This is what I have so far, but I don't think I'm doing it the right way. Any suggestions? PHP Code: <?php function phpQuery(){ $query = mysql_query("INSERT INTO mytable VALUES('','name','email')"); } ?> <script type="text/javascript"> function delayQueries() { timeoutID = window.setTimeout(doQueries, 2000); } function doQueries() { var runQuery = "<?php phpQuery(); ?>"; } </script> I made a mouseover event of a caption on a picture, when I hover the opacity of the background color of the hover and the text goes down. What I want is that when I hover over the image which the caption is floating on, the onmouseover event gets activite. For an imaginary example: Code: function unhighlight(x) {
x.style.backgroundColor="transparent"
}
Function ActivationFuction()
{
activate.function="unhighlight"
}
thanks Dear all I came across the following very simple code for dragging a square around using javascript. It is drawn on the html5 canvas. Despite being very simple it has certainly exposed some gaps in my pretty flakey javascript knowledge. I am generally ok with the idea of drag and drop (i.e. start drag on mouse click, stop drag on mouse release) but my questions are as follows: (1) I cannot see where the variable e is defined, yet it is used all the time. (2) In the init funciton at the bottom, an onmousedown listener seems to be attached to the canvas. However it equals the function myDown, but myDown doesn't have parentheses after it. So the myDown function is not actually going to be exectuted. So what is it doing instead? Thanks in advance. I have tried to research this myself but haven't had any success yet.

Hi everyone, I am pretty new at javascript OOP. I have a javascript file that has plenty of javascript functions, variables, arrays, etc. I need to convert this into an object. Here is an example: Code: var myvar1 = '';
var myvar2 = new array();
var myvar3 = new array();
var myvar4;
var myvar5 = 60;
var myvar6 = '';
function myfunc1(){
myvar1 = 'hello';
return myvar1;
}
function myfunc2(somenum=0){
myvar5 = somenum;
//calling myfunc1() from within this function.
//do something in here
}
function myfunc3(){
//calling myfunc1() from within this function.
for(i=0;i<somelength;i++){
myvar2 = myvar3[i]; (something to put into the array)
}
}
1. I need to create an object and put ALL the varibles (myvar1 - myvar5) in that object. 2. Then the first two functions "myfunc1 and myfunc2" inside the same object. 2. And the function myfunc3 needs to sit OUTSIDE my object as a regular javascript function. It calls on myfunc1 (which is inside the object) and also inserts data into myvar2 (which is classified inside the object) and myvar3 (which is classified inside the object as well). This is what i came up with, but it's not going well: Code: var myobj1 = function(){
this.myvar1 = '';
this.myvar2 = new array();
this.myvar3 = new array();
this.myvar4;
this.myvar5 = 60;
this.myvar6 = '';
var myfunc1 = function(){
this.myvar1 = 'hello';
return this.myvar1;
}
var myfunc2 = function(somenum=0;){
this.myvar5 = somenum;
//calling this.myfunc1() from within this function.
//do something in here
}
}
function myfunc3(){
//calling mynewobj.myfunc1() from within this function.
