How can I clear all the text boxes of a div from client side, in which the parent not contains any from tags.?
Thanks
If you put a classname on the divs:
var nodes = dojo.query(".className");
for(var x = 0; x < nodes.length; x++)
{
nodes[x].value = "";
// nodes[x].innerHMTL = "";
}
Or you may get the nodes with somethign like this:
var nodes = dojo.query("div>input[type='text']");
(I did not test :-/)
Adding on unludo's answer (and if using dojo 1.7):
require(["dojo/query"], function(query){
query("div > input[type='text']").forEach(function(node){
node.value = "";
});
});
if dojo < 1.7
dojo.query("div > input[type='text']").forEach(function(node){
node.value = "";
});

I’m new to both Ionic and Vue.js. I’m taking advantage of this summer break to start learning both.
I’m building a mobile app for this purpose and so far, so good. However, I have found and issue that I hope you could help me with. Namely, how to fetch or “call” data from one file to another (Is it called routing?).
In my app, I am trying to start/open a function named myFunction() from one of the pages (quiz.vue) when I call it using v-on:click="myFunction3".
This function is located in a JS file called quizz.js, and it is located in the assets folder. This is its path: (“./assets/js/quizz.js”).
I have tried many things to make it work and finally it is working as it should. However, I think my solution is not optimal as it keeps throwing “Uncaught TypeErrors” in the console of the Developer’s Tool…even though it works.
My solution was to push the function inside methods: this.$router.push(myFunction3())
Also, when running the app, it says that myFunction() , and other functions in the same quizz.js file, “is define but never used”.
If you could advise me with anything, I would be most grateful. I am still a beginner so please explain it to me in as simple a manner as possible.
methods:{
openMenu(){
menuController.open("app-menu")
},
myFunction3(){
this.$router.push(myFunction3())
},
Below, the quizz.js file:
var mlhttp = new XMLHttpRequest();
mlhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var myObj = JSON.parse(this.responseText);
const quiz = myObj.results[0]['question'];
const correctAnswer = myObj.results[0]['correct_answer'];
const incorrect = myObj.results[0]['incorrect_answers'];
incorrect.push(correctAnswer);
shuffle(incorrect);
document.getElementById("ans").innerHTML = quiz;
var text = "";
var val = 0;
var i;
for (i = 0; i < incorrect.length; i++) {
if(incorrect[i] == correctAnswer){
text += "<ion-button fill='outline' id='right' onClick='increment();myFunc();'/><b>" + incorrect[i] + "</b></ion-button></br>";
val = val + 1;
}else{
text += "<ion-button fill='outline' class='wrong' onClick='myFunc2();'/><b>" + incorrect[i] + "</b></ion-button></br>";
}
}
document.getElementById("ans5").innerHTML = text;
}
};
var j=0;
function myFunction3() {
document.getElementById("ans6").innerHTML = "";
mlhttp.open("GET", "https://opentdb.com/api.php?amount=1", true);
mlhttp.send();
j++;
document.getElementById('ans11').innerHTML=j;
}
function shuffle(array) {
for (let i = array.length - 1; i > 0; i--) {
let j = Math.floor(Math.random() * (i + 1));
[array[i], array[j]] = [array[j], array[i]];
}
}
function myFunc(){
document.getElementById("ans6").innerHTML = "<h1 style='color:green'><i class='fa fa-check'></i> That is correct!</h1>";
document.getElementById("right").style.color = "white";
document.getElementById("right").style.backgroundColor = "green";
var audio = new Audio('./assets/sound/win.mp3');
audio.play();
}
function myFunc2(){
document.getElementById("ans6").innerHTML = "<h1 style='color:red'><i class='fa fa-thumbs-down' ></i>Wrong Answer! </h1>";
document.getElementById("right").style.color = "white";
document.getElementById("right").style.backgroundColor = "green";
var x = document.getElementsByClassName("wrong");
var i;
for (i = 0; i < x.length; i++) {
x[i].style.backgroundColor = "rgba(255, 0, 0, 0.8)";
x[i].style.color = "white";
}
//document.getElementById("wrong").style.color = "red";
var audio = new Audio('./assets/sound/wrong.mp3');
audio.play();
}
var i=0;
function increment() {
i++;
document.getElementById('ans10').innerHTML=i;

I have a bootstrap tabs that is working well.
