I have something that I can't understand and i'm struggling with that for 2 days.
For the story, I'm using VICOPO api to get zipcode/city (France only I think).
The thing is that the code I'm generating is not really good interpreted by jQuery (or maybe I'm doing it wrong)
Here is the code:
$('#postcode').val($('#postcode').val().toUpperCase());
if ($('#postcode').val().length == 5)
{
var $ville = $('#postcode');
$.vicopo($ville.val(), function (input, cities) {
if(input == $ville.val() && cities[0]) {
if (cities.length == 1)
$('#city').val(cities[0].city);
else
{
var html = '';
html += '<div style=\'text-align:center\'>';
for (var i=0; i<cities.length; i++)
{
var v = cities[i].city;
// --- HERE IS MY PROBLEM ---
html += '<p onclick=\'alert(\'' + v + '\');\'>' + v + '</p>';
}
html += '</div>';
console.log(html);
$('#multi_ville').html(html);
}
}
});
When I inspect the elements in the multi_div this is what I get:
<p onclick="alert(" billey');'>BILLEY</p>
<p onclick="alert(" flagey-les-auxonne');'>FLAGEY-LES-AUXONNE</p>
etc ....
And when I inspect the console log, all looks correct:
<p onclick='alert('BILLEY');'>BILLEY</p>
<p onclick='alert('FLAGEY-LES-AUXONNE');'>FLAGEY-LES-AUXONNE</p>
<p onclick='alert('VILLERS-LES-POTS');'>VILLERS-LES-POTS</p>
etc ....
If someone have an idea or what I'm doing wrong, it would cool.
(may I mention, this code is in a smarty tpl file surrounded with the {literal} tag)
Try to create self closed tags via jquery and then append them to #multi_ville, here is an example:
// create div element
var div = $('<div/>', {
'style' : 'text-align:center'
});
for (var i=0; i<cities.length; i++)
{
var v = cities[i].city;
// create p element with click event and then append it to div
$('<p/>').on('click', function() {
alert(v);
}).text(v).appendTo(div);
}
$('#multi_ville').append(div);
EDIT It seems that my code above always alert the last city when we click on a element, that's because alert takes the value that v variable has at the time it runs, to solve this we can use let statement:
let v = cities[i].city;
Or a function:
for (var i=0; i<cities.length; i++) {
var v = cities[i];
createPTag(v, div);
}
function createPTag(v, div) {
$('<p/>').on('click', function() {
alert(v);
}).text(v).appendTo(div);
}
Instead of
html += '<p onclick=\'alert(\'' + v + '\');\'>' + v + '</p>';
try this:
html += '<p onclick="alert(\'' + v + '\');">' + v + '</p>';
Here's some info on when and how to use double/single quotes.
EDIT:
Also, check the else on this if statement:
if (cities.length == 1)
You need a closing curly bracket (}) to close in the else. It should be added directly after this line:
$('#multi_ville').html(html);

I'm beginner in JS. But, after many hours, i'm really close to the wanted result.
I declare my JS Function in head part
function getPrice(price) {
var tabPrice = price.split("");
var html = "";
var virguleIndex = null;
for (var index = 0; index < tabPrice.length; ++index) {
var priceNumber = tabPrice[index];
if (priceNumber == ',') {
virguleIndex = index;
html += "<span class='p-c'>" + priceNumber + "</span>";
} else if (priceNumber == '-') {
html += "<span class='p-d'>" + priceNumber + "</span>";
} else if (index > virguleIndex && virguleIndex != null) {
html += "<span class='p-" + priceNumber + " p-small'>" + priceNumber + "</span>";
} else {
html += "<span class='p-" + priceNumber + "'>" + priceNumber + "</span>";
}
}
var div = document.getElementsByClassName('price');
div[0].innerHTML = html;
}
and my div in body part
<div class="price"></div>
I made some test - And my function getPrice works perflectly
https://image.noelshack.com/fichiers/2018/02/4/1515663887-functionwork.jpg
Some, the only fail (I think) is that the innerHTML don't work and don't write de var html content in div class price.
I haven't idea yet after many (many) hours of looking.
Can you help me ?
Thanks in advance,
Ludovic
By going through your image it is clear your DOM is not ready. So Please call your function inside this Block.
(function() {
// your page initialization code here
// the DOM will be available here
//Call Your function inside this block. it will work ex. getPrice("100");
})();
Some news (I worked on this few hours), I check for the dom charging. I tried (thank for you answer) the call function / transpose the code and the end / forcing the function after the dom loading (with document.addEventListener("DOMContentLoaded", function(event) {)
Console log still working. But my div still empty :/
Thanks again !
