JavaScript - Sencha Nested List?
here is my function at the moment which gets some HTML:
Code: function showRecent() {
Ext.Ajax.request({
url: 'server.php?action=get',
success: function(e) {
var obj = Ext.util.JSON.decode(e.responseText);
var pubs = obj.pubs;
if (pubs) {
var html = tpl.applyTemplate(pubs);
Ext.getCmp('recentTab').update(html);
}
}
});
}
here is my HTML: Code: <div id="pubs" class="x-hidden-display">
<tpl for=".">
<div class="detail">
<div class="clear">
<span class="span2 bottomright">{rsTown}</span>
</div>
<div class="clear"></div>
</div>
</tpl>
<br/>
<br/>
<br/>
</div>
I'd like to show my data in a nested group list Please help?! Similar TutorialsI'd be grateful for any help please. I've just started to build my first ever sencha app and am pleased with the results so far, but am now stuck on one thing. I've built a search form and want to be able to display the results on the same page, but this is where I'm stuck. The form works and sends the results using GET, but it doesn't send it to the correct place. I want to show it on the same page (I've built a php file called search.php to handle the results), but it reloads the whole app with the variables in the url. I've tested all of the code away from the app and it works perfectly so I know the problem isn't with the code, but more with my lack of understanding of Sencha so would be extremely grateful for any help. Code: searchForms = new Ext.TabPanel({
fullscreen: true,
title: 'Search',
displayField: 'text',
sto searchForm,
iconCls: 'search',
items: [{
id: 'searchSubmit',
xtype: 'form',
standardSubmit : true,
scroll: 'vertical',
items: [{
xtype: 'fieldset',
title: 'Keywords',
defaults: {
// labelAlign: 'right'
labelWidth: '35%'
},
items: [{
xtype: 'textfield',
name: 'keywords',
id: 'keywords',
placeHolder: 'EG: Music, TV',
autoCapitalize : true,
required: true,
useClearIcon: true
}]
}, {
xtype: 'fieldset',
title: 'Advanced Search',
items: [{
xtype: 'selectfield',
name: 'genre',
id: 'genre',
label: 'Genre',
options: [{
text: 'All',
value: ' '
text: 'Country',
value: '1'
text: 'Sci-Fi',
value: '2'
text: 'Western',
value: '3'
}]
}, {
xtype: 'selectfield',
name: 'media',
id: 'media',
label: 'Media',
options: [{
text: 'All',
value: ' '
text: 'Music',
value: '1'
text: 'TV',
value: '2'
text: 'Movie',
value: '3'
}]
}]
}, {
layout: 'vbox',
defaults: {xtype: 'button', flex: 1, style: 'margin: .5em;'},
items: [{
text: 'Search',
ui: 'confirm',
scope: this,
hasDisabled: false,
handler: function(){
searchForms.submit({
url: 'search.php'
});
}
}, {
text: 'Reset',
ui: 'decline',
handler: function(){
searchForms.reset();
}
}]
}]
}]
});
I've then tried to use this to display the results on the same page, but as I say this just doesn't work. It doesn't call the search.php page at all. I've made sure all of the files (except the index.js file which is in a js folder) are in the same directory as the index.html file. I've also tried to load the file in the app seperately by using: Code:
Ext.regModel('mobile', {
fields: [
{name: 'text', type: 'string'}
]
});
var searchForm = new Ext.data.TreeStore({
model: 'mobile',
proxy: {
type: 'ajax',
url: 'search.php?keywords=test',
reader: {
type: 'tree',
root: 'items'
}
}
});
and that works perfectly so I know that all of the php stuff is working and does work with Sencha Touch, but I'm just not sure how to get it to only work when somebody clicks 'search' I'd be grateful for any help with this as I've spent days searching the web to get this fix, but nothing seems to be working I don't know if this is of help, but the main javascript file is: Code: var tabPanel;
var homePanel = new Ext.Panel({