I have an area map that is working well if it is not inserted into a tab.
I use the Responsive Image Maps jQuery Plugin from Matt Stow, also works fine.
The symptom:
Then I put the area map into one of the tabs, a not active by default.
Then I click on the tab to make it shown. So the img is well shown.
But the area map does not working. I can't see the clickable rect.
But if I manually resize my navigator, then the area map works.
The page: https://boutique.bilp.fr/71-les-pieds-de-poteaux.html
Select tab "Guide de choix", the white rectangles should be clickable. THey are not until I manually resize the window.
The cause:
The responsible is the Responsive Image Maps jQuery Plugin. In its code, it makes a call to the jquery .width() method to obtain the width of the img where the map should works. And because the parent (tab) is hidden, the returned width is wrong. And it uses it to resize the map... with bad values. The map is then so small that it seems to not work.
Thanks for your help.
One solution is to modify the Responsive Image Maps jQuery Plugin by making ancestors visible before calling width().

I will propose this improvment to Matt Stow, the author
I have a problem getting my mind round variable scope and could do with some help :)
I'm setting up a module in joomla that will rotate images. I've a bit of code I've used on non Joomla sites that works fine. However I've ported it and I'm running into problems that I think are variable scope issues so any thoughts would be great.
Sorry for the long code but I included the whole function in case (when it works) it might help someone else.
function slideshow(container,containerCaption,previewCode,timer,classis,headerId,thumbOpacity,titlebar){
var showDuration = timer;
var container = $(container);
var images = $(container).getElements('span');
var currentIndex = 0;
var interval;
var preview = new Element('div',{
id: containerCaption,
styles: {
opacity: thumbOpacity
}
}).inject(container);
preview.set('html',previewCode);
images.each(function(img,i){
if(i > 0) {
img.set('opacity',0);
}
});
var show = function() {
images[currentIndex].fade('out');
images[currentIndex = currentIndex < images.length - 1 ? currentIndex+1 : 0].fade('in');
var title = '';
var captionText = '';
if(images[currentIndex].get('alt')) {
cap = images[currentIndex].get('alt').split('::');
title = cap[0];
captionText = cap[1];
urltoUse = cap[2];
preview.set('html','<span class="lctf1"><ahref="'+urltoUse+'">'
+ title + '</a></span>'
+ (captionText ? '<p>' + captionText + '</p>' : ''));
}
};
window.addEvent('domready',function(){
interval = show.periodical(showDuration);
});
}
window.addEvent('domready',function() {
container = "slideshow-container";
containerCaption ="slideshow-container-caption";
previewCode = '<span ><?php echo $itemtitle[0];?></span><p ><?php echo $itemdesc[0];?></p>';
timer = <?php echo $slidetime*1000;?>;
classis = 1;
headerId = "";
thumbOpacity =0.7;
titlebar = "<?php echo $showTitle;?>";
if($(container)){
slideshow(container,containerCaption,previewCode,timer,classis,headerId,thumbOpacity,titlebar);
}
});
The javascript error being thrown is that preview is undefined.
Your code seems to work, I made a jsfiddle here: http://jsfiddle.net/7E2MX/3/ which runs with no errors.
I did change one line though:
var images = $(container).getElements('span');
to
var images = $(container).getElements('img');
The home page on my app has a swipable carousel
`{
xtype : 'carousel',
id:'myCar',
autoDestroy:false,
styleHtmlContent:true,
padding:'0 0 0 0',
height:100
}`
I have a painted listener function on my view which add items to my carousel dynamically.