I would like new text, as it is fading in, to push the older text down instead of having new text appear after old text. Is this possible? Have been having a lot of difficulty figuring this out.
Here is the javascript:
var $el= $('.fader').map(function() {
return this;
}).get();
$el.forEach(function (eachdiv){
var text = $(eachdiv).text(),
words = text.split(".");
var html = "";
for (var i = 0; i < words.length; i++) {
html += "<span>" + words[i] + " </span>" + '<br/>';
$(eachdiv).html(html).children().hide().each(function(i){
return $(this).delay(i*200).fadeIn(200);
});
}
});
The solution does seem to involve the use of prepend, but I'm not sure where to place prepend within the code.
Try For loop like this instead of yours. Just Giving you an idea. give fadeIn effect as per your data arrives.
for (var i = 0; i < words.length; i++) {
html.prepend("<span>" + words[i] + " </span>" + '<br/>');
$(eachdiv).html(html).children().hide().each(function(i){
return $(this).fadeIn(200);
});
}
This seemed to work in the return line:
return $(this).delay(i*200).prependTo(eachdiv).fadeIn(200);
Thanks for introducing me to prepend, Sindhoor!
I have an object, X, and some code that creates a div and assigns id = X.ID. After the html is created, I assign the object to the div, like this:
document.getElementById(X.ID).XValue = X;
If I set a break after that statement, I can evaulate document.getElementById(X.ID).XValue and see all the properties of X.
While I was creating the html, I added onmouseup="MOUSE_UP(event)".
var aProp = {};
aProp.ThisValue = "This";
aProp.ThatValue = "That";
aProp.Id = 5;
var html = '<div id="' + aProp.Id + '"';
var func = 'MOUSE_UP';
html += ' onmouseup="' + func + '(event) ">';
html += '</div>';
document.getElementById("test").innerHTML += html;
document.getElementById(aProp.Id).XVALUE = aProp;
function MOUSE_UP(event) {
alert(event.currentTarget.XValue.ThisValue);
}
Now, when I set a break at MOUSE_UP, event.currentTarget is my div (event.currentTarget.id == X.ID), but event.currentTarget.XValue is undefined.
Why is XValue undefined here when it was defined earlier?
Looks like setting innerHTML of #test would wipe out all custom properties from its children. You can check this in the jsFiddle. When you'll run the fiddle as it is, you'll notice NewProp of #1 will become undefined after adding more content with test.innerHTML += ... If you log tabIndex instead of NewProp, you'll get the correct values.
This happens because += operator is just a shortcut for a statement like a = a + b, which can also be written a += b.
Basicly you create a string from the inner HTML of #test, then add another string to it, and finally replace the original innerHTML of #test with this new string. All previous elements in #test are replaced with new ones, which don't have the custom properties set.
When setting id property for an element, also id attribute is added to the HTML, hence they are a part of innerHTML of #test, and are added to the newly created HTML too.
If you use proper DOM manipulation instead of setting innerHTML, you'll get the results you want. The code below uses createElement() and appendChild() methods instead of setting innerHTML.
function myMouseUp(e) {
alert("at MouseUp " + e.currentTarget.NewProp.ThisValue);
}
function buildOneDiv(aProp) {
var html = document.createElement('div');
aProp.ThisValue = 'This is ' + aProp.id;
aProp.ThatValue = 'That is ' + aProp.id;
html.id = aProp.id;
html.addEventListener('mouseup', myMouseUp, false);
html.innerHTML = 'Test ' + aProp.id;
return html;
}
function buildDivs(x) {
var html = buildOneDiv(x);
document.getElementById("test").appendChild(html);
document.getElementById(x.id).NewProp = x;
}
window.onload = function () {
var aProp, i;
for (i = 1; i < 4; i++) {
aProp = {};
aProp.id = i;
buildDivs(aProp);
}
};
A live demo at jsFiddle.
This is not so much an answer as it is a clarification and a work-around.
Given this html
<div id="test"></div>
and this code
function myMouseUp(e) {
alert("at MouseUp " + e.currentTarget.NewProp.ThisValue);
}
function buildOneDiv(aProp) {
aProp.ThisValue = "This";
aProp.ThatValue = "That";
var html = '<div id="' + aProp.id + '"';
var func = 'myMouseUp';
html += ' onmouseup="' + func + '(event) ">';
html += 'Test ' + aProp.id + '</div>';
return html;
}
function buildDivs(x) {
var html = buildOneDiv(x);
document.getElementById("test").innerHTML += html;
document.getElementById( x.id ).NewProp = x;
}
window.onload = function () {
for (var i = 1; i < 4; i++) {
var aProp = {};
aProp.id = i;
buildDivs(aProp);
}
};
The end result is that only the LAST div whose onmouseup is defined will have a legitimate value for NewProp at myMouseUp. For each other div, this property is undefined. This is why I got some comments indicating that "It does work." It works for ONE, which is all I had in my example. (This is the clarification.)
