JavaScript - Update Mysql From Js Function
Hi Guys,
What i'm attempting to do is update a mysql database through a javascript function, so when i click on <a href='onclick="return myfunction();"'></a> PHP Code: function myfunction(affURL) { if (confirm('You will now be redirected to the purchase page, continue?')) { // Need a way to log things, update mysql with vars passed through var l = screen.availWidth / 2 - 450; var t = screen.availHeight / 2 - 320; var win = window.open(affURL, 'payPopupMain', 'width=900,height=650,left='+l+',top='+t+',scrollbars=1'); } else { // Send them back to the payment.php page window.location('payment.php'); } } The code above opens up a browser for the user, but i also want to update mysql without the user seeing any of it, so all they see if the browser popup, and behind the scenes the script updates mysql with a few variables any help on what i would need to do would be appeciated. thanks guys Graham Similar TutorialsI want to update the variables in the progress bar HTML5 has to offer. Here is the function I have so far (It has been modified and shortened for the means of this post): Code: function calcProgress()
{
var num1 = Number(document.form.num1.value);
var num2 = Number(document.form.num2.value);
Number(document.form.progress.value) = num1
Number(document.form.progress.max) = num2;
}
This is the form: Code: <form name="form"> <input name="num1" onChange="calcProgress()" type="text" value="0" /> / <input name="num2" type="text" value="0" onChange="calcProgress()" size="1"> <br> <progress name="progress" id="progress" min="0" value="0" max=""></progress> </form> Hi everyone. I've managed to create everything to work correctly using javascript on my site, except I'm trying to find a way so that a certain function is called on non-stop. Or at least every time the mouse moves. The site is http://www.goformat.com/ What I'm trying to do is make it so that the words, characters, and lines counter at the top of the text area updates on its own. Right now, it updates onkeyup. However, when you click a button, to say, delete all the letters, they don't update unless you do another onkeyup action. The function that updates the words, characters, and lines is "countall()". so i tried putting a onfocus="countall()" and also a onmouseout="countall()" with one of the buttons, But none of it is working. Is there some kind of javascript code that sets the page to keep performing a function after a set amount of time? Or at least one that will work with the buttons so that the "countall()" function is called on after pushing a button? Thanks you very much everyone for the help, any suggestions are very much appreciated. Hello. This is very long and I think if you look at code it might be quicker. If not, then please read along. Here is the code and the problem: Code: function addtwoboxes
{
get values from two text boxes, one about width, the other one about height,
and store each in a variable; a=width; b=height
checkifwidthproblem(); //to see if the boxes are empty and with numbers
checkifheightproblem(); //to see if the boxes are empty and with numbers
if (width_not_ok==false && height_not_ok==false)
{
Go Ahead and do calculations and other things
}
function checkifwidthproblem()
{
width_not_ok=false;
if problems with the data in the textbox (the a variable is being checked).
{
bring up an alert box
width_not_ok=true;
}
} //end of checkifwidthproblem function
function checkifheightproblem()
{
height_not_ok=false;
if problems with the data in the textbox (the b variable is being checked)
{
bring up an alert box
height_not_ok=true;
}
} //end of checkifheightproblem function
I would like this function to be setup the same way as the addtwoboxes function, but right
now I am only calling up the checkifwidthproblem function, and it doesn't execute and the
form gets submitted. The fillInvoiceNumber function can be called because if I place only
an alert of Hello in it, it comes up, and then the form gets submitted. If it do get this
working, I would also need to be sure that it is seeing the results of the variables
width_not_ok and height_not_ok, just as they are for the addtwoboxes function.
