I have this jQuery code:
html += '<tr>';
html += '<td>AAA</td>';
html += '<td>BBB</td>';
html += '<td>CCC</td>';
html += '<td>DDD</td>';
html += '<td>EEE</td>';
html += '<td>FFF</td>';
html += '</tr>';
$(html).appendTo("#fabricanteBody");
$(html).appendTo("#selFabricanteBody");
How do I remove the last td (html += '<td>FFF</td>') element on the html var before append it to #selFabricanteBody?
$('tr > td:last-child').remove();
or
$('tr > td').last().remove();
see demo HERE and HERE.

im curently working on a script that pulls data from google sheets and transforms it in to a html table. but i have links in my google sheets tabele so i want that these links get but in a button that looks nice but icant figure out how to do that.
i curently have this loob
for (var i = 0; i < entry.length; i++) {
html += '<tr>';
html += '<td>' + entry[i]['gsx$komponente']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$name']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$hersteller']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$preis']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$link']['$t'] + '</td>';
html += '</tr>';
}
html += '</table>';
the entry[i]['gsx$link']['$t'] gets me the links i just cant get it to work inside a button
if you have any idea how i can solve this problem please help me
here is the Complete code
<!DOCTYPE html>
<meta charset="ISO-8859-1">
<html>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js">

})
.ajaxStop(function() {
loading.hide();
});
</script>
<div class="console"></div>
<div class="loading">

</body>
</html>
You just need to wrap the link inside <a> tag
for (var i = 0; i < entry.length; i++) {
html += '<tr>';
html += '<td>' + entry[i]['gsx$komponente']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$name']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$hersteller']['$t'] + '</td>';
html += '<td>' + entry[i]['gsx$preis']['$t'] + '</td>';
html += '<td><a href=' + entry[i]['gsx$link']['$t'] + '>' +entry[i]['gsx$link']['$t'] + '</a></td>';
html += '</tr>';
}
this is my simple hardcoded version.
$(document).ready(function(){
$.support.cors = true;
var this_id = '123456789123456';
$.ajax({
url: 'https://thisservice/delivery/'+this_id,
type: "get",
dataType: "json",
data: { },
success: function(response){
console.log(response);
var html = '';
html += '<tr>';
html += '<th>Customer Name: </th><td>'+response.custName+'</td>';
html += '</tr>';
html += '<tr>';
html += '<th>Address Line1:</th><td>'+response.addrLine1+'</td>';
html += '</tr>';
html += '<tr>';
html += '<th>Address Line2:</th><td>'+response.addrLine2+'</td>';
html += '</tr>';
html += '<th>Address Line3:</th><td>'+response.addrLine3+'</td>';
html += '</tr>';
html += '<th>Address Line4:</th><td>'+response.addrLine4+'</td>';
html += '</tr>';
html += '<th>Address Line5:</th><td>'+response.addrLine5+'</td>';
html += '</tr>';
html += '<th>Address Line6:</th><td>'+response.addrLine6+'</td>';
html += '</tr>';
html += '<th>Customer PostCode:</th><td>'+response.custPostCode+'</td>';
html += '</tr>';
$('#theDelivery').append(html);
}
})});
the code above works perfectly fine, however im now working to make this_id as a url parameter, so when the webpage is called along with a valid 16th digit number as a substring, it will return the contents of the objects that i am trying to access from this webservice.
How exactly is it done? i have attempted to do this in the code below, but no luck.
<script type="text/javascript">
function getthisId(this_id){
$.support.cors = true;
$.ajax({
type: "get",
url: 'https://thisservice/delivery/'+this_id,
dataType: "json",
cache: false,
data: { this_id },
success: function (response) {
console.log(response);
var html = '';
html += '<tr>';
html += '<th>Customer Name: </th><td>'+response.custName+'</td>';
html += '</tr>';
html += '<tr>';
html += '<th>Address Line1:</th><td>'+response.addrLine1+'</td>';
html += '</tr>';
html += '<tr>';
html += '<th>Address Line2:</th><td>'+response.addrLine2+'</td>';
html += '</tr>';
html += '<th>Address Line3:</th><td>'+response.addrLine3+'</td>';
html += '</tr>';
html += '<th>Address Line4:</th><td>'+response.addrLine4+'</td>';
html += '</tr>';
html += '<th>Address Line5:</th><td>'+response.addrLine5+'</td>';
html += '</tr>';
html += '<th>Address Line6:</th><td>'+response.addrLine6+'</td>';
html += '</tr>';
html += '<th>Customer PostCode:</th><td>'+response.custPostCode+'</td>';
html += '</tr>';
$('#theDelivery').append(html);
}
});
}
$(document).ready(function () {
getthisId(this_id);
});
this error occurs:
Uncaught ReferenceError: this_id is not defined
at HTMLDocument.<anonymous> (1032987988503654:59)

