JavaScript - Trigger Event In Popup From Main Page
First, I will state that I am totally inexperienced in JavaScript.
I have a web site application written in VB.net and asp. The main page uses JavaScript to load a popup page that performs multiple tasks. The main page accepts a variety of incoming messages, only SOME of which need to be passed to this popup page for processing. I found an ugly way to pass the message to the popup by placing it in a Session variable. Now I need to cause it to be handled. I see two possibilities, and I do not have a clue how to implement either. Either one would be great: 1. In the main page, trigger a subroutine in the popup, using JavaScript. OR 2. In the popup, establish a trigger any time that Session variable changes. Thanks in advance for any help on this. Similar TutorialsHello, I have this onchange event that occurs after user selection of a dropdown menu. When a user makes a selection it queries the database and delivers some data. The value of the dropdown is stored in a database, but the problem is when the page is refreshed the delivered data disapears, only reappearing if you change the dropdown. How can I make the onchange event run when the page loads so that if there is already a selection, the database data will always be there, only to change if the user changes the selection? Here is the JS: Code: <script type="text/javascript"> function showCustomer(str) {var xmlhttp; if (str=="") {document.getElementById("txtHint").innerHTML=""; return;} if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest();} else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");} xmlhttp.onreadystatechange=function() {if (xmlhttp.readyState==4 && xmlhttp.status==200) {document.getElementById("txtHint").innerHTML=xmlhttp.responseText;}} xmlhttp.open("GET","getcustomer.asp?q="+str,true); xmlhttp.send();} </script> And the onchange line: Code: <SELECT Name=""customers"" id=""customers"" onchange=""showCustomer(this.value)""> Etc...

Hello, I had a php page, which contains links when I click on a link it will issue a new page, I want to make the main page to be refreshed once the new page being closed. Any suggestions? thanks I just wrote an essay to discover it had logged me out and I lost everything. Grrrrrrr. Here goes again, simplified this time. I've got a sticky footer at the bottom of the page and a spry collapsible panel which expands to reveal content on mouse over. The problem I'm facing is that the page doesn't scroll down with it, only the scroll bar gets larger to accommodate for a manual scroll down. This is kind of useless because the user might not even realise that there's extra content there in the first place if it's not automatic. My question is, what's the best javascript code to use to automatically scroll the page down when the spry tab is opened and where would I insert it? I've tried all morning with no success so far! Thanks, Nick, I'm copy pasting this post this time round, I don't trust this website now This script is activated with a onclick event in a link, the box appears and disappears, the problem is I have two links, I would like to disable Box 1 If I click Box 2 and viceversa. Any help???

So I am curious about a simple script to play a main video, with thumbnails below. What I am wanting is when you click on a thumb, it plays in the main video spot. Hope this isn't much, but donations are allowed if it is. Folks I'm using the code below to create a pop-up search box that finds text strings on a contents page. The contents page contains a list of hyperlinks each of which opens a PDF document in the same window. The search box does exactly what it's intended to do, but the problem is this: if the user clicks on "Find next" or "Find previous" once the PDF document is open, an error occurs; the same error occurs if the user then navigates back to the contents page and clicks on "Find next" or "Find previous". I'm thinking the solution must be to get the search box to close as soon as the PDF document opens, but how do I achieve this? Thanks Remster Code: <html> <head> <title>Search this page</title> <script language=JavaScript> var rng = dialogArguments.document.body.createTextRange(); rng.collapse(); function findnext(){ if (document.all.strSearch.value.length < 1) { alert("Please enter text to find."); document.frmSearch.strSearch.focus(); } else { var searchval = document.all.strSearch.value; rng.collapse(false); if (rng.findText(searchval, 1000000000)) { rng.select(); } else { alert("Finished searching page."); rng.select(false); document.frmSearch.strSearch.focus(); } } } function findprevious(){ if (document.all.strSearch.value.length < 1) { alert("Please enter text to find."); document.frmSearch.strSearch.focus(); } else { var searchval = document.all.strSearch.value; rng.collapse(true); if (rng.findText(searchval, 1000000000, 1)) { rng.select(); } else { alert("Finished searching page."); rng.select(false); document.frmSearch.strSearch.focus(); } } } </script> </head> <body bgColor=buttonface> <form name=frmSearch onsubmit="findnext();return false;" onsubmit="findprevious();return false;" action="" method=post> <table cellSpacing=0 cellPadding=0 border=0> <tr> <td style="font-size: 12px; font-family: Arial" vAlign=top noWrap align=left> <input id=strSearch style="margin-left: 15px; margin-top: 14px; width: 249;" name=strSearch><br> <button style="margin-left: 15px; margin-top: 12px; width: 120px; height: 25px;" accessKey=f onclick=findnext(); name=btnFindNext>Find next</button> <button style="margin-left: 9px; margin-top: 12px; width: 120px; height: 25px;" accessKey=f onclick=findprevious(); name=btnFindPrevious>Find previous</button></br> </td> </tr> </table> </form> </body> </html> how i can refresh my main history page without page refresh alert message? i am using the following code on the submitpage.asp <%response.write ("<script>window.location.reload(history.go(-2));</script>")%> i got the attached message when it refreshes the main page. is there is a way to refresh directly without this message? We are building an opera extension in which we are trying to use the document object property (document.body.innerHTML) in order to obtain the source of the main page of a site. In most cases it provides us with the correct page source but for certain sites (ones that have multiple document layers), it doesn't return the top most document. For instance, for the site (https://www.pcisecuritystandards.org/) we would like to source for the main page that is displayed but once the entire page is loaded, the document property would display the source for another layer (https://s7.addthis.com/static/r07/sh...rev=86981&xd=1) This perhaps has to do with how opera loads the document layers in a page. We did not face any issue with any other browser How can we obtain the source of the main page (https://www.pcisecuritystandards.org/) using the document object in Opera ? Hi I want to create a popup that is completely contained within the page (so i guess its not really a popup). I'm looking for something where if a button is clicked, a small box will come up in the current window and become the active window, while the original window is visible but not active. It's hard to explain, but its a popup that is contained in the same window. And when the user presses okay or cancel on the "popup" window. They return to where they were in the original window. Is this possible? How would I do it? Thanks Hi I have seen this popup in a registration form. I think it's using jquery but I don't know how can I make some thing like this . I want to put a registration form in it ( ajax registration ) when the popup appear , around it will became dark how can I do so ? thanks Hello. It is Friday. I thought this will be a simple question, but it seen like hard to find a fast and simple solution. I am working on an online sign in tool. Two browser windows are open at the same time. One is for people to sign in with password and submit their information; another one is for Administrator to see who sign in. I am trying to refresh the Administrator page whenever user finished sign in and submitted their information. These two pages cannot be parent and child page. What will be the easiest way to solve this in ColdFusion or JavaScript? Thank you so much for your time. Have a wonderful weekend.

