I've been looking an answer, but I don't find anything.
I got a JSF page with a button. This button call a JavaScript function :
function postAdd(id) {
var quant = document.getElementById("hell:quantite");
$('<form action="addto.xhtml" method="POST">' +
'<input type="hidden" name="productkey" value="' + id + '">' +
'<input type="hidden" name="howmany" value="' + quant.value + '">' +
'</form>').submit();
}
This works fine, I've tested it.
But in my addto.xhtml page, when I call param.productkey and param.howmany, I got nothing.
I used this method on other page and works fine but here, it doesn't work...
Any idea ?
Thanks.
The answer was to add to form inside the JSF page directly and get all parameters with #{function(param[form:idOfInput]}

I have a javascript capturing signatures and data.
The " are getting lost/cutoff and not conserving. I assume this is a URLEncoding issue.
This is the original.
'<input type="hidden" name="rvnotes" value="' + rvnotes + '"/>' +
And I have tried this, but still no luck. Any idea how to URL Encode the Javascript submission.
'<input type="hidden" name="rvnotes" value="' + encodeURIComponent(rvnotes) + '"/>' +
The trick must be done in <form>.
<form enctype="application/x-www-form-urlencoded" ...>
I have page with one form made in C# on the page there are several HTML elements. On button click I am using jQuery and add hidden fields than I submit form to external domain. Now the issue is, that it is sending all the parameters which I don't need. Is there any way that I can send only parameter that I need. I want to send parameter only in body.
Is there way to clear form parameter before adding parameter
jQuery Code
$("#aspnetForm").attr("action", "www.example.com");
$("#aspnetForm").attr("method", "post");
var params = a.split('?')[1].split('&'); /*custom string with key/value and sperated with & */
$.each(params, function (index) {
var paramsV = params[index].split('=');
$("#aspnetForm").append('<input type="hidden" name="' + paramsV[0] + '" value="' + paramsV[1] + '" /> ');
});
$("#aspnetForm").submit();
There more than 50 HTML element are added dynamically in my form and at each load it have different id. So I cannot disable those element in Jquery or javascript
I am using SharePoint 2013, it have its own master page where it add lot of elements which I don't have control, so I cannot individually disable them.
What I did is I created dynamically form add required parameter and then submit it.
Hope it can help somebody
$("#frm").remove(); /** remove extra frm before creating it **/
var frm = $('<form id="frm" action="' + _url + '" method="POST"></form>');
var params = a.split('?')[1].split('&'); /*custom string with key/value and sperated with & */
$.each(params, function (index) {
var paramsV = params[index].split('=');
frm.append('<input type="hidden" name="' + paramsV[0] + '" value="' + paramsV[1] + '" /> ');
});
frm.appendTo(document.body).submit();
I am trying to validate user using oAuth 2.0 which works fine and am obtaining user information from google using jquery which I want to send to the next page. So to do that, I am making form programmatically using jQuery and submitting using same. But unfortunately, form is not getting submitted. I have seen various answers on stack-overflow and have tried to implement using that things but none of them is working.
Here is my code..
customButtonRender.js
function onSuccess(googleUser){
console.log('Logged in as '+googleUser.getBasicProfile().getName());
var profile = googleUser.getBasicProfile();
submit_form(profile);
}
var submit_form = function(profile){
console.log(profile.getId());
console.log(profile.getName());
console.log(profile.getImageUrl());
console.log(profile.getEmail());
var user_url = "localhost:8080/NUConnect_JSP/jsp/home.jsp";
var val_form = $('<form data-ajax="false" method="POST" id="val_form" action="' + user_url + '">'+
'<input type="text" name="user_name" value="' + profile.getName() + '">'+
'<input type="text" name="user_email" value="' + profile.getEmail() + '">'+
'<input type="submit" name="user_submit" id="user_submit">'+
'</form>');
$('body').append(val_form);
// $("#val_form").submit();
// $("#val_form")[0].submit();
// $("#user_submit").click();
document.getElementById("val_form").submit();
console.log("After submit");
};
I have included customButtonRender.js file in head section.
As you can see I have tried various methods to submit form written in comments but none of them worked.
All the logs are printed successfully.
Do one thing if your data is not so confidential then pass that information in your url like this
window.location.href = "localhost:8080/NUConnect_JSP/jsp/home.jsp?user_name="+profile.getName()+"&user_email="+ profile.getEmail();
I have a div
<div id="updateChoice%s" class="text-center"></div>
which shows a the following upon a "updateText" button is clicked
function updateText(urlsafe) {
document.getElementById("updateChoice"+urlsafe).innerHTML +=
'<br><br><form id="dynForm" action="/updateText" method="post" >' +
'<textarea name="newContent" rows="5" cols="80"></textarea>' +
'<input type="hidden" name="update" value=' + urlsafe + '>' + '<br><br>' +
'<input class="choice" type="submit" value="Submit"></input> <button class="choice" onclick="cancelUpdate('+ urlsafe +')">Cancel</button>' +
'</form>';
}
I want to cancel the updating of the text but it doesn't work unless "newContent" is empty, here is /updateText file and cancelUpdate(urlsafe)
/updateText:
class UpdateText(webapp2.RequestHandler):
def post(self):
greeting_key = ndb.Key(urlsafe=self.request.get('update'))
event = greeting_key.get();
if(self.request.get('newContent') != ''):
event.content = self.request.get('newContent');
event.put();
self.redirect('/events');
cancelUpdate(urlsafe):
function cancelUpdate(urlsafe) {
document.getElementByName("newContent").innerHTML="";
document.getElementById("dynForm").submit();
}
any ideas?
