is exactly the sort of code that leads to trouble. You need to traverse in a logical fashion starting at the top node, and at each point check whether the child is the correct one you are looking for.

indeed, that's the whole point. I find this XmlDocument system far too complicated or I'm using it wrong somehow. I'm not against loops and if's/switch statements, but it would end up ridiculously complicated in my opinion.
eg.
<xml>
<mytag>the value of this tag</mytag>
</xml>
if you get to the tag "mytag" you get 2 nodes: one for the "mytag" and one for the contents of mytag ("the value of this tag").
In my mind, I would call "getValue" or something on the mytag node to get the contents. In XmlDocument you need to call the childnode first before getValue. Which is just weird.

Modern versions of Javascript have querySelector() and querySelectorAll(), which are a lot easier to use than traversing the tree - check your documentation (and document object) to see if you have them. You can basically pick out nodes using CSS selectors.
As an alternative there is XPath - it uses expressions to drill down into the tree, just not in the familiar CSS-way that querySelector and querySelectorAll do it.
The querySelector/querySelectorAll functions are available in all the modern browsers, but it looks like XPath is in everything apart from Internet Explorer.

thanks! I'll certainly have a look at that.

Greetings experts.
I have used this script before on page with Next, Previous, Submit code and it worked then.
Now, I am trying to use it on a similar application where users will fill the first page and click Next to go to the next page.
Usually, if a required field is not completed and the user clicks Next, a message will display warning the user that a required field must be filled up with the message displaying next to that field.
With the script, you could click Next without completing a required field and it will go to the next page.
You could even click submit and your data will submit without being asked to complete required fields.
What am I doing wrong?

Have you checked that both jQuery and the jQuery Validation scripts are included before this script block?
Have you checked that the <form> element's id is set to "msform"?
Are there any script errors in the browser's developer console?

I am so sorry Richard,
I always forget to check the browser developer console for info.
I just did now and it turns out that I did not put jquery validate library at the of the page.
I did just that now it works, sort of.
It displays all the messages before user has a chance to invoke.
We would prefer that the textboxes look normal until user skips required field.
Many thanks for your prompt response as usual.

Probably because you're calling the .valid function immediately, rather than waiting until the form is submitted. 
<script>
...
if ((!$('#msform').valid())) {
return false;
}
</script>
Those lines should probably be inside a handler for the form's submit event:
$("#msform").sumbit(function(evt){
if (!$(this).valid()) {
evt.preventDefault();
}
});
However, I think the jQuery validation library already handles this for you, so they may not be required at all.

Now it works perfectly!

How to create edit button to table that is being created dynamically so as to edit the row of a table.
|
|
|
|
|
Create the button as part of the row and have within the buttons attributes appropriate references to it's particular content.
This is a very important technique and I suggest strongly you master the concept of creating references to items concurrently with creating the item.

Hi there,
I need to insert blank pages in a large PDF doc only once after it finds a specific word on that page and is odd.
For eg: If the page has the word "Print this document" and the page number is 5, then insert a blank page only after it.
If the page has the word "Print this document" and the page number is 6, then insert a blank page before and after it.
If the page does not have the word "Print this document", do nothing.
The code sounds simple but I am just not sure.
Thanks if anyone could help would really appreciate it.

Are you sure you are going to do this in JavaScript?
|
|
|
|
|
Yes Richard. I am using the JavaScript function in Adobe. Its just that I am not too familiar with find the text in a document, and then insert pages.
|
|
|
|
|
In that case I would suggest studying the Adobe documentation.

Hi greeting to the comunity!!
I´m trying to display the info from a array json dinamically into an html table, but I'm dont really undertand what I`m doing wrong
so, I`m taking three columns from my MySql Table (Name,city and Provinz),so I need a row for each row of my sql table, if a obtain three rows , that is in total 9 cells,ordered in three rows, 3 each..
onload() on body calls the function
function verDetalleNegocio(){
var localidad=getLocalidad();
var negocio=getNegocio();
var datos={'loc':localidad,'neg':negocio};
var datosS=JSON.stringify(datos);
if(localidad!=="" && negocio!==""){
$.ajax({
type:"POST",
data:"datos="+datosS,
dataType:'json',
cache:false,
url:"<?=$this->basePath("web/negocios/detallenegocioajax")?>",
success:function(datos){
var celdas=datos.length;
var filas=celdas/3;
for(i=0;i<datos.length;i++)
{
$("#tabdat").append("<tr>");
$("#tabdat").append("<td>"+datos[i]+"</td>");
$("#tabdat").append("</tr>");
}
}
});
}else{
return null;
}
}
here, I habe my html table:
</head>
<body onload="verDetalleNegocio()">
<table id="tabdat" class="tablaNeg" border=1>
<thead>
<tr>
<th>Nombre</th>
<th>Localidad</th>
<th>Provincia</th>
</tr>
</thead>
<tbody></tbody>
</table>
</body>
and finally, thatt the way the results are display, I would like to show the rows, one on top of the other, and not one next to the other, hoy could say in the iteration, every three, a new row!!!
Thanks!!!