function fillInvoiceNumber()
checkifwidthproblem(); //to see if the boxes are empty and with numbers
checkifheightproblem(); //to see if the boxes are empty and with numbers
if (width_not_ok==false && height_not_ok==false)
{
Go Ahead and do calculations and other things
]
This is going to be a bit long, but it's the only way I can be sure of that I have covered everything, so please bear with me and help me out. Thanks. Please Provide Solution Using my way First, Then suggest Better Ways: O.k. Before I post the problem, I know, since I took program classes years ago and since I have done a little research here and here, that there are better, more efficient, and tidier ways to do what I am doing, but I have started already this way and would like to continue this way. I will ask what's the better way to do this in another thread, unless 1) you feel like explaining the bettery way and 2) it's not too long or complicated, but AFTER you have provided me with a solution to doing it my way. The Setup / What My Form is Supposed to Do: I have a form with two buttons. The user has to enter some information into the form and then click the button to have some calculations done and for other text fields to automatically filled in. After that, the user has to click submit. A note about the submit button: The type is image and the name says submit. The form line has the following: <form target="abcco" action="https://www.domainname.com" method="post" id="Form" onsubmit="fillInvoiceNumber()"> I will explain what the fillInvoiceNumber() is doing later on. Data Validation / Verification: 1) I want to ensure that when the user clicks the first button, let's call it GetPrices to make things easier, that it checks to see if data is enterted into the textboxes and that it is the right kind of data. 2) After the GetPrices button is clicked, the user can then enter nonsense into the textboxes and click submit or, never click the GetPrices button, the first button to begin with, and so junk will be submitted. This is what I have going on: For the GetPrices button, I have the following: onclick="addtwoboxes() (the names I have aren't fully descriptive of all that's going on, as I do have more things happening, but for now I have left them like that). in the addtwoboxes function I have it calling up two functions, each for a textbox in which the user has to enter width in one and height in another, and if the textboxes are not empty and have the correct data in them, then the calcuations for the addtwoboxes take place; if not, nothing happens (regarding the calculations; an alert box comes up for either or both of the functions in the addtwoboxes function if something is wrong). So, the two functions that are called in the addtwoboxes() function are checkifwidthproblem() checkifheighthproblem() which I am calling just like that but with a semicolon to the end of each one. This next now is one of the areas where I do believe this can be combined, since only one value is changing, but I will leave it like this for now. The checkifwidthproblem() function starts of with a variable:width_not_ok=false; (after doing some research, I see that this is often set the opposite way or not set at all) if something is wrong with the data entered into the width textbox, an alert box with a message comes up, and I then have the following variable: width_not_ok=false; For the checkifheighthproblem(), it's basically the same as the width problem, except, with it's own set of variables. I had the same ones as the width one, but if things were not ok with the width textbox, but o.k. with the height textbox, the calculations were taking place. So, because of this I used new variables in the height function and had an if statement check both variables for false. So, the checkifheighthproblem() starts of with the variable: height_not_ok=false and if there is a problem with the data entered into the height textbox, an alert box comes up and the variable height_not_ok=true is set. When the user presses the GetPrices button, this function works excellently. Everything goes as it should. The problem is when the form is being submitted. I would like the textboxes to be rechecked. So, right now I have a function called fillInvoiceNumber() in which it is joining two strings together after getting their values from a drop down menu. This has to be done at the time of submission only for the page that's processing the results to have them interpreted the way I want it to. Prior to joining those strings, I would like it check and see if everything is o.k. with the two textboxes by calling the two functions of that check height and width and if they are not, for the alert boxes to come up, for the joining of the strings to not take place, and for the form to not be submitted. However, the fillInvoiceNumber() function is not executing either function at all. If it does work, I would also need to be sure that it is seeing the results of the variables width_not_ok and height_not_ok. Hi, I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it? intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\' I am posting my javascript function he <a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a> function OpenDocPreview(url, docname) { alert('message from search base : ' + url + ' ' + docname); } thank you, I was working on a tutorial for some ajax uploading stuff and I ran across a new function syntax I don't recognize. I am not a Javascript pro, but I am not a newbie either. here is the code I am working on: Code: function handleFileSelect(e){
var files = e.target.files;
var output = [];
for(var i=0,f;f=files[i];i++){
if(f.type.match('image.*')){
var reader = new FileReader();
reader.onload = (function(theFile){
return function(e){
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="',e.target.result,'" title="',theFile.nbame,'" />'].join('');
document.getElementById('list').insertBefore(span,null);
};
})(f);
reader.readAsDataURL(f);
}
}
document.getElementById('list').innerHTML = '<ul>'+output.join('')+'</ul>';
}
document.getElementById('files').addEventListener('change',handleFileSelect,false);
To be a little more clear, the code in question is that is the very middle. The syntax I don't understand is: Code: class.event = (function(arguments){
//stuff you put in a function...
})(more Arguments?);
I tried to customize a simple one to learn for myself and I wrote this: Code: var a = 'A';
var b = 'B';
test = (function(t){
alert(t);
alert(b);
})(b);
test(a);
The browser would alert 'B' and that's it. The console would tell me that 'test is not a function.' OK, so I am confused. The topmost code works. What I am wondering is what the syntax is called for creating a function (or event listener?) that way, and how it works. Although if I new what it was called I could just google how it works. i keep getting error Call to undefined function codeandurl() below is my code PHP Code: <?php $value= strip_tags(get_field('link',$post)); $resultid=get_field('resultid',$post); codeandurl($resultid,$value); ?> <div id="result"></div> <script type="text/javascript"> function codeandurl(resultid,url){ $( "#result" ).text(resultid); $( "#result" ).dialog({ modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); window.open(url); return false; } </script> I found this script, and it works great: Code: <script type="text/javascript">
function disable(element)
{
var input = document.getElementById(element).getElementsByTagName("input");
for(var i = 0; i < input.length; i++)
{
input[i].setAttribute("disabled","true");
}
}
</script>
I tried to make the inverse by simply reversing the setAttribute() like so: Code: <script type="text/javascript">
function enable(element)
{
var input = document.getElementById(element).getElementsByTagName("input");
for(var i = 0; i < input.length; i++)
{
input[i].setAttribute("disabled","false");
}
}
</script>
But that didn't do it. Can someone show me why, and how to fix it? Here's the sample form which I'm trying to test it on: Code: <form>
<input type="radio" name="test" onclick="disable('D1')" /> disable<br/>
<input type="radio" name="test" onclick="enable('D1')" /> enable<br/>
<fieldset id="D1">
<input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" /><br/>
<input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" /><br/>
<input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" /><br/>
</fieldset>
</form>
Edit: The ultimate goal which I'm working toward now (step by step =) is to have a form more like: Code: <form>
<input type="radio" name="test" onclick="disable('D1')" />
<fieldset id="D1">
<input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" />
</fieldset>
<input type="radio" name="test" onclick="disable('D2')" />
<fieldset id="D2">
<input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" />
</fieldset>
<input type="radio" name="test" onclick="disable('D3')" />
<fieldset id="D3">
<input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" />
</fieldset>
</form>
And have the fieldsets enable and disable according the selection of the radio buttons. Also, the fieldsets (and their ID's) will be dynamically generated via PHP Thanks-a-bunch, ~ Mo Hi All, I'm trying to convert an anonymous function to a real function (nesting is getting out of hand), however the msg object becomes undefined after conversion.

