I want to implement a suggestion combobox which shows suggestions grabbed from my own web service (using restapi and jsonp). I found that ComboBox.store.root.children contains suggestion's data and wrote the code below. For the simplicity I use there array instead of getting suggestions from my service.
The problem with that is it looks like a hack and some features don't work properly. For instance, I can't get rid of 'Search' phrase in the list.
Can you suggest more elegant solution?

I want to assign a value to hidden input then grab that value from next section of javascript using input id. So it will alert the value as per hidden input value which assigned from the first section of javascript. However, it looks not useful this is important for my current task. I have to push value to HTML then get it back again in javascript variable. Let me know if you have any solution.

You can use $(document).ready() method which waits until all DOM elements are rendered. Then executes the JS code. You can read more about it here

Using HTMLFormControlsCollection of the Web API allows us to reference any and all form elements very easily:
Example
/* Find the first form of a page without knowing it's .class or #id */
// HTMLFormControlsCollection // Common way
var form = document.forms[0]; var form = document.getElementsByTagName('form')[0];
Demo
<!DOCTYPE html>
<html>
<head>
<title>Just test</title>
</head>
<body>
<form id='A'>
<input id="X" name="X">
<output id='Y' name='Y'></output>
<input id='Z' name='Z' type='hidden'>
</form>
<script>
var F = document.forms.A;
F.oninput = function() {
var X = F.X.value;
var Y = F.Y;
var Z = F.Z;
Y.value = X;
Z.value = X;
}

I have used nicEditor in my winforms by loading a web browser and loading the nicEditor inside it. By default when the editor loaded and after that I click in the middle of the editor the focus doe not go to nicEditor. But if I click right at the start of the editor, focus is set to the editor. Following is my HTML file code.
<html>
<head>
<script type="text/javascript">
var myInstance = "";
function GetContent() {
//window.alert(""+myInstance);
//var content = tinyMCE.get('tinyMceEditor').getContent();
//content = content.replace("<body>", "<body style=\"font-size:10px;\">");
//var content = nicEditors.get('area3').getContent();
var content = myInstance.instanceById('editor').getContent();
//window.alert(myInstance.instanceById('editor').getContent());
return content;
}
function SetContent(htmlContent) {
setTimeout(function () {
//window.alert(htmlContent);
//nicEditors.get('area3').setContent(htmlContent);
myInstance.instanceById('editor').setContent(htmlContent);
if (htmlContent == undefined || htmlContent == '')
myInstance.instanceById('editor').setContent('');
//tinyMCE.get('tinyMceEditor').readOnly = true;
}, 100);
}

<script type="text/javascript">
bkLib.onDomLoaded(function () {
//myInstance = new nicEditor().panelInstance('editor');
myInstance = new nicEditor({ maxHeight: 388 }).panelInstance('editor');
//nicEditors.allTextAreas()
});
</script>
here is my simple HTML . Now let me know what exactly you want to do .

I am trying to implement CSS binding in knockoutJS.
I want to print all the names in the names array, One after another.
The catch is that there is another array which has some special names.
All the special names should get "good" CSS class. And the rest, "bad" css class.
Here is something that i have tried:
HTML
<!DOCTYPE html>

<div data-bind="text: $data, css: checkName($data)" ></div>
</div>
</body>
</html>
JAVASCRIPT
var dataModel = function(){
self.items = ko.observableArray(["don","bom","harry","sharry","ron"]);
self.names = ["ron","harry"];
self.checkName = ko.observable(function(name){
if( $.inArray(name,self.names) ){
return "good";
}
else{
return "bad";
}
});
};
ko.applyBindings(new dataModel());
FIDDLE - http://jsbin.com/difaluwo/2/edit
Now its not woking. In console its giving me "Script error. (line 0)"
Thanks !
The out of the box CSS binding is a little tricky. You specify class name and then the condition when it will be applied.
JSBIN
<div data-bind="foreach : items">
<div data-bind="text: $data, css: { good: isGoodName($data), bad: !isGoodName($data) }" ></div>
</div>
And your view model:
var dataModel = function(){
self.items = ko.observableArray(["don","bom","harry","sharry","ron"]);
self.names = ["ron","harry"];
self.isGoodName = function (name) {
return $.inArray(name, self.names) !== -1;
};
};
ko.applyBindings(new dataModel());
I have following code where I am trying to load values into a dropdown from an array(from file page students.js):
student.js
var STU_NAME = 0;
var STU_ID = 1;
var STU_AGE = 2;
var STUDENTS = [
["Apple", 1, 15],
["Billy", 2, 16]
["Cathy", 3, 14]
];
Functions.js
var jQ = $.noConflict();
function populateStudents() {
jQ('#students').empty();
jQ('#students').append(jQ("<option></option>").attr("value", "").text("-- Please Select --"));
for (var _i = 0; _i < students.length; _i++) {
jQ('#students').append(jQ("<option></option>").attr("value", _i).text(STUDENTS[_i][STU_NAME]));
}
}
jQ(document).ready(function () {
populateStudents();
});

You have forgotten to add the jquery library
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js" type="text/javascript"></script>
<script src="../Scripts/Functions.js" type="text/javascript"></script>
<script src="../Scripts/student.js" type="text/javascript"></script>
It is highly recommended to use CDN version of jquery to improve pagespeed,check this link
You need to include jquery library, you can download from here Add the script tag in head of page or before you use jquery.
<head runat="server">
<title></title>
<style type="text/css">
