var formSerializeArray = $('QDiv').serializeArray();
QDiv contains all the input controls... I have used serializeArray() and serialize() as well... But it is not working... meaning it is returning "null" eventhought the div contains controls.
some one please help me... what am i missing?
It's important to take #Maciej's answer into consideration first.
You should also check if your form elements have a name attribute or else they won't be included when you trigger serialize() or serializeArray().

If you’re using some recent jQuery, make sure you’re using "#" with id selectors, ie.:
var formSerializeArray = $('#QDiv').serializeArray();

I have a very big handsontable. I have dropdown columns defined, but, the values for the sources are retrieved with AJAX.
How can I set the "source" property of a "column" of type "dropdown" dynamically?
Regards!
You can, and should, use:
hotInstance.updateSettings({
columns: getNewColumns()
})
Where getNewColumns() would return an array of columns with the data and new source (or make the AJAX call from in here). That should do it!
Thank you for the answer ZekeDroid.
I was able to solve my issue.
First lets talk about a problem in the angular directive:
I am using the handsontable's angular directive. Two things happen: 1. If I associated the datarows attribute to a nested variale in the model, for example $scope.hot.data, then when I change the value of the model ( $scope.hot.data ) the grid ui is not refreshed. I am pretty sure this is an issue with the directive. Now: 2. Assume I use $scope.data and I update its value (this is the model right), then the grid ui is not refreshed either. I have to do something like hotInstance.updateSettings({data: newData}) as well.
I have to do both things; that is, update the model and call the update settings method. This is the only way I could get it work properly.
Note: if I do $scope.$apply() instead the updateSettings, I get an error in the console.
I have textarea which is required field. I've found post suggesting that Dojo doesn't have validation for Textarea, but in Dojo 1.9, there's an argument 'required'.
I've done the following:
new Textarea({required:true, value:""}, query('[name=description]')[0])
but the effect isn't what I've expected. The texarea has red border always, even if the field wasn't focused (as opposite to, for example, ValidationTextBox). But when I call:
form.validate()
the validation is passed even if the texarea is empty.
Is it possible to get Textare behave the same as in ValidationTextBox, or as for now, the validation for that component is not yet ready and I'd have to write custom version (as in linked post) or wait for next Dojo?
I've done it using mixin of SimpleTextArea and ValidationTextArea:
define(["dojo/_base/declare", "dojo/_base/lang", "dijit/form/SimpleTextarea", "dijit/form/ValidationTextBox"],
function(declare, lang, SimpleTextarea, ValidationTextBox) {
return declare('dijit.form.ValidationTextArea', [SimpleTextarea, ValidationTextBox], {
constructor: function(params){
this.constraints = {};
this.baseClass += ' dijitValidationTextArea';
},
templateString: "<textarea ${!nameAttrSetting} data-dojo-attach-point='focusNode,containerNode,textbox' autocomplete='off'></textarea>"
})
})