i am new to sencha touch,and i created a login form which accepts user id and password and a login button,so when i click on login button i should get the user id value as a alert.and the code is Code: Ext.setup ({
onReady: function () {
var myform=new Ext.form.FormPanel({
id:'form',
fullscreen:true,
standardSubmit:true,
dockedItems:[{
Dock:'top',
xtype:'toolbar',
height:40,

id:'login',
}
],
items:[{
xtype:'textfield',

label:'Password'
},
{
xtype:'button',
ui:'round',
width:'50%',
text:'Login',
align:'center',
handler:function()
{
gettingvalues();/* var fields = form.getValues();
console.log(fields['name']); */
}
}
],
});
gettingvalues=function()
{
var fields=myform.getValues();
Ext.Msg.alert(fields['id'].getValue());
}

But am not getting any value in alert,what i have to do. and after that i want to send those values to our local server which requires id and password,it will be in the format of... oururl?action=login&id=xyz&pwd=xyz, in this it will accepts and returns the response,so for that what i have to write, please let me know as soon as possible. Thanks in advance. Hi all, I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County). I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database. This piece of code is working well . . . . Code: <?php
$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error());
mysql_select_db('mydatabase') or die('Could not select database');
if(isset($_GET["County"]) && is_numeric($_GET["County"]))
{
$County = $_GET["County"];
}
if(isset($_GET["Region"]) && is_numeric($_GET["Region"]))
{
$Region = $_GET["Region"];
}
?>
<script language="JavaScript">
function autoSubmit()
{
var formObject = document.forms['theForm'];
formObject.submit();
}
</script>
<form name="theForm" method="get">
<!-- County SELECTION BASED ON city VALUE -->
<?php
?>
<select name="County" onChange="autoSubmit();">
<option value=''</option>
<?php
//POPULATE DROP DOWN MENU WITH COUNTRIES FROM A GIVEN city
$sql = "SELECT * FROM county_regions";
$counties = mysql_query($sql,$link);
while($row = mysql_fetch_array($counties))
{
echo ("<option value=\"$row[CountyID]\" " . ($County == $row["CountyID"]? " selected" : "") . ">$row[County]</option>");
}
?>
</select>
<?php
?>
<br><br>
<?php
if($County!= null && is_numeric($County))
{
?>
<select name="Region" onChange="autoSubmit();">
<?php
//POPULATE DROP DOWN MENU WITH RegionS FROM A GIVEN city, County
$sql = "SELECT * FROM county_regions WHERE CountyID = $County ";
$Regions = mysql_query($sql,$link);
while($row = mysql_fetch_array($Regions))
{
echo ("<option value=\"$row[CountyID]\" " . ($Region == $row["CountyID"]? " selected" : "") . ">$row[Region]</option>");
}
?>
</select>
<?php
}
?>

It's probably obvious to you guys!! Thanks in advance for your help. 09-01-10 Not sure exactly where to post this thread as it involves HTML, Javascript and embedded media players. It probably would be more appropriate here as there is much Javascript involved.... Hello, I am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see: http://codingforums.com/showthread.php?t=50666 I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below: 1. How can I have the Jukebox cycle through all tunes and then start over from the beginning? 2. How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the user’s selection and then play all songs to the end. Then as in #1, start over from the beginning? Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a “playlist” from the drop down. Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to. The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist. Go to url removed and click on the link that says: “Media Player Using an .M3U Playlist” Jukebox utilizing an .m3u playlist: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

Here is the .m3u playlist for the above code: Code: #EXTM3U #EXTINF:Bill Evans - G Waltz media/G Waltz.mp3 #EXTINF:Dan Pincus - In Your Time media/In Your Time.mp3 The following code is for the Jukebox that has a list of links in a dropdown list. If I go with this idea, I would like for the list not to be a dropdown list but just a list of tunes. The user should be able to click on any tune in the list and the player should start from that point, play all the remaining tunes in the list and then start from the beginning.

