I have a little problem here. ¿How i can manipulate a dynamically generated html, in Jquery?
I have a function like:
generatesomething : function(DestinationID,data){
result = $.DoSomething(data)
$('#'+Destinationid).html(data);
}
The script, in other point, receive through ajax an array. Naturally, I will iterate the array like:
$.each(response, function(key, value){
ThisHtml = '<div id="div'+key'"></div>';
$('#MyPlaceHolderDiv').html(ThisHTML)
//In this point, i really need to call my first function
$.generatesomething('div'+key',data)
//But not works!!!!
}
How i can manipulated the generated div using my function?
Thanks in advance!
Edit: in a try to clarify my question, i will paste the exact functions.
I made this function. Please do not laugh at my code, I am newbie in jquery.
jQuery.fn.extend({
/funciones Generales/
piegraph : function(GraficoDestino,tipo,arrayDatos,dato1,dato2,tooltiptemplate,labeltemplate){
var dataPoints = [];
$.each(arrayDatos, function(key, value){
var temporal = {};
temporal.label = value[dato1];
temporal.y = parseInt(value[dato2]);
dataPoints.push(temporal);
});
var opciones = {
animationEnabled : true,
data : [{
type : tipo,
startAngle : 0,
toolTipContent : tooltiptemplate,
indexLabel : labeltemplate,
dataPoints : dataPoints,
}]
};
$('#' + GraficoDestino).CanvasJSChart(opciones);
}
This function works pretty well... if i can give it the destination div to it.
In other part of my script, i have a ajax call:
Generadisco: function(){
var datos = {
"accion":"generadisco"
};
$.ajax({
type: "POST",
url: "blahblah.php",
data: datos,
dataType: "json",
success:function(response){
$.each(response, function(key, value){
esteHTML = '<div id="divdisco'+key+'"></div>
$('#discosplace').append(estehtml);
//the div is generated... but when i do...:
$(this).piegraph('divdisco'+key,'pie', response[3],0,1, "{label} #percent%","{label} ");
//nothing happens
});
}
});
}
I found some error in your code:
$('#MyPlaceHolderDiv').html(ThisHTML)
$.generatesomething('div'+ key ,data)
must to be:
$('#MyPlaceHolderDiv').html(ThisHTML);
$.generatesomething('div'+key',data);
Also try to add console.log(DestinationID) in first line of your function to see passed argument (DestinationID)
If you are generating the dynamic elements after your ajax call, try using async:false.
$.ajax({
url: "abcd.html",
async:false
}).then(function())

I'm using Zend Framework 2.
I would like to know how to get data defined in html in my javascript code.
html
<tr class="MyClass" data-MyData="<?php echo json_encode($array);?>">
javascript
$(document).on('click','.MyClass', function () {
var temp =document.getElementsByClassName("data-MyData");
$.ajax({
url: path_server + "pathDefinedInMyConfig",
type: 'post',
encode: true,
dataType: 'json',
data: {
'temp ': temp
},
success: function (data) {
//some code
},
error: function () {
alert("ERROR");
}
});
});
The problem is I don't have access to row in my Controller method. And i want to have access to My $array defined in html in my Controller.
Problem is that you are trying to find a class by the name data-MyData, but the object you "want" to look for is "MyClass"
Try something like var temp =document.getElementsByClassName("MyClass").attr("data-MyData");
Even better is that since you click on the object with MyClass you can use $(this).attr('data-MyData');
then result will look like: var temp = $(this).attr('data-MyData');
Simply replace temp var assignment line:
var temp =document.getElementsByClassName("data-MyData");
with this one:
var temp = this.getAttribute("data-MyData");
Since you use jQuery use the following:
$('.MyClass').data('MyData')
or
$('.MyClass').attr('data-MyData')
use like this-
$(document).on('click','.MyClass', function () {
var temp =$(this).attr('data-MyData');
$.ajax({
url: path_server + "pathDefinedInMyConfig",
type: 'post',
encode: true,
dataType: 'json',
data: {
'temp ': temp
},
success: function (data) {
//some code
},
error: function () {
alert("ERROR");
}
});});
You have a wrong selector. document.getElementsByClassNames() returns the collections so you have to loop through to get the target element:
var temp =document.getElementsByClassName('MyClass');
[].forEach.call(temp, function(el){
console.log(el.dataset['MyData']);
});
or as you are using jQuery then you can use .data():
var temp =$(this).data("MyData");
and with javascript:
var temp =this.dataset["MyData"];
// var temp =this.dataset.MyData; // <---this way too.