The power of Dojo lies in extending it with ease. If you really need the required functionality, then implement it. If you design it well, there should be no problem if it actually gets implemented in a new release of Dojo.
If you really want to know if such a feature exists or is in development I suggest looking at http://bugs.dojotoolkit.org. Besides, you can always contribute to the code, that's what open source is meant for.
I would like to add to the answer of Donaudampfschifffreizeitfahrt
instead of "this.baseClass += ' dijitValidationTextArea';"
I would do
this.baseClass = this.baseClass.replace('dijitTextBox', 'dijitValidationTextArea');
because
• we do not need the TextBox class if we have got a textarea mixin
• ! the "rows" parameter is mixed in but not fired/styled if the TextBox class is present ...
I'm just working on a little webservice. Therefore I am using an AJAX call and append my data to a table on my website. Here I can read and update already existing entries or write new entries. Everything works fine.
I want to have the possibility to update already existing with the wysihtml5 editor. I already integrated this editor on my website and I can use it on new entries. That works, too.
But now there's the problem with existing data. When it comes to the form to update data, I want the existing data being displayed as the value. Everything works fine on all inputs, just the wysihtml5 don't work.
I already know that there's an iframe and that's why I can't set the value of the textarea. I searched for a solution and found the following code (last line):
var editor = new wysihtml5.Editor("textareaid", { // id of textarea element
toolbar: "wysihtml5-toolbar", // id of toolbar element
parserRules: wysihtml5ParserRules, // defined in parser rules set
});
editor.setValue('Here's the content', true);
Usually this should work, but no content appears and the console just tells me:
Error: wysihtml5.Sandbox: Sandbox iframe isn't loaded yet
I tried it with a timeout-function but nothing works. Searching on the internet it also seems that there is noone else with that problem. I hope you can help me out, would be great!
Is there a way to set the value?
This code work for me
$("#product_details").data("wysihtml5").editor.getValue();// to get the value
$("#product_details").data("wysihtml5").editor.setValue('new content')// to set the value
I got the solutions, below code worked for me
$('#id ~ iframe').contents().find('.wysihtml5-editor').html(my_html);
This work for me
$('.wysihtml5-sandbox').contents().find('.wysihtml5-editor').html(my_html);
the ".wysihtml5-sandbox" is a class name of iframe, create by wysihtml5 by default.
I finally got it working by myself. I just change the second parameter of setValue to false. I don't know why, but it works then.
this code worked for me :
var wysihtml5Editor = $('#text_editor').data("wysihtml5").editor;
wysihtml5Editor.setValue("<p>foobar</p>", true);
console.log(wysihtml5Editor.getValue());

I put a Ajax link using the following code:
echo chtml::ajaxLink('GO', 'http://localhost/index.php?r=user/delete', array('method'=>'POST'));
But, regardless of giving the second parameter as URL i,e 'http://localhost/index.php?r=user/delete'. It generates link with the current URL in the browser not the URL I just specified.
What is the issue? How could I create AJAX link? Google several hours but can't solve the issue.
Any kind of help is highly appreciated.
First of all, you should always try and create normalized urls.
But i think your doubt lies in the # that is generated/appended. If you go and check the source of yii ajaxLink you'll see this:
public static function ajaxLink($text,$url,$ajaxOptions=array(),$htmlOptions=array())
{
if(!isset($htmlOptions['href']))
$htmlOptions['href']='#';
$ajaxOptions['url']=$url;
$htmlOptions['ajax']=$ajaxOptions;
self::clientChange('click',$htmlOptions);
return self::tag('a',$htmlOptions,$text);
}
so if you don't set the href property of the a tag in the htmloptions array, the # will be appended.
You should also understand that yii uses jquery, so if you check out the source of the page, you'll see at the bottom, how jquery is used to carry out an ajax request, your actual url that is called will also be seen in that script. So the third option/parameter in ajaxLink is for options for jquery's ajax function. You can create better ajax links using this option.
Regardless of where(which controller) your url points to in your project, the action associated with that url will be called.
So anyway, you can modify your code like this if you want the url to be shown and not a # :
echo CHtml::ajaxLink('GO', 'http://localhost/index.php?r=user/delete',
array('type'=>POST), //there are various other options for jquery ajax
array('href'=>'http://localhost/index.php?r=user/delete'));
To make better ajax links i would suggest going through jquery's ajax documentation. There is an option for a success function, that you can use to let the user know that the operation was completed.
Hope this helps, don't hesitate to leave comments if i haven't answered your question completely.
Have you tried:
echo CHtml::ajaxLink('GO', array('/user/delete'), array('method'=>'POST'));
as the ajaxLink documentation suggests...? Look also at the normalizeUrl method.
Using these methods, which in turn are using createUrl, is usually better since it will take care to create a valid url for your site.
I had the same issue(or maybe similar).
I've used renderPartial to load view and later in that view i was using ajaxLink and it was not working.
What i have found, that when using renderPartial, there was no jquery script for ajax action.
What you have to do is to add 4th argument(true) in renderPartial function to generate jquery script.
See the documentation: http://www.yiiframework.com/doc/api/1.1/CController/#renderPartial-detail
Hope it helps and saves time to figure it out.