for(i=0;i<somelength;i++){
mynewobj.myvar2 = mynewobj.myvar3[i]; (something to put into the array)
}
}
var mynewobj = myobj1;
HELP.....!!!! i really want to get into object oriented world, so thanks in advance. Hi I am trying to get javascript to update a database for me. The reason is I need to use JS and not ASP is because I need to update whenever a user clicks on a button and from what I am told ASP can not do this. I tried following an example, and this is what I came up with. However I get the errors Error: Object expected and Excptected Hexadecimal Digit. Here is the code Code: <script language=javascript>
function update()
{
var adoConn = new ActiveXObject("ADODB.Connection");
var adoRS = new ActiveXObject("ADODB.Recordset");
adoConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='\\data\user.mdb'");
adoRS.Open("Select * From ptotbl Where ID = 454");
adoRS.Edit;
adoRS.Fields("Delete").value = "True";
adoRS.Update;
adoRS.Close();
adoConn.Close();
}
Thanks Hi There, I'm working on an application that potentially gets 1000s of geolocation queries per day and if I don this (as I've done it till now) in php, it works fine but I quickly run into OVER_QUERY_LIMIT error from the google map apis. Thus I think I'd better do it in javascript and just send the coordinates to the server for caching rather than querying from the server's IP. Now the url that sends back the location information looks like this: http://www.google.com/url?sa=D&q=htt...s3czv6-nMr_nbw and I was wondering how I can send a request to this url and parse the xml string that's returned with JavaScript to pass it on to a php (probably by get variables). Is there a handy method that's compatible accross a bunch of browsers incl. mobile ones? Thanks very much for some input! Ron Hello I'm trying to create a graph that will accept 1 or multiple data sets depending on what the user selects. How can I add get the data into the graph using a loop? I want it to add a line for each selection. Thanks // Graph Data ############################################## var graphData = [{ // Visits data : <?php echo '['.implode($data).'],'?> color: '#71c73e' }, { // Visits data : <?php echo '['.implode($data_1).'],'?> color: '#red' }, ]; Hi I am trying to create a query string similar to the one available he http://andrewu.co.uk/tools/request/e.../example1.html The problem that I am having is that I have more than one button on my page and even though my id's are unique all of my data is displaying on the action page at the same time. The code that i am using for my buttons is: Code: <label for="name_1">Name:</label>
<input type="text" name="name1" id="name_1" tabindex="1" size="40" value="Donald Duck" />
<br />
<br />
<input type="submit" id='view1' value="Submit" tabindex="2" />
<label for="name_1">Name:</label>
<input type="text" name="name2" id="name_2" tabindex="1" size="40" value="Mickey Mouse" />
<br />
<br />
<input type="submit" id='view2' value="View" tabindex="2" />
I have a lot more than 2 buttons on my page. when a button is clicked I would like to be able to get the values from the query string and only see the values for the button that was clicked like this one: http://andrewu.co.uk/tools/request/e...ndrew+Urquhart but instead I am getting Name: Donald Duck, Name: Mickey Mouse. What would I have to add or change to obtain just one Name to display at a time but have it be different depending on which button is pressed? Hi guys, been running into some problems with all IE browsers and my jQuery Gallery from Galleryview. Background: I am using Java to do an image search and build up some HTML including the calls to run the galleryview scripts and return this back to the page using document.write() When I use the simple structure of placing the scripts and parameters into a sample page: Code: Code: <body>
<script type="text/javascript" src="http://spaceforaname.com/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="http://spaceforaname.com/js/jquery.easing.1.3.js"></script>
<script type="text/javascript" src="http://spaceforaname.com/js/jquery-galleryview-1.1/jquery.galleryview-1.1.js"></script>
<script type="text/javascript" src="http://spaceforaname.com/js/jquery-galleryview-1.1/jquery.timers-1.1.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#photos').galleryView({
panel_width: 800,
panel_height: 300,
frame_width: 100,
frame_height: 100
});
});
</script>
It works fine. When I try and pull all the scripts out of the page and inject them back in using document.write() I get an error on IE: Code: Code: sb.append("(function(){ document.write('" +
" <script type=\"text/javascript\" src=\"http://spaceforaname.com/js/jquery-1.3.2.min.js\"></script> " +