Another idea I found on the WEB also uses an .m3u playlist. The good thing about it is that it lists all the tunes in the playlist which the user can then select from. This jukebox calls up an entire Windows Media Player. If I was to use this idea I would like to be able to disable the left side of the player where the user has options such as burning to CD, Media Guide, Radio Tuner etc… Go to url removed and click on the link that says: “Media Player Within an IFrame Using .m3u Playlist”” Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>JukeBox</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="Expires" content="-1"> </head> <body> <IFRAME name="frame" src="JukeboxList.m3u" width="100%" height="347" scrolling="no" frameborder="0"> [Your user agent does not support frames or is currently configured not to display frames.] </IFRAME> </body> </html> Thanks! Dan I would like to make an ordered list, for example: 1. Airplane 2. Boat 3. Car I'd like one of the words to be displayed on my webpage, for example: Boat Then I'd want an up button, and a down button. The up button would display Airplane instead of Boat, and the down button would display Car instead of Boat. Once it got to Car, the same up button would change it back to boat. How do I do this? Thanks. I have two lists/menus that are start and end times and I want to make the end time list/menu advance 2 hours from whatever is chosen in start list/menu.

[ICODE] You can find this at http://www.crazywayno.com/2fields.php Thanks Hey Guys, I'm currently a seasoned programmer who is in a programming class at my school. We're currently learning advanced JavaScript, and we're on the topic of nested loops. After teaching us about for and while loops, my teacher gave us a little puzzle to solve. It's kind of difficult to explain, but I'll give you guys my current code and what it outputs. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>Word Reversal</title>
<script type="text/javascript">
var ask = prompt("How many words do you want?","");
while (ask < "1")
{
alert("You have to have at least one word!");
var ask = prompt("How many words do you want?","");
}
var num = parseInt(ask) + 1;
var final = "";
for (var i=1; i < num; i++)
{
var word = prompt("What's word " + i + "?");
final = final + "Word " + i +": " + word + "<br/>";
}
</script>
</head>
<body>
<script type="text/javascript">
document.writeln(final);
</script>
</body>
</html>
The current output, when the user wants two words, and word 1 is one and word 2 is two, comes out to be: Code: Word 1: one Word 2: two Which is great, but the only problem is, this is what the output's supposed to be: Code: Word 2: two Word 1: one I'm stumped. I've had numerous programming challenges in my life which I've solved, but I'm not sure where to go next on this one. The script is supposed to use a nested loop, but what goes in what loop to reverse the order of the user's input? I asked my teacher for help, but he told me "Ask someone else." I asked another seasoned programmer in my class, who was just about as stumped as I was, so I went back to my teacher. "Well, ask another person" he replied. And can you believe this guy has a Master's Degree of Computer Science? So I'm asking you guys: the community. I hope someone will be able to help me. On top of that, I have to help and tutor two special education students in my class on this kind of stuff during class, and they can't get the project done until I get it done, as they learn from analyzing and copying my work (which my teacher told me to do). They get upset when they have nothing to code, and they end up goofing off the entire period, or using it as a study hall. I need to get them back on track, so we can move on to the next project. Please help me with this code - it would be greatly appreciated. Thank you! Hi I need help to finish this code with using nested if statements A price of a ticket to a passenger will be: First Class 500 Economy Class (with meal) 400 Economy Class (without meal) 200 How I can write a JavaScript code according to the following specifications: a. Read the class that the passenger wants to travel on. b. If the class is the first class, print the price of ticket. c. If the class is the economy class, ask the user if he/she wants a meal on the flight. Then print the price of the ticket according to the response of the passenger. The program should simply accept one possible strings the user enters; it is not required to work for all possible inputs such as First, first, FIRST or Yes , yes, YES. This is the code which I have been trying { var inputNum = prompt("Enter the class you want\n first class?\neconomy? :"); if (isNaN(inputNum)) { if (inputNum.match(/first class/)) { document.write("<h1><center>your Ticket is 500<\center><\h1>"); } else { prompt("<h1>if you want a meal on the flight press OK <\h1>"); document.write("<h1>your ticket is 400<h1>,"); } } OK i'm trying to make an affiliate section for my page in javascript, I used double arrays and it's terribly coded.