My workaround is to add a global object to be an associative array and change two statements:
var myDivs = {}; // global
Replace
document.getElementById( x.id ).NewProp = x;
in buildDivs with
myDivs[x.id] = x;
and replace
alert("at MouseUp " + e.currentTarget.NewProp.ThisValue);
in myMouseUp with
alert(myDivs[e.currentTarget.id].ThisValue );.
I'd still like to know why the original approach doesn't work.
I want to know how I change all the pre tags inside a document...
I'm using this:
var preContent = document.getElementById('code').innerHTML;
but this only changes the content of 1 pre tag... the one with the ID 'code'.
If you can show me how i can change all the pre tags using JavaScript I appreciate
Here's all the code:
window.onload = function () {
var preContent = document.getElementById('code').innerHTML;
var codeLine = new Array();
var newContent = '<table width="100%" border="1" '
+ 'cellpadding="0" cellspacing="0" >';
codeLine = preContent.split('\n');
for (var i = 0; i < codeLine.length; i++) {
newContent = newContent + '<tr><td class="codeTab1" >'
+ i.toString() + '</td><td class="codeTab2">'
+ codeLine[i] + '</td></tr>';
}
newContent = newContent + '</table>';
document.getElementById('code').innerHTML = newContent;
}
PS: This is to make a look like a normal compiler with numbers before the line
PPS: Each pre tag will have a different content and I want the same script to change it (if possible).
You can use getElementsByTagName:
var preElements = document.getElementsByTagName('pre');
for(var i = 0; i < preElements.length; ++ i)
{
var element = preElements[i];
/* modify element.innerHTML here */
}
First problem in you code . No two elements in a document can have same id .
So you can change it easily with jquery . look at the code .
$('pre').html("what ever text you want to show ");
Or with javascript you can do like this :
var x = document.getElementsByTagName('pre');
for(var i = 0; i < x.length; ++ i)
{
x.innerHTML = "what ever text you want to show";
}
I have an HTML table which contains about 1000 rows and 26 columns. I am using this jQuery plugin to navigate between rows and make a selection.
My first problem is that the plugin is working fine, but—even using the latest version (0.6.1)—it's very slow when working with 1000 rows.
My second problem is that I want to create a JSON object representing the selected row from the table. I wrote a function that does this, but again it's too slow on such a big table. The following code works, but I want to optimise it:
$(document).bind("keyup", function(event) {
var jsonText = "";
var i = 0;
var td_size = $("tr.selected td").size();
jsonText += "{";
for (i = 0; i < td_size; i++) {
if (i < td_size - 1) {
if (i == 0) {
// Get link URL.
jsonText += "\"" + $("thead tr th").eq(i).text() + "\":\"" + $("tr.selected td").eq(i).find("a").attr("href") + "\",";
} else {
jsonText += "\"" + $("thead tr th").eq(i).text() + "\":\"" + $("tr.selected td").eq(i).text() + "\",";
}
}
else {
jsonText += "\"" + $("thead tr th").eq(i).text() + "\":\"" + $("tr.selected td").eq(i).text() + "\"";
}
}
jsonText += "}";
$('#content').html('').append(jsonText);
});
Any suggestions please?
One thing you can do is optimize your jQuery selectors to help the Sizzler work faster...
instead of biding on keyup of all document, how about keyup of a specific tr?
$("tr.selected td").size(); // slow
$("table").find(".selected").find("td"); // probably faster
Save the selected tr outside the loop, you're asking the sizzler to find your object 26 times by looping 1000 rows!
$("thead tr th").eq(i) // on every loop element? slow, try saving the information before the keyup event, they are not going anywhere are they?
So probably something like this would be faster:
var $allTrs = $("tr");
var $allHeads = $("thead tr th");
$allTrs.bind("keyup", function(event) {
var jsonText = "";
var i = 0;
var $t = $(this),
$alltds = $t.find("td"),
td_size = $alltds.length();
jsonText += "{";
$.each($alltds, function(i){
jsonText += "\"" + $allHeads.eq(i).text() + "\":\"";
if (i == 0){ // you have a strange condition, will leave it up to u
// append link
jsonText += $(this).find("a").attr("href"); // i remove "" for better readability
}else{
// append text
jsonText += $(this).text();
}
});
jsonText += "}";
$('#content').text(jsonText); // cheaper than html
});
I have not tested this yet.
You can also create a json object directly (wouldn't affect how fast though), like this
var mynewjson = {};
Then inside a loop:
mynewjson[name] = value;