" <script type=\"text/javascript\" src=\"http://spaceforaname.com/js/jquery.easing.1.3.js\"></script> " +
" <script type=\"text/javascript\" src=\"http://spaceforaname.com/js/jquery-galleryview-1.1/jquery.galleryview-1.1.js\"></script> " +
" <script type=\"text/javascript\" src=\"http://spaceforaname.com/js/jquery-galleryview-1.1/jquery.timers-1.1.2.js\"></script> " +
" <script type=\"text/javascript\"> " +
" $(document).ready(function(){ " +
" $(\"#photos\").galleryView({ " +
" panel_width: 800, " +
" panel_height: 300, " +
" frame_width: 100, " +
" frame_height: 100 " +
" }); " +
" }); " +
" </script> " +............+
"')})()");
The variable sb is a StringBuffer and is formatted and returned: Code: Code: nextPage.setValue(sb.toString()); nextPage.setEscapeHTML(false); return nextPage; This particular error in this case in IE(8) is: Object expected which I think is referring to the jQuery as the resulting images are displayed just not in Galleryview style. This is really wracking my brains and any and all help is appreciated. D. I have noooo idea if I am even posting this in the correct area, let alone the correct site. If not I apologize and maybe someone could direct me elsewhere. I am trying to add a custom search into my site. http://www.jeffknowsloans.com you can see it about the middle of the page. I am using the following script to do so. Code: <script type="text/javascript">
function dosearch() {
var sf=document.searchform;
var submitto = sf.sengines.options[sf.sengines.selectedIndex].value + escape(sf.searchterms.value);
window.location.href = submitto;
return false;
}
</script>
<form name="searchform" onSubmit="return dosearch();">
Select County
<select name="sengines">
<option value="http://www2.co.washington.mn.us/opip/mod/addresssrch/result.asp?housenum=&street=" selected>Washington</option>
<option value="http://rrinfo.co.ramsey.mn.us/public/characteristic/PropertySearchResults.aspx?pin=&Nbr=&Street=&pg=1" selected>Ramsey</option>
<option value="http://www.altavista.com/web/results?q=">Alta Vista</option>
<option value="http://www.dogpile.com/info.dogpl/search/web/">Dogpile</option>
</select>
Street Address:
<input type="text" name="searchterms">
<input type="submit" name="SearchSubmit" value="Search">
</form>
here is the problem i am running into. I dont know how to ignore or add certain parts of the search when it sends. for example. take a look at Code: <option value="http://rrinfo.co.ramsey.mn.us/public/characteristic/PropertySearchResults.aspx?pin=&Nbr=&Street=&pg=1" selected>Ramsey</option> When i try to do a search under this drop down selection it doesnt work. because it needs the &pg=1 to be added to the users search request. Meaning if I set it to Code: http://rrinfo.co.ramsey.mn.us/public/characteristic/PropertySearchResults.aspx?pin=&Nbr=&Street= they type in their street name and the street name inputs into the search query but it wont fully work because it doesnt add the &pg=1 after it all. how in the world do I get it to add things like that? ie how do i tell it to add certain strings that the outside source requires? like blank=&blank= or how do i get it to ignore certain &blank= commands. another example taking a look at Code: <option value="http://www2.co.washington.mn.us/opip/mod/addresssrch/result.asp?housenum=&street=" selected>Washington</option> this search function should technically be Code: <option value="http://www2.co.washington.mn.us/opip/mod/addresssrch/result.asp?" selected>Washington</option> however since i dont know how to add certain functions to the search i have to skip the housenum option. that means my customers cant search by street number. I want them to be able to type in their house number and their street address and it will change to what each seperate (outside) search engine needs. Does this make any sense at all? Hi everyone, i am developing a facebook application and here i am, struggling with this piece of code. I have this php query result he $id = $facebook->api(array('method' => 'fql.query', 'query' => "SELECT uid FROM user WHERE uid IN( SELECT uid FROM page_fan WHERE page_id='411133928921438' AND uid IN ( SELECT uid2 FROM friend WHERE uid1 = me() ))")); And i need to save it as an array like: var user_ids = [x,y,z] etc etc... I have used the json_encode but it isn't working... here is my code.. Code: var user_ids = <?php echo json_encode($id); ?>; How can i retrieve the query results, the id's in an array like i mentioned above? Please help me... I have an array from a sql query that I need to use as variables in a javascript function. I have created the array, used JSON_ENCODE to bring the information into javascript, and so far everything works correctly. I am trying to use a list menu in html to select one on the indexes of the array so I can pass the information from the index to a javascript function. Here is the javascript function: Code: function selectTable(item_id)