I can do this, simply doing it in for loop, but I need to do it without using loop.
Is there any way to make it possible?
Below I am writing some of my code:
function submitFormArchive(Status) {
var siteUrl = $("#pageurl").val();
$("#archive-loader").show();
var myCheckboxes = new Array();
$("input[type='checkbox'][name='archive[]']:checked").each(function () {
myCheckboxes.push($(this).val());});
alert(myCheckboxes);///this one i am getting dynamic ids
$.ajax({
type: 'POST',
url: siteUrl + 'Appadmins/ajaxUpdateArchive',
data: {"myCheckboxes": myCheckboxes, "status": Status},
success: function (data) {
$("#remove-id-"+myCheckboxes).slice(myCheckboxes).remove();
}
});
return false;
}
<tr class="message_box" id='remove-id-<?php echo $list->id;?>'></tr>
This one in for loop
I am posting some part of codes.
$("#remove-id-" + myCheckboxes).slice(myCheckboxes).remove();
Is there any for multiple, maybe I have written wrong in this above code.
Try the code below
$("input[type='checkbox'][name='archive[]']:checked").each(function() {
myCheckboxes.push($(this).val());
});
alert(myCheckboxes); //40,39,38 //it can be any id ,as i made it dynamic .
// construct array of IDs here
var ids = myCheckboxes.map(function(id) { return "#remove-id-" + id; });
// ["#remove-id-40", "#remove-id-39", "#remove-id-38"]
// concat all id selectors together using comma `,`
var idSelector = ids.join(",");
// "#remove-id-40,#remove-id-39,#remove-id-38"
// remove all at once.
$(idSelector).remove();
$("input[type='checkbox'][name='archive[]']:checked").each(function() {
$("#remove-id-" + $(this).val()).remove();
});
I have a function for getting records from database on keyup event.
Here is my code:
function displaySearch(key) {
$.ajax({
type:"POST",
url:"searchprofile.php",
data:{
k:key
},
success:function(data){
var details_arr=data.split("+");
$('.searchresult').empty();
for(var i=0;i<details_arr.length-1;i++){
$('.searchresult').append("<div class='profile' id='searchprofile'><img class='profilepic' src='images/profile.jpg'/><div class='doctorname'><div class='pname' onclick='saveName("+details_arr[i]+")'>"+details_arr[i]+"</div></div></div>");
$('.searchresult').show();
$('.searchresult .profile').show();
}
details_arr.length=0;
}
});
}
But i am getting javascript error here saying "Unexpected token ILLEGAL".
How do i give the onclick function with the value of details_arr[i]?
Please help.
As you have jQuery, you really shouldn't inline code. As you see it makes it more difficult to handle quotes inside quoted strings (yes, you're missing quotes around your argument to saveName).
You may do this :
(function(i){
$('.searchresult').append(
"<div class='profile' id='searchprofile'>"
+ "<img class='profilepic' src='images/profile.jpg'/>"
+ "<div class='doctorname'>"
+ "<div id=someId class='pname'>"+details_arr[i] // <- give some Id
+"</div></div></div>"
);
$('#someId').click(function(){saveName(details_arr[i])});
})(i);
$('.searchresult').show();
Note that I used a closure to ensure that i has the needed value in the callback (not the value at end of iteration).
Be careful with the split: on most browsers "+aaa".split('+') makes ["", "aaa"] and as you don't iterate up to the end of the array, this sample string would made you iterate on nothing.
function openNow(x)
{
var pageUrl = '<%=ResolveUrl("~/OnFriends.php")%>'
$.ajax({
type: "POST",
url: pageUrl + '/CreateNew',
data: '{k: "'+ x +'"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success:function(data)
{
<---Now Do Your Code Hear--->
}
});
}
CreateNew is my web service what i created in .php file
I would use something like that
bare in mind ID must be unique inside a document (HTML Page)
because the content is generated on the fly; it's better to use the JQuery "on"
$(".pname").on("click", function (event) {
saveName($(this).text());
});
event handler to bind the click event
function displaySearch(key){
$.ajax({
type: "POST",
url: "searchprofile.php",
data: {
k: key
},
success: function(data) {
var details_arr = data.split("+");
var searchResults = "";
for (var i = 0; i < details_arr.length - 1; i++) {
searchResults += "<div class='profile'>" +
"<img class='profilepic' src='images/profile.jpg'/>" +
"<div class='doctorname'>" +
"<div class='pname'>" + details_arr[i] +
"</div></div></div>";
}
$('.searchresult').html(searchResults).show();
}
});
}
$(".pname").on("click", function (event) {
saveName($(this).text());
});
use the Jquery html to replace everything inside searchresult outside the loop that way it
will be called once not details_arr.length - 1 times
you should tell the line at which you are getting error
i think you did not specified you web service in ajax call at...