I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe. Link to the page: Franklin Township Soccer Club - Change Field Status My sad, sorry attempt =| Code: $( "li.open" ).click(function() {
$( this ).toggleClass( "closed" );
});
$( "li.closed" ).click(function() {
$( this ).toggleClass( "open" );
});
The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so! In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission! I do appreciate any help given! Dave Code: <html>

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic. Now for the problem: When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page". I don't know if there is a better way to go about this, but as for this route, I am stuck. Any help is greatly appreciated! -Shane I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE). The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden. However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case. Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed? Hi, Any one help me In one variable i have some data ex: var data = document.getElementById("imageId").value; I want to pass this data to another function inside another function ex: var button1 = '<img src="images/Remove-button.gif" width="70" height="15" onclick="removeVerifyImageRow(this),saveLibData('+data+')"/>'; while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'. this is very urgent to solve this problem plz any one help me 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 Thank you in advance if someone can help. I have been banging my head against the wall for hours now. Here is the code: Code: for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {
value: BS_crm['activityTypes'][i]['id'],
label: "Add New "+BS_crm['activityTypes'][i]['label'],
css: BS_crm['activityTypes'][i]['css']+"_16",
onClick: clickFunc
};
previewLinks.items.push( type );
}
Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to: Code: var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };
then everything would work as I need. How can I make this happen? I would really appreciate any help. Thank you again in advance. How can I call a PHP Function inside a Javascript Function? 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> Hi, I am working on a google map where you can show lines on the map by checking checkboxes. Lines are displayed according to their category attribute in the xml file. The function that picks up the checkbox click is like this: Code: function boxclick(box,category) {
if (box.checked) {
show(category);
} else {
hide(category);
}
Another part of the code assigns that category attribute to arrows, so that when a line of "x" category is displayed, the relevant arrows are displayed along with it, to indicate directionality. I also have a select list which displays the lines by looping through their array and using selectedIndex in a function called handleSelected2. But I can't get the arrows to display along with the lines from the select box. After trying many, many things, I figure that all I need to do is to call the show(category) function from inside the handleSelected2 function and it should all come together. So I came up with this: Code: function handleSelected2(opt,category) {
for (var h = 0; h <gpolylines.length; h++) {
gpolylines[h].hide();
}
h = opt.selectedIndex - 1;
if (h > -1) {
gpolylines[h].show();
}
for (var v=0; v<pts.length; v++) {
show(category);
}
}
which gets me lines, but no arrows. You can see it sort of working he http://www.xelawho.com/map/zonesarrowstest.htm I figure I've got to be close, because if I just tell it to show all the arrows (without going through the category filter) like this: Code: function handleSelected2(opt,category) {
for (var h = 0; h <gpolylines.length; h++) {
gpolylines[h].hide();
}
var h = opt.selectedIndex - 1;
if (h > -1) {
gpolylines[h].show();
}
for (var i=0; i<pts.length; i++) {
pts[i].show();
}
}
then all the arrows show up, as you can see he http://www.xelawho.com/map/zonesarrowstest2.htm I'm not getting any error messages and I've tried pretty much everything I can think of... I've been tweaking this for days and it's driving me crazy. Does anybody else have any ideas? Thanks in advance. 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. Hello again! Is there any way to pass a function(with its parameters) to another function using a parameter? Examples: Here is how I do it now: PHP Code: function output(text){ alert(text); } function bla(text, func){ output(text); } bla("Text is here", output) //Outputs "Text is here" I only want to pass the function to bla() as a parameter. I need something like this: PHP Code: function output(text){ alert(text); } function bla(func){ output(); } bla(output("Text is here")) //Outputs "Text is here" Is this possible in some way? Thanks in advance. |
