event.trigger is not working only in the following case.
js file:
alert(event.target.getAttribute("name"));
html file:
<div class=" tile tile-big tile-5" id="three" name = "Launch" >
<div><p>Launch Application </p></div>
</div>
it is giving "null", not name.
and
alert(document.getElementById(this.id).getAttribute("name")); is working fine.
help me.
Thanks in advance.
the problem is your target is not
<div class=" tile tile-big tile-5" id="three" name = "Launch" >
but
<p>Launch Application </p>
which does not have "name" attribute that is why you get null
try to add name attribute to it and you will get right alert.
try this
<div class=" tile tile-big tile-5" id="three" name = "Launch" onclick="testAlert(event)">
<div name = "Launch2"><p name = "Launch3">Launch Application </p></div>
</div>
<script>
function testAlert(event)
{
var target = event.target || event.srcElement;
alert(target.getAttribute('name'));
}
</script>
you will get the answer

I am trying to perform concatenation in img tag and here below is what i am trying to do:
<div class="vx-row">
<div v-for="item in items" class="vx-col" v-bind:key="item.id">
<div class="w-full mb-base">
<vx-card>
...
<img :src="require('./img/stars_' + item.id + '_logo.png')" alt=""/>
...
</vx-card>
</div>
</div>
</div>
I am trying to concatenate the item.id to the image path as i am making my code dynamic such that when the cards are displayed then the respective image is displayed.
Please let me know how it can be done, initially i could see images in respective cards but then i tried using
<img :src="require(`./img/stars_${this.$route.params.item_id}_logo.png`)">
in other components then i get error every where.
Here is the error that i get everywhere:
Here you can try a shorthand that webpack will use.
HTML:
<img :src="getByPath(item.id)" v-bind:alt="item.id">
Method:
getByPath(id) {
return require('./img/stars_' + id + '_logo.png')
}
you can do with method like below code
try this:
<div class="vx-row">
<div v-for="item in items" class="vx-col" v-bind:key="item.id">
<div class="w-full mb-base">
<vx-card>
...
<img :src="getImgUrl(item.id)" alt=""/>
...
</vx-card>
</div>
</div>
</div>
and create method:
getImgUrl(value) {
return `./img/stars_${value}_logo.png`
},
I created a simple real-time chat application using vue js in laravel.
I am having a problem with the automatic scroll of the div when there is a new data.
What I want is the div to automatically scroll down to the bottom of the div when there is a new data.
Here is my code so far.
Chat.vue file
<template>
<div class="panel-block">
<div class="chat" v-if="chats.length != 0" style="height: 400px;" id="myDiv">
<div v-for="chat in chats" style="overflow: auto;" >
<div class="chat-right" v-if="chat.user_id == userid">
{{ chat.chat }}
</div>
<div class="chat-left" v-else>
{{ chat.chat}}
</div>
</div>
</div>
<div v-else class="no-message">
<br><br><br><br><br>
There are no messages
</div>
<chat-composer v-bind:userid="userid" v-bind:chats="chats" v-bind:adminid="adminid"></chat-composer>
</div>
</template>
<script>
export default {
props: ['chats','userid','adminid'],
}
</script>
ChatComposer.vue file
<template>
<div class="panel-block field">
<div class="input-group">
<input type="text" class="form-control" v-on:keyup.enter="sendChat" v-model="chat">
<span class="input-group-btn">
<button class="btn btn-primary" type="button" v-on:click="sendChat">Send Chat</button>
</span>
</div>
</div>
</template>
<script>
export default{
props: ['chats','userid','adminid'],
data() {
return{
chat: ''
}
},
methods: {
sendChat: function(e) {
if(this.chat != ''){
var data = {
chat: this.chat,
admin_id: this.adminid,
user_id: this.userid
}
this.chat = '';
axios.post('/chat/sendChat', data).then((response) => {
this.chats.push(data)
})
this.scrollToEnd();
}
},
scrollToEnd: function() {
var container = this.$el.querySelector("#myDiv");
container.scrollTop = container.scrollHeight;
}
}
}
</script>
I am passing a div id from the Chat.vue file to the ChatComposer.vue file.
As you can see in the ChatComposer.vue file there is a function called scrollToEnd where in it gets the height of the div id from Chat.vue file.
When the sendchat function is triggered i called the scrollToEnd function.
I guess hes not getting the value from the div id because I am getting an error - Cannot read property 'scrollHeight' of null.
Any help would be appreciated.
Thanks in advance.
the scope of this.$el.querySelector will be limited to only ChatComposer.vue hence child component can not able to access div of parent component #myDiv .
You can trigger event as below in ChatComposer
this.$emit('scroll');
In parent component write ScollToEnd method and use $ref to assign new height
<chat-composer v-bind:userid="userid" v-bind:chats="chats" v-bind:adminid="adminid" #scroll="ScollToEnd"></chat-composer>

