cells[5,1]); alert (table_cells[6,1]); alert (table_cells[7,1]); alert (table_cells[8,1]); } The problem with my code above is that the statement "alert (table_cells[i,j]);" executes properly and shows the correct value. But the other alert statements shows only the value of the last row of the table. i.e., my table has 9 rows. and all the alert statements shows 9th row's 2nd column's value outside the for loop. But inside the for loop it executes fine. I tried it in IE7. I seem to miss something. Could someone please help me out with this? Thanks in advance. Hello, I am trying to get all the div tags in my page into an array but only the tags with the ID "image**". Below is what I came up with but this doesn't seem to work, even after googling a bit I couldn't find any solution. I don't think this should be so hard but I'm very new to JavaScript (tbh programming in general) and can't seem to come up with a solution. Any help or pointers would be greatly appreciated. Code: function divs() {
var divs = document.getElementsByTagName('div');
var ImageTags = [];
for (i=0; document.getElementsByTagName('div').length; i++) {
var div = divs[i];
if (/image[0-9]*/.test(div)) {
imageTags.push(div);
}
}
}
Hello, I'm a newbie... Have a teensy bit of Javascript skills from school. I have two questions about a popup window I've installed on my website to collect subscriptions. The code below is working on my website here http://ruthysrides.com.au/cycling-accessories.php, and is programmed to appear once per user every 30 days. Questions a 1. I want to know how I can make the popup open centred on the screen. (I've looked at a few examples of code but can't see where to insert the instruction) 2. Ideally I want to insert the popup on every page and set it to appear after the user has been browsing for 60 seconds, but I couldn't get example codes working so settled for this one. I initially installed it on 3 different pages, but it only recognised the cookie from one page and so when the user clicks on another page with the script installed, the subscription prompt pops up again. Annoying for customers, so I've only got the script running on the one page at the moment. <script language="javascript"> var expDays = 30; // number of days the cookie should last var page = "http://www.ruthysrides.com.au/subscribe.php"; var windowprops = "width=340,height=300,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=yes"; function GetCookie (name) { var arg = name + "="; var alen = arg.length; var clen = document.cookie.length; var i = 0; while (i < clen) { var j = i + alen; if (document.cookie.substring(i, j) == arg) return getCookieVal (j); i = document.cookie.indexOf(" ", i) + 1; if (i == 0) break; } return null; } function SetCookie (name, value) { var argv = SetCookie.arguments; var argc = SetCookie.arguments.length; var expires = (argc > 2) ? argv[2] : null; var path = (argc > 3) ? argv[3] : null; var domain = (argc > 4) ? argv[4] : null; var secure = (argc > 5) ? argv[5] : false; document.cookie = name + "=" + escape (value) + ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + ((path == null) ? "" : ("; path=" + path)) + ((domain == null) ? "" : ("; domain=" + domain)) + ((secure == true) ? "; secure" : ""); } function DeleteCookie (name) { var exp = new Date(); exp.setTime (exp.getTime() - 1); var cval = GetCookie (name); document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString(); } var exp = new Date(); exp.setTime(exp.getTime() + (expDays*24*60*60*1000)); function amt(){ var count = GetCookie('count') if(count == null) { SetCookie('count','1') return 1 } else { var newcount = parseInt(count) + 1; DeleteCookie('count') SetCookie('count',newcount,exp) return count } } function getCookieVal(offset) { var endstr = document.cookie.indexOf (";", offset); if (endstr == -1) endstr = document.cookie.length; return unescape(document.cookie.substring(offset, endstr)); } function checkCount() { var count = GetCookie('count'); if (count == null) { count=1; SetCookie('count', count, exp); window.open(page, "", windowprops); } else { count++; SetCookie('count', count, exp); } } window.onload=checkCount; </script> Help anyone? Big thank you in advance!!! Hi, I am new to indesign javascript. I need to collect all the style information from an indesign file and i have to display as combo box and the user should seelct the style name. The selected style names i have to list in a seperate text box and when i select okay i have to search some text and replace in the document where this selected style name paragraphs only. This is my requirement. Can anybody help me to do this? Thanks in advance Anil favorite I'd like to modify a form on www.formsite.com (form builder app): username: testuser password: password I would like to use the nicedit.com's inline content editor's js to transform my textarea's into a richtext area. At present the nicedit editor works well in creating the richtextarea. However, the KEY point is that I would like formsite's form to pipe in the the created html and render it with the html component of formsite. Currently, the pipe function in formsite will only put out the html syntax in it's html module. action seen he http://fs8.formsite.com/testform/form1/index.html So this would be: 1. checking out my form on formsite.com 2. the script from nicedit.com is already installed in an html component. 3. changing or telling me the scripts/tags/or whatever for formsite form using formsites form builder (which allows some html/script editing). 4. changed so as to render the rich text entered on page 1 in page 2 instead of the html syntax. Any other solutions using formsite and any other richtextarea solutions would be great too!