im very new to this, any help would be great :)
The server side is expecting the value in a parameter named parcel_id, so you need to provide that as the key in the object you provide to data, like this:
data: { parcel_id: this_id },
you should do like this
'https://thisservice/delivery/?id='+this_id
Above code generate HTML table using JSON output.
But, my problem is, after this JQuery runs, other page content is not shown.
<script>
$(document).ready(function () {
var html = '<table class="table table-striped">';
html += '<tr>';
var flag = 0;
var data2 = <?php echo $data; ?>;
$.each(data2[0], function(index, value){
html += '<th>'+index+'</th>';
});
html += '</tr>';
$.each(data2, function(index, value){
html += '<tr>';
$.each(value, function(index2, value2){
html += '<td>'+value2+'</td>';
});
html += '<tr>';
});
html += '</table>';
$('body').html(html);
console.log(html);
});
</script>
when the page loads, content should disappear and it should shows particular table only.
change this
$('body').html(html);
with
$('body').append(html);
Probably cause is
$('body').html(html);
Because html() method will change the content of body elements. You should use
$('body').append(html);
to insert content at the end of body elements.
you miss : html += '</tr>';
please check with full code
<script>
$(document).ready(function () {
var html = '<table class="table table-striped">';
html += '<tr>';
var flag = 0;
var data2 = <?php echo $data; ?>;
$.each(data2[0], function(index, value){
html += '<th>'+index+'</th>';
});
html += '</tr>';
$.each(data2, function(index, value){
html += '<tr>';
$.each(value, function(index2, value2){
html += '<td>'+value2+'</td>';
});
html += '</tr>';
});
html += '</table>';
$('body').html(html);
console.log(html);
});