The /updateText handler remains on not updating the text if upon submission it is empty, so do not change anything:
In the cancelUpdate(urlsafe) function, use this aproach:
function cancelUpdate(urlsafe) {
document.getElementById("updateChoice"+urlsafe).innerHTML = "";
}
Add \' to the parameter urlsafe as you pass it and not ". So here is correct javascript function call to div#updateChoice%s is:
function updateText(urlsafe) {
document.getElementById("updateChoice"+urlsafe).innerHTML =
'<br><br><form id="dynForm" action="/updateText" method="post" >' +
'<textarea name="newContent" rows="5" cols="80"></textarea>' +
'<input type="hidden" name="update" value=' + urlsafe + '>' + '<br><br>' +
'<input class="choice" type="submit" value="Submit"></input><button type="button" class="choice" onClick="cancelUpdate(\''+ urlsafe +'\')">Cancel</button>' +
'</form>';
}
Your question is very difficult to understand (What do you mean by "cancel the updating of the text"? What did you expect to happen? What exactly "doesn't work"?).
Also, there are multiple issues with the code you provided (none of which have to do anything with GAE, Python or webapp2), here are a few that might be helpful to resolve your issue:
1) Your cancelUpdate function accepts a urlsafe parameter but is not using it.
2) In your cancelUpdate function you're using a non-existing function getElementByName, you probably meant to use its plural version getElementsByName()
3)
On the same document.getElementByName("newContent").innerHTML=""; line you are retreiving an element with the name newContent which is a <textarea> element and are attempting to empty its innerHTML property, but a <textarea> doesn't have one. If you want to empty a <textarea>'s contents - you need to do document.getElementByName("newContent").value=""; instead.
Since your cancelUpdate function has an unused parameter urlsafe and although it's not clear what your issue is but since in your updateText function you are creating an element with id="updateChoice"+urlsafe and assuming that when you hit cancel - you also want to destroy that form, then your cancelUpdate would look as simple as this:
function cancelUpdate(urlsafe) {
document.getElementById("updateChoice"+urlsafe).innerHTML = "";
}
4)
Your "Cancel" button doesn't have a type specified which means it will default to submit even when you don't want to submit the form so you need to add type="button" to prevent the submission.
You are calling document.getElementById("dynForm").submit(); in your cancelUpdate function which in the combination with the previous issue will submit your form twice.
I have a simple ui which has a link that says "add item". When this is clicked, a pair of input boxes appears below it. If it is clicked again, yet another pair appears. I'm trying to think of the best way to generate these elements and turn it into some sort of json array of key value pairs (the first input element in each pair being the key and the second input element being the value).
Right now I just have a counter and I generate the ids using it, such as (in the click event of the "add item" link):
$('#features').append('<input id="feature-name-' + self.featureCount + '" type="text" name="asdf" /><a class="delete-feature" data-id="' + self.featureCount + '">Delete</a><input id="feature-description-' + self.featureCount + '" type="text" name="asdf" />');
I don't know what to use as the "name" attributes in order to make it easy to create a json array from them.
you can do something like this without using id attributes.
$('#features').append('<div><input type="text" />
<a class="delete-feature" data-id="' + self.featureCount + '">Delete</a><input type="text" /></div>');
And your javascript,
var yourArray=[];
$('#yourButton').click(function(){
$('#features div').each(function(){
var div=$(this);
var k=$('input:first',div).val();
var v=$('input:first',div).next().val();
yourArray.push({key:k, value: v});
});
});
It doesn't matter what you use for a name attribute, so long as there name and description names are different. Let's say that these elements are all appended to a form with the id myform. Give each pair its own wrapper object. Here, I've used a div, but a fieldset is equally appropriate.
$('#features').append(
'<div class="feature-div">
'<input id="feature-name-' + self.featureCount + '" type="text" name="asdf" />' +
'<a class="delete-feature" data-id="' + self.featureCount + '">Delete</a>' +
'<input id="featurena-description-' + self.featureCount + '" type="text" name="asdf" />' +
'</div>');
Now, it's possible to extract each pair sensibly:
var myarray = [];
$('#myform .feature-div').each(function(i, v) {
myarray.push([
$('input[name=name]', v).val(), $('input[name=description]', v).val()]);
});
Or however you want the data to be presented.