{
var media = eval(<? echo json_encode($paperTable); ?>);
var click_k_1=media[item_id]["click_k_1"];
var click_k_501=media[item_id]["click_k_501"];
var click_c_1=media[item_id]["click_c_1"];
var click_c_51=media[item_id["click_c_51"];
var click_c_101=media[item_id]["click_c_101"];
}
Here is the list menu coding: Code: <select name="pprSel" size="1" id="pprSel" onChange="selectTable(this.value);" > <option value="204226">20# Bond</option> <option value="204788">70# White</option> <option value="204823">80# White</option> </select> Here is the source file results from the browser: Quote: function selectTable(item_id) { var media = eval({"1":{"item_id":"204226","item_description":"20# Bond","click_k_1":"0.1100","click_k_501":"0.0730","click_c_1":null,"click_c_51":null,"click_c_101":n ull},"2":{"item_id":"204788","item_description":"70# White","click_k_1":"0.1149","click_k_501":"0.0779","click_c_1":"0.8789","click_c_51":"0.5539","click _c_101":"0.3589"},"3":{"item_id":"204823","item_description":"80# White","click_k_1":"0.1591","click_k_501":"0.1221","click_c_1":"0.9231","click_c_51":"0.5981","click _c_101":"0.4031"}}); } I have tried a couple of different ways to pass one of the variables to a text field on the html form as an error check, with no success: Code: document.quote.data.value=media[item_id]["click_k_1"]; document.quote.data.value=click_k_1; The text field on the html form is id='data', the form is id='quote'. the only thing I can think of for the reason I am not getting anything in my text field is that my variable is not getting set up properly. Can anyone help? TIA HI peers, i need to run a sql query fromjavascript onclick button and display data in a textarea . is this possible ? than you . i am developing a facebook application and i have this code here which queries the user id and other information: Code: $users = $facebook->api(array('method' => 'fql.query',

Help me with this... long story short, I do work for a church, a charity asked me to fix some errors at their web site...1 problem arose and JavaScript is not my strong suite..they have an newsletter request form, just enter your email and your on their newsletter list, as you can see from the code below there is a problem, no valid email verify routine, if you just enter a space in the form, it will accept the info and send a blank request to the charity where an email addie should be... no clue how to fix, as I said javascript is not something I do at all....any help appreciated. kenrich ======================= <script type="text/javascript"> $(function(){ $("#rform").submit(function(){return false;}); $("#rsubmit").click(function(){ if($("input#s").val() != "" && $("input#s").val() != 'Enter Email Address'){ $.get("/rsignup.php?email="+$("input#s").val(), function(data){ $("#rdiv").html(data).css("margin-top","15px"); }); } else { alert('Please enter your email address to subscribe'); } }); }); </script> <!-- BEGIN Form --> <div style="text-align: left;margin: 20px 0 -10px 10px;font-weight:bold;">Email Newsletter:</div> <div id="newsletterdiv" style="height:25px;"> <form name="optin" action="#" onsubmit="return false;" method="post" style="margin-bottom:2;" id="newsletterform"> <input type="hidden" name="vff" value="103"> <input type="hidden" name="vpp" value="i"> <div> <input value="Enter Email Address" onfocus="if (this.value == 'Enter Email Address') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Enter Email Address';}" name="ea" id="s" type="text"> <input id="newslettersubmit" value=" " type="submit" name="go"> </div> </form> </div> <!-- END Form --> The code is JScript .NET, which is basically a .NET version of Javascript. Regardless of language, Anyone with appending type of skill can answer my question. The problem is, when I keep issuing the request it keeps appending over and over again Code: if (oSession.uriContains("search?q="))
{
var str = oSession.fullUrl;
var sAppend = "+test1+test2+test3";
if (!oSession.uriContains(sAppend))
{
oSession.fullUrl = str.replace( "search?q=","search?q="+sAppend);
}
}
Can you please give me an example? I'm still new to programming. Thank you If I use function or Function to create a javascript function, does it make any difference ? Whats the difference between two and in which situation shall I use either ? Likewise whats the difference between event and Event objects of JavaScript ? Thanks |