Thanks Hello, I used a standard orderform which I expanded. With this form people can order some products. But when I submit the form with data from a javascript the mail is empty. Can anyone help? I am just a beginner.... You can try the form here Thanks in advance!

For some reason i dont know why the javascript isnt reading the function even tho they are correctly named, the file is being read as the 1st test alert comes up. the 2nd one inside the function doesnt know. can anyone point in the right place or show me where i am going wrong. as you can see i have put both my entire form and and the java file up. so you can easily see what goes on #on a note i have multiple forms in a tab system if that has anything to do with it although i shouldnt see why it should. #oh and did i get my regex correct for ck_price e.g "9.99 or 10.99" and ck_abv eg "4.2 or 10.2 or 34" #im also using wampserver 2.1 with win7 and chrome if it's needed thanks ste Please help ... bit urgent I am creating a small automated system where front-end is html query form and back-end database is MS excel. both at local PC only & in a single folder. problem is like a survey form. continuous data entry, error correction, read/wite all these are included. I created a program upto first entry; but the second, third, ... entries and it is continuous. pl help me regards K.Kaniraj I have some data on the client side in javascript arrays that I display to user in a html table on the webpage. I want to give an option to the user to save the data in excel. I thought of a solution that involves: 1. Create an http request and post the data as json 2. On server using jsp convert the json data to html table 3. Set the response headers to open the response in excel This solution works, but does not look optimal. Why to send a http request to server when all the data is there on client side. I tried creating a new document on the client side and open that in a new window. That does not open the document in excel as the response header is not set. Any suggestions on how to achieve this. I want to avoid http request to server. Thanks, Pawinder I cannot figure out how to total my column data correctly with JavaScript. The code I have will enter a new row, but it is not summing the columns. The new row is just filled with zeros. Code: function totalColumns() {
var tds = document.getElementById('users_table').getElementsByTagName('td');
var sum = 0;
for(var i = 0; i < tds.length; i ++) {
if(tds[i].className == 'dataRow') {
sum += isNaN(tds[i].innerHTML) ? 0 : parseInt(tds[i].innerHTML);
}
}
document.getElementById('users_table').innerHTML += '<tr><td>' + sum + '</td><td>' +sum+ '</td><td>' +sum + '</td></tr>';
alert ("Columns have been totalled and listed at the bottom of each");
} //end totalColumns
I can't figure out how to get the rows to total at all. Any insight would be appreciated! Thanks! I wants to access server web page which data is continuously growing(streaming data), I want to buffered some of that data write it in responseText then again get next buffered data write it and so on (in AJAX). Is it possible? if yes how to do that? What i am trying to do is to make a system on my website that will grab Data from one or two different divs on one page and have it post it in an alert box on the homepage. http://killerz297.webs.com/events.html on that page i would like to be able to have javascript automatically grab the text from the description and paste it into the red box on this page: http://killerz297.webs.com/index.html what i have so far is on this page in the red box i have a script that countsdown how long until the event is away from the set time i put in it until the event starts at a set time it shows the event description, and then while the event is going on it says event in session, then after the event is over it says event no longer ongoing. but then i have to edit the script to the next event. I would like javascript, or what ever type of code it would take to do this to automatically grab the information. I would like for it to automatically switch the information to the next line when the current event is over and start a countdown from there. This is a lot of coding to do but i just am not THAT familiar with how to write javascript to do this myself. One other thing i would likkeeeee is for the red box on home page to disappear until it is 24 hours until next event, and then automatically close 1 hour after event gets over. Not a big deal if i can't get this but i would love it if someone could. okay finally, that is about it lol. If someone could help me with this i would appreciate it soo soo much! Thanks, hope someone could help me. It will be best to use server side scripting like php for it , because user can disable his javascript in that condition your code won't work
