Hi,
Why dont you try JQuery confirm Plugin
Check it out !!
http://myclabs.github.io/jquery.confirm/[^]
Or
if (confirm('Are you sure you want to add a new row')) {
//alert('You have added a new Row');
return true;
} else {
//alert('Cancel is clicked');
return false;
}
|
|

Do reply to OP's message instead of mine.
If this is reply to me,
OP is a beginner so I have suggested him an easy one which is traditional using javascript. Many people used that script for delete operation inside GridView. Clickety[^]

Hi,
I need help on consuming external WCF REST service and display the data using angular.js.
I have (url:http://localhost/service1.svc/flowers) that fetches WCF REST service which returns data in JSON format as given below:
[{"FlowerName":"Jasmine","Place":"Mysore"},{"FlowerName":"Rose","Place":"Bangalore"},{"FlowerName":"Sun flower","Place":"Belgaum"}]
I need to display the above data in a html with rows and columns respectively.
Can anyone please help me with suitable sample code?
Kind regards,
Ram

You can try to use a View template, it will fit your needs, I'm using one right now (doT.js).
It will take you some time to understand it, but after that, displaying your objects will be a game !

|

i know how to do it jquery
$.ajax({
type: "GET",
url: "http://localhost/service1.svc/flowers",
success:function(data){
var x=JSON.parse(data);
var builtHtml="<tr><td>FlowerName</td><td>Place</td></tr>";
for(i=0;i<x.length;i++)
{builtHtml+="<tr><td>"+x[i].FlowerName+"</td><td>"+x[i].Place+"</td></tr>"}
$("#tableID").append(builtHtml)
}})
But i never used angular.js before

I have been trying to get the method to work. I have seen and tried quite a few online examples including the example found on W3C (which is below). Even on their site, it doesn't work. I have tried to get the method to work by:
Refresh the page, using back and forward buttons, and closing the window. Nothing happens in IE, Firefox or Chrome. I am at a loss as to why this doesn't work.
<!DOCTYPE html>
<html>
<head>
<script>
function myFunction()
{
alert("Thank you for visiting W3Schools!");
}
</script>
</head>
<body onunload="myFunction()">
<h1>Welcome to my Home Page</h1>
<p>Close this window or press F5 to reload the page.</p>
</body>
</html>

I pasted your code as is into a file and it runs as it should. Perhaps you have a typing error in your actual code?

First, add a javascript code in the header to validate that all radios are checked, if all checked, proceed to submit else cancel the submit. Next you have to add a submit button in the form, last, modify the form tag to add an onsubmit event to call the validation javascript code. See example:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<script type="text/javascript">
function validateRadio()
{
var inputs = myform.elements;
var radios = [];
for (var i = 0; i < inputs.length; ++i) {
if (inputs[i].type == 'radio') {
radios.push(inputs[i]);
}
}
var countChecked = 0;
for (var j = 0; j < radios.length; j++) {
if (radios[j].checked) {
countChecked++;
}
}
if (countChecked != radios.length / 2){
alert("All questions must be answered.");
return false;
} else {
return true;
}
}
</script>
</head>
</head>
<body>
<form name="myform" method="post"
onSubmit="return validateRadio()" action="anotherfile.php">
<!-- your other code --->
</table>
<input type="submit" name="submit" id="submit" value="Submit">
</form>
</body>

Thanks Peter Leow...

I add another code for counting button with value=1
I keep getting the result = 0
Can you tell me what do i miss?
Here's the code
for (var i = 0; i < inputs.length; ++i) {
if (inputs[i].type == 'radio') {
radios.push(inputs[i]);
}
}
var countChecked = 0;
for (var j = 0; j < radios.length; j++) {
if (radios[j].checked) {
countChecked++;
}
var answeramount = 0;
if(radios[j].checked && radios[j].value==1){
answeramount++;
}
}
I get it fix by making new loop. But i still confused why the first code didn't work...
Here's the new code
var countChecked = 0;
for (var j = 0; j < radios.length; j++) {
if (radios[j].checked) {
countChecked++;
}
}
var answeramount = 0;
for (var k = 0; k < radios.length; k++){
if(radios[k].checked && radios[k].value==1){
answeramount++;
}
}
|
|
|
|
|
That is because you have placed this line of code inside the for loop which keep resetting it to zero.
var answeramount = 0;

Hi,
I know that objects in javascript, like in many other languages, holds the reference to the object itself and primitive types like number bool holds the actual value.
I have something like this:
function manager()
{
var anObject = {prop1: 1, prop2: 2};
.
.
.
return
{
getMyObject: function(){
return anObject;
}
}
My question is why when I do something like this:
var m = new manager();
var o = m.getMyObject();
o = {a: 10, b: 20};
The actual value in 'o' which is a reference type is not changed when I do this:
var o2 = m.getMyObject();
what is actually set in the variable 'o'?
and how can I make it persist in the above
|

|
|

Your code currently does the following:
- Store the object returned from
getMyObject in a variable called o; - Store a new object in the
o variable; - Store the object returned from
getMyObject in a variable called o2;
It should be fairly obvious why o and o2 do not point to the same object - step 2 makes o point to a new, different object.
If you want your changes to the object to be persisted for future calls of the getMyObject function, you need to change the properties of the object returned from that function:
var m = new manager();
var o = m.getMyObject();
o.prop1 = 10;
o.prop2 = 20;
var o2 = m.getMyObject();

Thanks for your reply Richard,
I understood the sequence but there's still something not clear for me.
A variable which holds a reference, basically holds a pointer to an object.
If I set variable 'a' which holds a reference to object1 to a new variable called 'b', both of them
will have a pointer that should point to the same place i.e. object1.
Maybe I'm confusing it with a language like c# but if I set a new object to variable 'a' called 'object2',
I'm creating a new pointer to that new object. I expect the place in memory where the original pointer which pointed to 'object1' will change and point to object2 for both 'a' and 'b'.
But I see that's not happening.
'a' points to the new object while 'b' still points to the older one.

No. If variables a and b point to object1, and you change variable a to point to object2, variable b will not be affected.
If you're more comfortable with C#, consider the following contrived example:
string a = string.Empty;
string b = string.Empty;
a = "Hello";
What value do you think will be in b after you run this code?
If the language followed your idea, since both variables start out pointing to the same string, when you change a to point to the string "Hello", it would automatically change b as well. That would make it virtually impossible to write a program, since all variables and fields of the same type would automatically be pointing to the same instance of that type.
Think of it like postal addresses: person a lives at address1, and person b also lives at address1. If you change the street-name for address1, that change affects both people. If person a moves to address2, that doesn't necessarily mean that person b moves as well.