Thanks in advance! Thorbob I have a page that loads a fancybox popup and it works perfectly with the cookie for setting ho many days to show. the problem i have is that i need it to show 1 every 24 hours over a 3 day period. once the 3rd day is over and the user sees the window for the 3rd day i need a cookie set to never show the window again. here is my code as it sits now. I have worked with this for a couple of days on and off and it is above my head for sure. any help is appreciated. $(function() { if ($.cookie('moment_comm')) { // it hasn't been 1 day yet } else { $("#autostart").fancybox({'overlayShow':true,frameWidth: 840,frameHeight:360}).trigger('click'); } } ); $('#autostart').live('click', function(e) { e.preventDefault(); $.cookie("moment_comm", "true", { path: '/', expires: 1 }); $.fancybox.close() }); Hi All, I have a script that is called by the onchange event on my text field (it compares the date entered into the field and issues an alert if the date is earlier than the current date). This worked great on my data entry form but I also want to use the same script in my update form. In the update form the text field is already receiving a value via php: Code: <input name="DateNeeded" type="text" class="formField" id="DateNeeded" onchange="checkDate(this)" value="<?php echo $row_rstRequestDetails['DateNeeded']; ?>" /> and this is causing my onchange event to fire when the page is loaded. Is there a way to suppress the onchange event for the initial page load? Thanks, Ken Alright, so I'm working on a script, and I'm simply using the following code: document.getElementById("element").onclick = alert("hello"); When I load the page, the alert fires instantaneously. I'm completely stumped. I've checked everything in my not too extensive Javascript file, and it looks fine. What common errors could cause this? our requirement is client wants to know howmany users leaving the main page without entering data in the application page.at that time we need to show the css popup overlay. in the following scenarios overlay should pop up. 1)when user leaves the page.(e.g. type other address in the address bar).bascially user shy away from the browser. 2)clicks browser close button. we will show one css popup overlay(not browser popup) and in the back ground main application will be greyed out.this overlay consists of some text fields and some buttons will be there and parallely in the back ground we will execute AJAX call. can we accomplish this requirement??is yes how?will it work in all browsers? my concern is how to prevent the browser from closing(e.g.when user chooses browser X button) when css overlay comes up. Hi. I have a question about java script code. I'm creating a website with frames. Within the main page frame, there are tables in the main content page. When I created the website, it fit perfectly in the browser window of my smaller laptop. I just checked it out on my old G5 and the images/pages are too big and either cut off or scroll bars appear (which is not what I want) So I wanted to know what code I put in my files and where to put it? Also, what pages does it need to be in? the main frame index page? the specific pages that fit within the frames? some are images that load in the frames? would i need to create an .html for those and then have the .jpg load so that it can be resized? I need the main page to be resized to fit the browser as well as the pages in the frames to fit. Can you help? Thanks |
