JavaScript - Execute A Script When A User Clicks The Button
Hi Everyone,
I want to execute a script when the user clicks the button. Currently in my html doc. i have the button declared. <input type="button" id ="button" onclick='notEmpty() value="Play"/> When the button is clicked, i execute the notEmpty() function and I want to execute a script inside the notEmpty(). How can i do this? Thanks, Praveen Similar TutorialsHi, "This happens only in chrome browser" I am trying to design a website and it has a couple of radio button on the first page. I selected one radio button and navigated to the next page. On my second page, if i hit back button, the first page show the radio option that i selected(which is correct) but when I hit save and continue it throws a JS error "please select one option". Chrome forces me to re-click the radio option again. The application is MVC 3.5, C# Here is the snippet of the ascx Code: <%= Html.RadioButton("radAccnt", "abc", Account != null ? (entity != string.Empty ? (entity.Substring(0, 3).Equals("abc") ? true : false) : false) : false, new { id = "radAbc", onClick = "SetEntity('abc');", onBlur = "javascript:ValidateOnBlur(\"ValidateAccount('true');\");" })%>
I had a alert in SetEntity(Value) function and value is empty when the back button is clicked. I did some research and found that Chrome does not cache the form data. If this is true is there a work around for this? Please help. Thanks. All, I have a script that runs some jQuery and appends it to a <div>. I only want this script executed if a user is using IE7 or higher since jQuery doesn't work with IE6. How can I do that? Also, if they aren't using IE7 or higher I don't wnat to display the <div> that the results go into. How would I go about doing this? Thanks! Hello I want to add something to my web site. when the user clicks to download. i want to see a pop up screen which says your download has started. <script type="text/javascript"> function show_alert() { alert("Your Download Started!"); } </script> <input type="button" onclick="show_alert()" onclick="get value="Download" /> I dont get where should i put the download link I want to send a simple email with just email & subject only when the user clicks a link that opens a pdf. I'm thinking javascript is the best way to do this but I have no idea how. I have googled it a bunch but most information is about getting an email when someone clicks a link you send in an email. I don't want that. This is on a website. I'm not sure if php would be better to use. Any help would be most appreciated!
How to detect if the user clicked cancel while uploading a file ? Is there an event for it?
I found this code sample that when a user clicks somewhere on the image, then an "X" will appear. I would like to have the "X"s remain visible even when the user clicks on a different area of the image. As you can imagine, a user clicks clicks clicks then there are "X"s everywhere. How do I do this? Do I need to create more "div" tags with the mouse click locations? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Mouse position</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta http-equiv="Content-Style-Type" content="text/css"> <meta http-equiv="Content-Script-Type" content="text/javascript"> <script language="JavaScript" type="text/JavaScript"> var posx; var posy; function getMouse(e){ posx=0;posy=0; var ev=(!e)?window.event:e;//IE:Moz if (ev.pageX){//Moz posx=ev.pageX+window.pageXOffset; posy=ev.pageY+window.pageYOffset; } else if(ev.clientX){//IE posx=ev.clientX+document.body.scrollLeft; posy=ev.clientY+document.body.scrollTop; } else{return false}//old browsers } function showP(){ document.getElementById("div2").style.visibility="visible"; document.getElementById("div2").style.top =(posy-10)+'px'; document.getElementById("div2").style.left=(posx-6)+'px'; } </script> <style type="text/css"> .div1 {position:absolute;top:100px;left:100px;visibility:visible;z-index:5} .div2 {position:absolute;top:0px;left:0px;visibility:hidden;z-index:1;color:black;} .div3 {position:absolute;visibility:hidden;z-index:10;font-family:monospace;font-size:20px;font-weight:900;color:black;} </style> </head> <body onmousemove="getMouse(event)"> <div id="div1" class="div1"> <img src="./yourImage.jpg" onclick="showP()"> </div> <div id="div2" class="div3"> X </div> </body> </html> Hey, I have a page at http://www.webdev70.cocc-webdev.org/contact.html where I have styling on the radio and check boxes. I'm working on another project for class now where I want onclick or onchange functions in the radio buttons. When the radio buttons have the class="styled" on them, the function will not execute. When that's removed, they do. Here is the javascript for the styling: Code: var checkboxHeight = "25";
var radioHeight = "25";
var selectWidth = "190";
document.write('<style type="text/css">input.styled { display: none; } select.styled { position: relative; width: ' + selectWidth + 'px; opacity: 0; filter: alpha(opacity=0); z-index: 5; } .disabled { opacity: 0.5; filter: alpha(opacity=50); }</style>');

The code is way over my head so I'm not sure where the problem is, or if it could be fixed. This is what one of my radio buttons looks like: <input type="radio" name="puppy" value="1" class="styled" onchange="puppycheck()">Black and White Puppy If the style tag is removed it works perfectly. There is CSS too, but I don't think the problem is in there. HI peers, i need to run a sql query fromjavascript onclick button and display data in a textarea . is this possible ? than you . I guess this case applies to both popup windows opened by window.open() and by showModalWindow(). I have two buttons in popup window, "Cancel" and "Save". If the user clicks either button, there is a "process" at parent window before close() at popup being called. The problem now is, if the user click the "X" sign at top right corner of that popup window, how to trigger the "process"? I think I can do nothing in popup window since the closure is unexpected programmatically. Can I put some kind of listener in parent window to detect if popup is closed? How would I track how many times a user hit the OK button when prompted with a message using document.writeln?