Hello. I was wondering if there is a way to call a second Javascript function from within the first. For example: <script>...call first function...</script> Inside first function: If (a==1) <script>...call second function...</script> else (a==2) <script>...call third function...</script> My thinking as to why I would need this is because I need to access two different Google Maps API codes. If that isn't possible, does anyone have any other suggestions? Hello codingforums.com! Right, this is probably going but such a stupid newbie thread but here goes.. I've finally got myself into gear to start learning javascript. I've been watching video tutorials, learning from websites and simply learning by error. I understand the concept of for loops, but the whole nested thing doesn't seem to click for some reason. I thought i understood and managed to write a piece of code that constantly writes '*' across the screen. Could someone with some pretty damn good knowledge of javascript be able to walk me through step by step of my script to explain what actually is happening? It would help loads. here is the script, many thanks!! <script type="text/javascript"> var counter = 0; function writeStars(){ for(i=0;i<1;i++){ for(a=0;a<=counter;a++){ document.write("*"); } counter++ document.write("<br />"); } } setInterval("writeStars()", 200); </script> I'm trying to reuse some code in a different context to do a different job. The code to be reused contains hundreds of lines similar to a = new b.c.d(e,f) with different value for e and f. I need to create a new user defined object with the structure b.c.d. I've made numerous attempts along the lines of: Code: function d (e, f) {
this.e = e;
this.f = f;
}
function c () {
this.d = d (e, f);
}
function b () {
this.c = c;
}
var a = new b.c.d("test", "message");
with various permuations of functional declarations. However I get error message "Object expected" or "b.c.d is null or not an object" at the final line of the example. It works with the test line var a = new d("test", "message") but not when I start to build up the expression. How should I define of b.c.d? This may be a basic programing problem but I am writing a function to validate a form using a bunch of else-if statements and encounters a problem when I use nested if/else-if statements. It will not continue on to the next else-if, after it returns false. Code: // to check each entry on the form and alert user if entry is invalid.
function checkform(){
var checkssn = /(\d{3})-(\d{2})-(\d{4})/;
var checkphone = /(\d{3})-(\d{4})/;
var checkname = /[a-zA-Z]+(\.|,|\s)*/;
var checkzip = /(^967|^968)\d{2}(-\d{4})?$/;
// check to see if user have selected an Election
if (!document.f1.elections[0].checked && !document.f1.elections[1].checked && !document.f1.elections[2].checked && !document.f1.elections[3].checked) {
window.alert("Please select an Election!")
return false;
// check to see if user entered a valid SSN
} else if ( checkssn.test(document.f1.ssn.value) == false){
window.alert("[1]. Please enter a valid social security number in the format ddd-dd-ddd");
return false;
// check to see if user entered a valid home telephone number or business telephone number
}else if ( document.f1.home_phone.value == '' && document.f1.business_phone.value == '') {
window.alert("[4]. Please enter a Home or Business telephone number!")
return false;
} else if ( document.f1.home_phone.value != ''){
if (checkphone.test(document.f1.home_phone.value) == false){
window.alert("[4]. Please enter a valid home phone number in the format ddd-ddd");
return false;
}
} else if ( document.f1.business_phone.value != ''){
if ( checkphone.test(document.f1.business_phone.value) == false){
window.alert("[4]. Please enter a valid business phone number in the format ddd-ddd");
return false;
}
// check to see if user entered a valid Name
}else if ( checkname.test(document.f1.lastname.value) == false){
window.alert("[5]. Last Name can only consist of letters, periods(.), commas(,) and spaces");
return false;
}else if ( checkname.test(document.f1.firstname.value) == false){