I am creating html-elements in a loop, and want to attach event-handlers to some of the elements. This handlers need to know the id of the element that fired the event, so I added the elements id's as a parameter of the binded function, but anyway what element I click at the end, the function always received the id of the last element, not of the element that I clicked.
Here is the code (more simplified version in the next code-block) (I'm using jQuery, but this is not a jQuery-problem, just a JavaScript-problem)
receiveObjects = function (JSONobj, StatusString, jqXHR) {
var html, i, el;
// error-handling is not shown here
html = '<table>';
for (i = 0; i < JSONobj.list.length; i++) {
el = JSONobj.list[i];
html += '<tr>';
html += '<td class="td1" id="td1'+el.itemID+'">';
html += '<table>';
html += '<tr>';
html += '<td><img id="up9x'+el.itemID+'" src="pics/arrowUp9.png" alt="" style="width:25px;height:66px;"></td>';
html += '<td><img id="up3x'+el.itemID+'" src="pics/arrowUp3.png" alt="" style="width:25px;height:66px;"></td>';
html += '<td><img id="up1x'+el.itemID+'" src="pics/arrowUp1.png" alt="" style="width:25px;height:66px;"></td>';
html += '</tr>';
html += '<tr>';
html += '<td><img id="down9x'+el.itemID+'" src="pics/arrowDown9.png" alt="" style="width:25px;height:66px;"></td>';
html += '<td><img id="down3x'+el.itemID+'" src="pics/arrowDown3.png" alt="" style="width:25px;height:66px;"></td>';
html += '<td><img id="down1x'+el.itemID+'" src="pics/arrowDown1.png" alt="" style="width:25px;height:66px;"></td>';
html += '</tr>';
html += '<tr>';
html += '<td colspan="3">';
html += '<div><button id="delete'+el.itemID+'" name="delete'+el.itemID+'" value="delete'+el.itemID+'">delete</button></div>';
html += '<div id="saveDiv'+el.itemID+'" style="display:none;">';
html += '<button id="save'+el.itemID+'" name="save'+el.itemID+'" value="save'+el.itemID+'">save</button>';
html += '</div>';
html += '</td>';
html += '</tr>';
html += '</table>';
html += '</td>';
html += '<td class="td2" id="td2'+el.itemID+'">';
html += '<table>';
html += '<tr>';
html += '<td>Titel </td>';
html += '<td>';
html += '<input class="grau" type="text" id="inTitel'+el.itemID+'" size="30" maxsize="50" value="'+el.Titel+'">';
html += '</td>';
html += '</tr>';
html += '<tr>';
html += '<td>ET</td>';
html += '<td>';
html += '<input class="grau" type="text" id="inET'+el.itemID+'" size="20" maxsize="30" value="'+el.ET+'">';
html += '</td>';
html += '</tr>';
html += '<tr>';
html += '<td>Text </td>';
html += '<td>';
html += '<textarea class="grau" id="inText'+el.itemID+'" rows="4" cols="30">'+el.Text+'</textarea>';
html += '</td>';
html += '</tr>';
html += '</table>';
html += '<button id="loadPdf'+el.itemID+'" name="loadPdf'+el.itemID+'" value="loadPdf'+el.itemID+'">upload pdf</button>';
html += '</td>';
html += '<td class="td3" id="td3'+el.itemID+'">';
html += '<img src="'+el.pic+'">';
html += '<div>';
html += '<button id="newPic'+el.itemID+'" name="newPic'+el.itemID+'" value="newPic'+el.itemID+'">create pic from pdf</button> ';
html += '</div>';
html += '</td>';
html += '</tr>';
}
html += '</table><div class="ErrorMsg" id="changeRedError"></div>';
$('#workBlock').html(html);
//after the elements are inserted into the dom, the eventhandlers should be binded:
for (i = 0; i < JSONobj.list.length; i++) {
el = JSONobj.list[i];
$('#up9x'+el.itemID).on('click',function(){evHd.clickMove(el.itemID,-9);})
$('#up3x'+el.itemID).on('click',function(){evHd.clickMove(el.itemID,-3);})
$('#up1x'+el.itemID).on('click',function(){evHd.clickMove(el.itemID,-1);})
$('#down9x'+el.itemID).on('click',function(){evHd.clickMove(el.itemID,9);})
$('#down3x'+el.itemID).on('click',function(){evHd.clickMove(el.itemID,3);})
$('#down1x'+el.itemID).on('click',function(){evHd.clickMove(el.itemID,1);})
$('#delete'+el.itemID).on('click',function(){evHd.clickDelete(el.itemID);})
$('#save'+el.itemID).on('click',function(){evHd.clickSave(el.itemID);})
$('#inTitel'+el.itemID).on('change keyup paste mouseup',function(){evHd.changed(el.itemID);})
$('#inET'+el.itemID).on('change keyup paste mouseup',function(){evHd.changed(el.itemID);})
$('#inText'+el.itemID).on('change keyup paste mouseup',function(){evHd.changed(el.itemID);})
$('#loadPdf'+el.itemID).on('click',function(){evHd.clickLoadPdf(el.itemID);})
$('#newPic'+el.itemID).on('click',function(){evHd.clickNewPic(el.itemID);})
}
}
The problem must be located in the way how I attach the id (el.itemID) to the event-handler function. Simplified:
for (i = 0; i < 500; i++) {
el = JSONobj.list[i];
$('#prefix'+i).on('click',function(){
handler(i); //this seems to be problematic
})
}
I think I know where the problem is, but I have no idea how to solve it. Can you help, please?
This is a very common mistake, due to JavaScript's concept of closures (function plus pointers to all the variables outside the function that have been referenced in the function body). You can solve this with an IIFE (immediately invoked function expression):
for (i = 0; i < 500; i++) {
(function(num) {
$('#prefix' + num).on('click',function() {
handler(num);
})
})(i);
}
This immediately invoked function will create a new scope and thus have the correct i saved in num. Otherwise, JavaScript's closure (the function keeps a pointer on i and thus always references 500 after the for loop ended) will mess with your event handlers.
I have the following script:
<script type="text/javascript">
function addRow() {
var count = $("#tblUploadDocs").prop('rows').length;
count += 1;
alert(count);
var html = '<tr>';
html += '<td><input type="file" name="files" id="file' + count + '" /></td>';
html += '<td>Bu dilden</td>';
html += '<tr>';
alert(html);
}
</script>
I am trying to insert the following line into the script, but could not achieve the desired result:
<td>#Html.DropDownList("ddlFromLanguage1", ViewBag.Languages as SelectList)</td>
I tried both and #: but could not make it work. I am looking forward to hearing to a solution.
Thanks in advance
Use the <text> pseudo-element, as described here, to force the razor compiler back into content mode:
<script type="text/javascript">
function addRow() {
<text>
var count = $("#tblUploadDocs").prop('rows').length;
count += 1;
alert(count);
var html = '<tr>';
html += '<td><input type="file" name="files" id="file' + count + '" /></td>';
html += '<td>Bu dilden</td>';
html += '<tr>';
alert(html);
</text>
}
</script>