"url:"searchprofile.php"
Finally got the onclick function working. :)
Instead of appending the div everytime, i just editted my php page by adding the html i needed in the data that is returned in ajax.
I have a function which updates a database via ajax. My issue is then how to update the data displayed on the page to show updated details. The POST data can vary and therefore the datastring would be something like this:
var dataString = '[name resource we are editing]=1' +
'¶1='+ para1 +
'¶2=' + para2+
'¶3=' + para3
I want the function below to split or loop through each of the POST variables in the datastring to update the text of an element on the page. I cannot figure out how.
function editAccount(dataString, details, form){
status = $(".status");
$.ajax({
type: "POST",
url: "<?php echo BASE_PATH; ?>/edit/",
data: dataString,
success: function(response) {
$.each(response, function(key, value) {
success_code = key;
message = value;
});
if(success_code == 1){
status.text(message).addClass("valid");
//show details and hide form
$("#" + details).show();
$("#" + form).hide();
//HOW to do below?
//update details being displayed with datasource data
//loop through dataString to assign eg. $('#para1')text(para1);
} else {
status.text(message).addClass("invalid");
}
},
error: function(response){
status.text("There was a problem updating your details into our database. Please contact us to report this error.").addClass("invalid");
}
});
}
As mentioned in a previous comment, I would suggest declaring the dataString variable as an object:
var dataString = { '[name resource we are editing]' : 1,
'para1': para1,
'para2': para2,
'para3': para3
}
Now it'll be much easier to loop over the params, just using the function each, for instance, which you already use in your code:
$.each(dataString, function(key, value) {
// Do stuff with each param
});
EDIT:
As #Qpirate suggests, you also can use the javascript for loop:
for(var key in dataString){
// value => dataString[key]
}
I've looked over a lot of 'similar' q&a threads on SO but to be honest, as I don't have too much of a grip on js programming, I'm finding it difficult to make sense of a lot of the answers (as far as they may apply to my own situation).
The context is this, I have two php scripts one returning a list of customer_ids (json encoded) for a set period and the other returning their preferences for news feeds (json encoded).
I wrote the following, having googled a bit to get a basic understanding of how to setup an ajax function in jQuery:
$('document').ready(function() {
$.ajax({
type:'GET', url: 'cust_selection.php', data: '',
succes:function(cstmrid) {
var clistlen = cstmrid.length;
var i=0;
var cstmr;
for( ;cstmr=cstmrid[i++]; ) {
$('#adminPanel>ul>li').append("<a href='' onclick='alert("+cstmr+")' class='lst_admin basic'>"+cstmr+"</a>"); //alert to be replaced with a function call which passes customerid to the function below.
}
},
dataType:'json'
});
var cstmrid = "483972258"; //hardcoded for testing purposes
$.ajax({
type:'GET', url:'newsfpref.php?', data:'cref='+cstmrid,
success:function(npfdata) {
var item;
var n=0;
for( ;item=npfdata[n++]; ) {
var news = npfdata[n].nsource;
$('#adminMain>table>tbody').append("<tr><td>"+item+"</td></tr>");
}
},
dataType:'json'
});
});
Now from the first ajax function, I get a list of links which I want to be able to click to launch the second ajax function and pass it the customer id so that it can grab a list of the news sources that they've configured for their pages.
The alert and the hard-coded customer id both suggest that the functions are 'working', but when I try and adjust the first function so that:
...
