I've created a simple "helloworld" web component, in that I put a "button" tag and I want that button to be clicked by triggering it but i'm unable to trigger it. What am I doing wrong?
Here is my code for "Index.html" file in which i've called my Own component and values for my button:
<!doctype html>
<html>
<head>
<title>First Polymer component</title>
<script src="bower_components/webcomponentsjs/webcomponents-lite.min.js"></script>
<script src="bower_components/lib/jquery-1.11.2.js"></script>
<link rel="stylesheet" type="text/css" href="bootstrap_theme/css/bootstrap.css" />
<link rel="stylesheet" type="text/css" href="bootstrap_theme/css/bootstrap-theme.css" />
<script src="bootstrap_theme/js/bootstrap.js"></script>
<link rel="import" href="hello-world.html">
<script>
var button_data = [{
"name": "litrary vocabulary",
"span_id": "mostbasic",
"description": "This is a sample description about litrary vocabulary"
}, {
"name": "no contractions",
"description": "This is a sample description about no contractions"
}];
window.addEventListener('WebComponentsReady', function(e) {
var element = document.querySelector('hello-world');
element.buttonsdata = button_data;
});
</script>
</head>
<body>
<hello-world> </hello-world>
<script>
$('.answerButtons').trigger("click");
function k12() {
window.open("http://www.w3schools.com");
}
</script>
</body>
</html>
And the 2nd file contain code for my web component:
<link rel="import" href="bower_components/polymer/polymer.html">
<dom-module id="hello-world">
<style>
p {
color: red;
}
</style>
<template>
<template is="dom-repeat" items="{{buttonsdata}}" as="button_data">
<button type="button" class="btn btn-info answerButtons" onclick = "k12()">{{_getButtonName(button_data)}} </button>
</template>
<p>This is my first own component </p>
<p>This is my first ....... </p>
<p>Kumaran is IDIOT </p>
</template>
<script>
Polymer({
is: 'hello-world',
_getButtonName: function(buttondata) {
return buttondata.name;
}
});
</script>
</dom-module>
button_data should be a property in hello-world
onclick should be on-click for Polymer binding https://www.polymer-project.org/1.0/docs/devguide/events.html

What I want to achieve:
highlight some text in p element
(not add/ or remove) paper-badge when value is 0
change paper-badge color depending on number
Sample module to play with:
<link rel="import" href="https://polygit2.appspot.com/components/polymer/polymer.html">
<link rel="import" href="https://polygit2.appspot.com/components/iron-icons/communication-icons.html">

<template is="dom-repeat" items="{{numbers}}">
<p>color one of my letters</p>
<paper-icon-button id="someid{{index}}" icon="communication:email"></paper-icon-button>
<paper-badge for="someid{{index}}" label="{{item}}"> </paper-badge>
</template>
</template>
<script>
Polymer({
is: "question-one",
properties: {
numbers: {
type: Array,
value: function () {
return [0, 1, 2, 0, 4, 5, 0, 7, 8, 0]
}
}
}
}); </script>
</dom-module>
and usage:
<!DOCTYPE html>
<html lang="en">
<head>
<script src="https://polygit2.appspot.com/components/webcomponentsjs/webcomponents-lite.js"></script>
<link rel="import" href="questions//question-one.html" />
</head>
<body>
<question-one></question-one>
</body>
</html>
Add an id attribute
<p id="someId">
use the $ map to get a reference to the element
this.$.someId.innerText...
this.$ doesn't work for dynamically added HTML or HTML inside template is="dom-if" ortemplate is="dom-repeat" or similar.
For such cases you can use this.$$(selector) where all CSS selectors are supported, while this.$... only supports id (without #)
'my-layout' code :

If I add paper-drawer=toogle attribute, paper-icon-button in main drawer is disappear...
'main.jsp' code:
<%# page language="java" contentType="text/html; charset=EUC-KR"