window.alert("[5]. First Name can only consist of letters, periods(.), commas(,) and spaces");
return false;
The problem occurs when it validates the phone numbers. When a valid number is entered, it will not move to the next else-if statement to validate the name. It's been years since I program in Java/C, so I'm a bit rusty. Any help is appreciated. -Alex Hi, I have two dropdown lists with the second one being dependent on the selection in the first. Options in list 1: 1,3 or 4 List two should be enabled when 3 or 4 is selected in list 1. So far so good, managed to get it to work with only one set of lists, but I actually have 18 of those sets in this form: Code: <select name="fw[$i]" id="fw[$i]"> <option value="1">FWH</option> <option value="3">links</option> <option value="4">rechts</option> <option value="0" selected></option> </select><br /> <select name="lie[$i]" id="lie[$i]" disabled="disabled" onchange="showBox($i,xxx);"> <option value="0" selected>---</option> <option value="1">gut</option> <option value="2">schlecht</option> <option value="3">Strafschlag</option> <option value="4">OB</option> </select> $i is my index generated by my PHP script and runs from 1 to 18. Everything works just fine as long as the index is not in play. With the index my function breaks, most probably due to my inability to extract the second parameter (xxx above) from the selection field. Here's my function, there could be something wrong there too with how exactly to specify the proper dropdown list to enable. Code: function showBox(field,val) {
if (val > 1) {
var box = 'lie[' + field + ']';
document.form1.box.disabled == false;
}
else {
document.form1.box.disabled == true;
}
}
Finally, I'm not that adept in javascript programming, more like a trial and error guy, how has hit the wall with this problem. Thanks in advance! Joe I have a nested if that is not working, well I have two which are pretty much the same code apart from one has more conditions. The one with the least does not work. It is basically a quick password checker to see if the typed password matches the previously typed and then display an image according. Code: function checkPass(id){
var pass = document.getElementById(id).value;
if(pass == "")
{
notValid(id);
}
else if(id == "pwd2" && pass !== document.getElementById("pass").value || document.getElementById("pass").value == "")
{
notValid(id);
}
else
{
isValid(id);
};
};
If it is blank it calls notvalid and if the second if flags it calls notvalid however if it is ok then it does not do the else. Any ideas?? Thanks. js code is as follows: Code: uniqueNo=(function(){
var no=0;
return function(){ return no++; }
})()
document.writeln(uniqueNo()); // 1st time call
document.writeln(uniqueNo()); // 2nd time call
document.writeln(uniqueNo()); // 3rd time call
the result is 1 2 3 why after the 2nd call, the declaration 'var no=0' is useless -- seems 'no' is updated and stored each time it is called? many thanks I'm having trouble getting this nested loop to work. It only outputs the last image and I want it to loop through the images. Code: function loadgallery (){
var picarray= new Array ()
picarray[0]="pic1.jpg"
picarray[1]="pic2.jpg"
picarray[2]="pic3.jpg"
picarray[3]="pic4.jpg"
picarray[4]="pic5.jpg"
picarray[5]="pic6.jpg"
for (j=0;j<picarray.length ;j++ ){
pic=picarray[j]
var tdarray = document.getElementsByTagName("td");
for (i=0;i<tdarray.length;i++ ){
tdarray[i].innerHTML='<select name="select1"><option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option><option value="5">5</option><option value="6">6</option></select><img src="pics/'+picarray[j]+'">';
}
}
}
window.onload=loadgallery;
Sorry folks, Im not sure that I am using the correct terminology here. What i would like to do is sort an array based on the [SortBy] value, however this array is nested. For instance: ar.[SortBy]"PartNumber" ar.[0].[PartNumber]"123" ar.[0].[PartName]"Widget1" ar.[1].[PartNumber]"345" ar.[1].[PartName]"Widget2" ar.[2].[PartNumber]"456" ar.[2].[PartName]"Widget3" ar.[3].[PartNumber]"567" ar.[3].[PartName]"Widget4" Thanks! |