It looks like you are creating a new row for each item in the code:
for(i=0;i<datos.length;i++)
{
$("#tabdat").append("<tr>");
$("#tabdat").append("<td>"+datos[i]+"</td>");
$("#tabdat").append("</tr>");
}
You should move the <tr> tags outside the loop thus:
$("#tabdat").append("<tr>");
for(i=0;i<datos.length;i++)
{
$("#tabdat").append("<td>"+datos[i]+"</td>");
}
$("#tabdat").append("</tr>");

Hi!!
thanks a lot for your reply!!
unfortunatelly, after the changes you proposed me, I get the same result 
I`ll keep trying!!
|
|
|
|

It would help us if you showed the actual code you use, and the HTML that is produced when you run it. You can edit your question and add the update information.

Hi again!!
thanks for your reply, so I put it down the proposal of a colleage from stackoverflow...there I posted the same question..
so the json array comes from the controller, filtered with json_encode();, this is the copy paste from the Chome debugger..so as you can see, I want to display the array of 9 positions in three
rows one under other, and each with three cells..
0: "Naviera Riazor"
1: "La Coruña"
2: "La Coruña"
3: "Barcos Texeiro"
4: "La Coruña"
5: "La Coruña"
6: "Barcos de Vela Riazor"
7: "La Coruña"
8: "La Coruña"
length: 9
this is the table, with a script, that I dont know if is "key" so that everything goes good..
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="tabdat" border=1 style="margin-top: 300px;">
<thead>
<tr>
<th>Nombre</th>
<th>Localidad</th>
<th>Provincia</th>
</tr>
</thead>
<tbody></tbody>
</table>
</body>
and here is the function verDetalleNegocio(), that I invoke on the body with the onload method, inside I do the
loop, and try to display on the #tabdat, under...
function verDetalleNegocio(){
var localidad=getLocalidad();
var negocio=getNegocio();
var datos={'loc':localidad,'neg':negocio};
var datosS=JSON.stringify(datos);
if(localidad!=="" && negocio!==""){
$.ajax({
type:"POST",
data:"datos="+datosS,
dataType:'json',
cache:false,
url:"<?=$this->basePath("web/negocios/detallenegocioajax")?>",
success:function(datos){
html = "";
for(i=0; i<datos.length; i++){
html += "<tr>"
html += "<td>"+datos[i]+"</td>";
html += "<td>"+datos[i]+"</td>";
html += "<td>"+datos[i]+"</td>";
html += "</tr>";
}
$("#tabdat tbody").append(html);
}
});
}else{
return null;
}
}
and finally the result that I obtain on the screen..as you can see, the information is displayed twice...please, tell me If i can put more infomation...thanks

Look at your code, in the loop you are printing the same item html += "<td>"+datos[i]+"</td>"; three times. I showed you what the code should be in my original response.
|

|

Hi!!
thanks for your reply..you`re right...
now I changed the format of the array, and now its like this:
0: ["Naviera Riazor"]
1: {1: "La Coruña"}
2: {2: "La Coruña"}
3: ["Barcos Texeiro"]
4: {1: "La Coruña"}
5: {2: "La Coruña"}
6: ["Barcos de Vela Riazor"]
7: {1: "La Coruña"}
8: {2: "La Coruña"}
length: 9
The problem is, that I dont find the way to display properly the info in the html, table,I tryed with a double loop, first for, and secon inner do...while, and two for consecutives, thats mean one inside the other..but It doesn`t work...to ne honest, sometimes I think I'm doing it very complicated, maybe there is another way to do it more simple..
var html="";
var celdas=datos.length;
var filas=celdas/3;
var cont=0;
for(f=0;f<filas;f++)
{
do{
html+="<tr>";
html+="<td>"+datos[f][cont]+"</td>";
html+="</tr>";
cont++;
}while(cont<=2);
}
$("#tabdat tbody").append(html);
Thanks!!

Loo,k at the data and decide how many items you want in each row. You then can set the values for your loop. For each iteration of the loop:
1. Emit a <tr> element.
2. Emit a <td> followed by the first data item, followed by </td>
3. Repeat number 2 for each remaining data item.
4. Emit a </tr> item for the end of the row.