$('#adminPanel>ul>li').append("<a href='' onclick='getCustomerNP("+cstmr+")' class='lst_admin basic'>"+cstmr+"</a>");
... is calling a modified version of the second function, as below:
...
function getCustomerNP(cstmrid) {
$.ajax({
type:'GET', url:'newsfpref.php?', data:'cref='+cstmrid,
success:function(nprfdata) {
var item;
var n=0;
for( ;item=npfdata[n++]; ) {
var news = npfdata[n].nsource;
$('#adminMain>table>tbody').append("<tr><td>"+item+"</td></tr>");
}
},
dataType:'json'
});
}
Everything seems to just fail at this point. The second function doesn't seem to 'receive' the variable and I'm not sure if it's something elementary that I've overlooked (like some muddled up " and ' placements) or if what I am trying to accomplish is actually not the way jQuery ajax functions interact with each other.
As you can see, I've cannibalised bits of code and ideas from many SO q&a threads, but copying without much of an understanding makes for a frustratingly dependent life.
I would appreciate as much - expansive - comment as you can provide, as well as a solution or two (naturally).
EDIT: Not to confuse anyone further, I've been modifying the above and correcting my (many) errors and typos along the way. At present, the code looks like below:
$('document').ready(function () {
$.ajax({
type: 'GET', url: 'cust_selection.php', data: '',
succes: function (cstmrid) {
var clistlen = cstmrid.length;
var i = 0;
var cstmr;
for (; cstmr = cstmrid[i++]; ) {
var a = $("<a href='' class='lst_admin basic'>" + cstmr + "</a>").click(function () {
getCustomerNP(cstmr)
})
$('#adminPanel>ul>li').append(a); //alert to be replaced with a function call which passes customerid to the function below.
}
},
dataType: 'json'
});
function getCustomerNP(cstmr) {
alert(cstmr);
}
});
You've got a typo in the $.ajax() success function within getCustomerNP(). The function declaration:
success:function(nprfdata) {
... has a parameter nprfdata, but then within the function you use npfdata (missing the r).
Also this code:
var item;
var n=0;
for( ;item=npfdata[n++]; ) {
var news = npfdata[n].nsource;
$('#adminMain>table>tbody').append("<tr><td>"+item+"</td></tr>");
}
...declares and sets variable news that you never use. And it doesn't seem right to increment n in the for test expression but then use n within the loop. You never set item to anything but you use it in your .append().
(Note also that JS doesn't have block scope, only function scope, so declaring variables inside an if or for loop doesn't limit them to that if or for block.)
I would not create inline onclick handlers like that. I'd probably do something more like this:
$('#adminPanel>ul>li').append("<a href='' data-cstmr='"+cstmr+"' class='lst_admin basic'>"+cstmr+"</a>");
...and then within the document ready setup a delegated event handler to catch the clicks on those anchors:
$('#adminPanel>ul>li').on('click', 'a.lst_admin', function() {
$.ajax({
type:'GET', url:'newsfpref.php?', data:'cref='+ $(this).attr('data-cstmr'),
success:function(npfdata) {
var item,
n=0,
// cache the jQuery object rather than reselecting on every iteration
$table = $('#adminMain>table>tbody');
// increment n only after the current iteration of the loop
for( ;item=npfdata[n]; n++) {
// change to use item
$table.append("<tr><td>"+item.nsource+"</td></tr>");
}
},
dataType:'json'
});
});
As you append your like with <a href='' onclick='getCustomerNP("+cstmr+")', Make sure you can access the function getCustomerNP.
Try to define getCustomerNP as
window.getCustomerNP = function(cstmrid) {
...
If you defined it in the $(document).ready(function(){ ... }) block, try this
$('document').ready(function () {
$.ajax({
type: 'GET', url: 'cust_selection.php', data: '',
succes: function (cstmrid) {
var clistlen = cstmrid.length;
var i = 0;
var cstmr;
for (; cstmr = cstmrid[i++]; ) {
var a = $("<a href='' class='lst_admin basic'>" + cstmr + "</a>").click(function () {
getCustomerNP(cstmr)
})
$('#adminPanel>ul>li').append(a); //alert to be replaced with a function call which passes customerid to the function below.
}
},
dataType: 'json'
});
function getCustomerNP(cstmrid) {
$.ajax({
type: 'GET', url: 'newsfpref.php?', data: 'cref=' + cstmrid,
success: function (nprfdata) {
var item;
var n = 0;
for (; item = npfdata[n++]; ) {
var news = npfdata[n].nsource;
$('#adminMain>table>tbody').append("<tr><td>" + item + "</td></tr>");
}
},
dataType: 'json'
});
}
});