Ok so im new to javascript and I have a button in an interface for an app. It's like drag and drop and i want this button to link you to a certain website searching for what the user types in the searchField1 box. The button is button16. Such as you type dogs into the text box and you click the google button among other search engines and it will redirect you to a google search doing a search for dogs. But how do I make this button search google and search for whats in searchField1. I would really appreciate the help. Im looking everywhere to learn this but just cant find it. If you could tell me how or send me a link to a tutorial that would be great. Thanks! Here is the code: I don't know where and what to add to do that. Please help. I've been handed an html document that contains a centered, scrollable <iframe> element with a static height and width. This iframe element displays a simple html document that houses the 'terms of service' text. Their goal is to have it to where the <a href> link at the bottom that is shown to the user as 'next' is disabled until the user scrolls to the bottom of the terms of agreement box. The clickable link could be a button, image or text (no preference). They have to have it this way for legal reasons and radio buttons or checkboxes will not suffice unfortunately. Question: What is the best way to go about doing this that seems to be cross-browser friendly (especially IE7). I offer $10 via paypal for well commented method/script. I'm looking for a javascript that will detect the following user information: OS version, browser version, quicktime + flash + adobe reader + java + windows media player + sliverlight versions of the users computer. I am looking to put this script into an HTML page and the information be displayed so the user can see what versions of the programs they have. I don't know a whole lot about javascript so if there is a script i could copy and paste, that would be great!!!! Also, is it possible to have the current versions of these programs displayed and automatically updated as well so the user can compare the version they have with the most current version of the program? Any help would be great! Thanks!!! Let me first say I am not a java programmer but I can follow the tutorials and get some things to work. Here I am trying to create a password protected page, realizing the level of security is not very high. This page of code, link1.html, will be blank and if the correct password is entered then I want to automatically link to another page, barcs.html.

Yes - I need a script that will validate user input against a text file - exactly like the one in the left sidebar at http://www.oilpatchfuel.com/Pages/Welcome.aspx titled "Delivery Area". Thanks! Hi, Please i am not getting clear understanding of a javascript code to redirect user to a different web page based on the day of the week. Please i have search for many script and not getting clear understanding from their code.I have also try several code myself but nothing good has come from it. Please can someone help me and write a descriptive code for me to understand better.I really plead you and your to help me...but i belief the Lord God will bless you for your time helping me. looking forward to here from you. Thank you. Clement Osei Hi, See I have called a function in onchange event of a dropdownlist.What happens in the onchange function is that if the value for dropdown has already been entered once, then an alert message will be shown. The problem I have is, if the value has been already entered, when I try to change the value in dropdown, dropdownlist gets displayed (expands) and an alert message gets displayed. When I click "OK" of alertbox first the dropdown gets back to it original form and only on the next click alert box goes. What I need is everything should happen in a single click itself. I wanted to make it so that a button on the webpage validates a word that a user types into a prompt box that pops up when they open the webpage. For example, user goes on website, prompt box opens, user types in word then presses OK. On the webpage he clicks the button, which calls a while function to check if the word has a P at the start, a J somewhere in it, and is longer than 8 characters. Code: <script type="text/javascript">
var strWord;
function validateWord()
{
while(strWord == document.formname.validateWord.value.length > 8 && var iChars =
"JP";)
{
"alert(Correct)"
value="Word Alert">
}
}
</SCRIPT>
I've been trying this script but with no luck and cant tell whats wrong with it. Any ideas? Hello, I've been working on creating a script that zooms the entire webpage. Other than using "CTRL" + "+" keys (generally compatible with all browsers) to zoom in inside a web browser, I want to put it in a different format, as a button; it would be even easier to use. The problem is that I can't figure out how to make it work/ why it does not work. The following is my code: Code: <html>
<head>
<script type = "text/javascript">
document.onkeydown = function(zoomin) {
var key;
zoomin = zoomin || event;
key = zoomin.keyCode;
key == 43;
return false;
if (key == 17) {
return true;
function(zoomin){;
return false;
}
}
}</script>
</head>
<body>
<h1>Is this appearing to get bigger?</h1>
<button onclick="javascript: function('zoomin');">Zoom in</button>
</body>
</html>
Basically I was trying to use a DEC code as the code for the "CTRL" and "+" keys; then put them into a function. The "return true" under the IF statement means that I want it to hold so that the "+" key can be read as part of the script, and therefore make the page zoom in. Once that happens, it returns false. I would appreciate any help/ suggestions. I will also try to look for a way to reset the page (100%) or zoom out as well. Hi Guys, I was wondering if I could have some help. Its coding for the left side of a frame set to display in the right side. Im pulling my hair out! Thanks Code: <html>
<head>
<script type="text/javascript">
function go()
{
var go="none";
if (document.buttons.option[0].checked)
go=button.option[0].value;
if (document.buttons.option[1].checked)
go=buttons.option[1].value;
if (document.buttons.option[2].checked)
go=buttons.option[2].value;
parent.rightframe.location=go;
}
</script>
</head>
<body>
<form name="buttons" id="buttons">
<input type="radio" name="option" value="cit.html" checked="checked">CIT</input>
<br />
<input type="radio" name="option" value="currency.html">Currency</input>
<br />
<input type="radio" name="option" value="staffsurvey.html">Staff Survey</input>
<br />
<input type="radio" name="option" value="game.html">Game</input>
<br />
<input type="button" value="Go" onClick="go();"</input>
</form>
</body>
</html>