`var store = Ext.getStore("inspirationStore");
var car = Ext.getCmp('myCar');
var items = car.getItems();
//destroy all items within this container before populating
if (items.length > 1){
for (var j = 0; j < items.length; j++){
items[j].destroy();
}
}
for (var i = 0; i < store.getCount(); i++){
var item = Ext.create('Ext.Panel',{
html:'<p class = "inspirationMessage"><b>'+ store.getAt(i).data.message + '</b></p>' + '<p class = "authorName"><b>' + store.getAt(i).raw.Author__r.Name + '</b></p>',
cls:'carouselPanel'
});
car.add(item);
}`
The carousel works fine the first time ,But when I go To another page then come back to my home page my carousel doesnt swipe. I could see that items are added but the carousel is not working the way it should. Any suggestions?
use setItems( Array/Object items ) which
Sets the value of items.
docs
Instead of adding items in loop try this:
var items = [];
for (var i = 0; i < store.getCount(); i++){
var item = Ext.create('Ext.Panel',{
html:'<p class = "inspirationMessage"><b>'+
store.getAt(i).data.message + '</b></p>' +
'<p class = "authorName"><b>' +
store.getAt(i).raw.Author__r.Name + '</b></p>',
cls:'carouselPanel'
});
items.push(item);
}
car.add(items);
Using SlickGrid to display some pretty elaborate grids. The Example I am showing here isn't my code but basically an example given by the SlickGrid people duplicating my issue. My Grids need to have columns added dynamically with the column names being fed through an AJAX feed. Creating the column object in JS is not a problem and even adding them using the .push is seems to work fine as I can see them in the firebug console. The new columns never seem to rendner. I get a a bunch of tiny empty cells at the end of the grid but they never populate.
The script below can be replaced with the script in the "example1-simple.html" viewed here.
<script src="../lib/jquery.jsonp-1.1.0.min.js"></script>
<script>
var grid;
var data = [];
var columns = [
{id:"title", name:"Title", field:"title"},
{id:"duration", name:"Duration", field:"duration"},
{id:"%", name:"% Complete", field:"percentComplete"},
{id:"start", name:"Start", field:"start"},
{id:"finish", name:"Finish", field:"finish"},
{id:"effort-driven", name:"Effort Driven", field:"effortDriven"}
];
var dynamicColumns = [];
var options = {
enableCellNavigation: true,
enableColumnReorder: false
};
$(function() {
data = [];
BuildExtraColumnsAJAX();
for (var i = 0; i < 2000; i++) {
data[i] = {
title: "Task " + i,
duration: "5 days",
percentComplete: Math.round(Math.random() * 100),
start: "01/01/2009",
finish: "01/05/2009",
effortDriven: (i % 5 == 0)
};
for (var x = 0; x < 20; x++) {
var columnName = "dynamicColumn" + x;
data[i][columnName] = x;
}
}
//alert("Go Pack Go");
grid = new Slick.Grid("#myGrid", data, dynamicColumns, options);
$("#myGrid").show();
})
function BuildExtraColumnsAJAX(){
//dynamicColumns = [];
for (var x = 0; x < columns.length; x++){
dynamicColumns.push(columns[x]);
}
var url = "http://services.digg.com/search/stories? query=apple&callback=C&offset=0&count=20&appkey=http://slickgrid.googlecode.com&type=javascript";
$.jsonp({
url: url,
callbackParameter: "callback",
cache: true, // Digg doesn't accept the autogenerated cachebuster param
success: onSuccess,
error: function(){
alert("BOOM Goes my world");
}
});
}
function onSuccess(resp) {
for (var i = 0; i < resp.stories.length; i++) {
dynamicColumns.push( {
id: "dynamicColumn" + i,
name: "Dynamic Column" + i,
field: "dynamicColumn" + i
});
}
}
function BuildExtraColumns(){
dynamicColumns = [];
for (var x = 0; x < columns.length; x++){
dynamicColumns.push(columns[x]);
}
for (var i = 0; i < 20; i++) {
dynamicColumns.push( {
id: "dynamicColumn" + i,
name: "Dynamic Column" + i,
field: "dynamicColumn" + i
});
}
}
If I put the line grid = new Slick.Grid("#myGrid", data, dynamicColumns, options); in the firebug console and run it the grid than renders fine. It is almost like the script is still executing lines of code even though its not done creating the dynamicColumns.
The Digg AJAX call is just to similute an AJAX call, I of course would be using my own.
The grid is getting initialized before the AJAX call to get the additional columns completes.
Either wait until the columns have loaded to initialize the grid, or update the grid after the additional columns have loaded:
grid.setColumns(dynamicColumns);