<m-layout></m-layout>

</html>
If paper-drawer-toggle attribute remove and main.jsp run, I can see icon-button but toggle is not working..
I can't found reference about paper-drawer-panel toggle and behavior.....
What should I do to toggle paper-drawer-panel?
There are a few things I noticed in your code.
In your my-layout code you should also be importing polymer.html
Which version of Polymer are you using? Since you are using the webcomponents-lite.min.js and the title states Polymer 1.0, I am assuming you are using 1.0. In Polymer 1.0 elements are defined using <dom-module id="m-layout"> instead of <polymer-element name="m-layout">
the toggle function in your script is not necessary, the toggle works out of the box using the paper-drawer-toggle attribute on the paper-icon-button element.
I am not sure of your directory structure but the following code works for me. I am assuming you have bower_components (including all polymer, iron, and paper elements) inside of your root. Also in your root I am assuming you have an elements directory containing your m-layout.html file.
You should check your developer tools in your browser to check that all your resources are loading correctly and there are no errors. If so, then your import paths to the components are wrong.
In your elements/m-layout.html:
<link rel="import" href="../bower_components/iron-icons/iron-icons.html" >
<link rel="import" href="../bower_components/paper-icon-button/paper-icon-button.html" >
<link rel="import" href="../bower_components/paper-drawer-panel/paper-drawer-panel.html" >
<link rel="import" href="../bower_components/paper-header-panel/paper-header-panel.html" >
<link rel="import" href="../bower_components/paper-toolbar/paper-toolbar.html" >
<link rel="import" href="../bower_components/polymer/polymer.html">
<dom-module id="m-layout" >
<template>
<paper-drawer-panel>
<paper-header-panel drawer>
<paper-toolbar>
<div>Application</div>
</paper-toolbar>
<div> Drawer content... </div>
</paper-header-panel>
<paper-header-panel main>
<paper-toolbar>
<paper-icon-button icon="menu" style="color: white;" paper-drawer-toggle></paper-icon-button>
<div>Title</div>
</paper-toolbar>
<div> Main content... </div>
</paper-header-panel>
</paper-drawer-panel>
</template>
</dom-module>
<script>
Polymer({
is: 'm-layout'
// this is not needed
//togglePanel: function() {
// this.$.paper_drawer_panel.togglePanel();
//}
});
</script>
and this in main.jsp:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, minimum-scale=1.0, initial-scale=1.0, user-scalable=yes">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes">
<title>My Test</title>
<!-- Load platform support before any code that touches the DOM. -->
<script src="bower_components/webcomponentsjs/webcomponents-lite.min.js"></script>
<link rel="import" href="elements/m-layout.html">
</head>
<body>
<m-layout></m-layout>
</body>
</html>
Also keep in mind, that the drawer (and therefore the toggle) is only activated when the screen is very small (mobile). To force the drawer behavior no matter what the screen size, you can force the narrow view by setting the force-narrow attribute: <paper-drawer-panel force-narrow="true">. Alternatively you can set the width at which the drawer should be activated, <paper-drawer-panel responsive-width="800px">.

<paper-header-panel main>
<paper-toolbar class="teal-500">
<paper-icon-button icon="menu" on-tap="menuToggle"></paper-icon-button>
<div class="title">{{toolBarTitle}}</div>
<paper-icon-button icon="search"></paper-icon-button>
</paper-toolbar>
</paper-header-panel>
</paper-drawer-panel>
</template>
<script>
Polymer({
is: "layout-inbox",
menuToggle: function() {
if (this.$.drawer.narrow && this.$.drawer.getBoundingClientRect().width < parseInt(this.$.drawer.responsiveWidth)) {
this.$.drawer.togglePanel();
} else {
this.$.drawer.forceNarrow = !this.$.drawer.forceNarrow;
}
},
properties: {
toolBarTitle: {
type: String,
value: "lucok"
}
}
});
</script>
</dom-module>
I think your code is working. The paper-drawer-toggle attribute is used to tell the browser to show the menu icon when the screen with is narrow. When you size the screen to a small enough width, you should seen the menu icon appear.
Maybe did you just miss the correct DocType in the head of main.jsp
<!DOCTYPE html>
Is there a way for codemirror to highlight the code matching a pattern (like if I use the search addon) when the page load? So I could load the page with ?search=my_pattern and pass the pattern to codemirror.
Here's a sample code and a jsfiddle. You can use CTRL+F to use the search addon.

I figured out how to do it using overlay.js by looking at the CodeMirror: Overlay Parser Demo.

I'm trying to use autocomplete inside a jstree but can't figure out why it doesn't work when both bindings are done in document ready. It works if the autocomplete binding is done after the jstree binding via windows load or a user triggered script.
This is a simplified example of the issue. (code at JSFiddle)

I would like to append some code to a page using jQuery/jQuery mobile,
but I am tripping up on some of the page() and pageshow and refresh methods.
Here is my code. you can cut, paste and run as is.
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0b2/jquery.mobile-1.0b2.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0b2/jquery.mobile-1.0b2.min.js"></script>
<script>
//$(document).ready(function() // get error when I use this
$('div').live('pageshow', function () {
function fnCreateGroups(){
var section = "<p>and add a whole bunch of html code...</p>";
myClone = $(section);
alert((myClone).html()); // this works
myClone.appendTo("#placeholder").page(); // but not appending
}
fnCreateGroups();
});
</script>
</head>
<body>
<div data-role="page">
<div id="placeholder">
<div data-role="content">
<div id="placeholder">this is a small amount of html code.</div>
</div>
</div>
</div>
</body>
</html>
Beta2 release notes:
http://jquerymobile.com/blog/2011/08/03/jquery-mobile-beta-2-released/
instead of:
myClone.appendTo("#placeholder").page();
try
myClone.appendTo("#placeholder").trigger('create');
From your comment:
You are running the live() on all div's
$('div').live('pageshow', function ()
try using the page id instead
$('#change_this_page_only').live('pageshow', function ()
and this:
<div data-role="page">
to something like this:
<div data-role="page" id="change_this_page_only">