I am using Knockoutjs to render a user profile page. For which I am calling a Web API service which returns User details with its Profile Picture.
var MessageFrom = {
FromUserProfileId: self.FromUserProfileId,
FromUserName: self.FromUserName,
FromUserPictURL: self.FromUserPictURL
}
<div id="comments" class="comments" data-bind="with: viewModel">
<div class="comment clearfix" data-bind="foreach: Messages">
<div class="comment-avatar">
<img class="img-circle" data-bind="attr:{'src': FromUserPictURL}" alt="avatar">
</div>
<header>
<h3 data-bind="text: FromUserName"></h3>
<div class="comment-meta"><p data-bind="text: moment(DatePosted).format('LLL')"></p> </div>
</header>
<div class="comment-content">
<div class="comment-body clearfix">
<p data-bind="text: MessageBody"></p>
</div>
</div>
</div>
</div>
The URL of the Image returned from WebAPI is Relative URL like ~/Content/Member/Image1.jpg. While its bind with Image URL shows like "http://sitename.com/profile/~/Content/Member/Image1.jpg".
Everything works great accept Profile Picture
I need to work something on binding as as I cannot change the Path coming from Database.
Appreciate your suggestions.
Regards,
Your binding looks okay. For starters I would use your IE or Chrome developer tools ( F12 ) and change the src manually of the image to find out what exactly works for you.
You say you recieve this: ~/Content/Member/Image1.jpg
Setting the src to this should work: /Content/Member/Image1.jpg
You can change your message object client-side like this, once you're sure what is needed, but I think this should suffice:
var MessageFrom = {
FromUserProfileId: self.FromUserProfileId,
FromUserName: self.FromUserName,
FromUserPictURL: self.FromUserPictURL.replace('~','')
}
I found this voting script online and was wondering instead of a onclick alert(You already voted) can i change it to a popup message that i can style with css... i have only submitted a part of the code if you need to see more let me know. thanks in advance
function addVotData(elm_id, vote, nvotes, renot) {
// exists elm_id stored in ivotings
if(ivotings[elm_id]) {
// sets to add "onclick" for vote up (plus), if renot is 0
var clik_up = (renot == 0) ? ' onclick="addVote(this, 1)"' : ' onclick="<a type="button" class="btn" style="width:100%;" href="#test_modal" data-toggle="modal">alert</a>"';
// if vot_plus, add code with <img> 'votplus', else, if vot_updown1/2, add code with <img> 'votup', 'votdown'
if(ivotings[elm_id].className == 'vot_plus') { // simple vote
ivotings[elm_id].innerHTML = '<h6>'+ vote+ '</h6><span><img src="'+votingfiles+'arrow.png" alt="1" title="vote"'+ clik_up+ '/></span>';
};
}
}
You can use Bootstrap modal pop up instead of alert.
This is well explained example
If you need more help let me know
Update

What is the proper way to edit items in a listview when using Kendo UI Mobile & MVVM?
I don't get the expected results when using the following:
HTML
<div id="itemsView"
data-role="view"
data-model="vm">
<ul data-role="listview" data-bind="source: items"
data-template="itemsTemplate">
</ul>
<script id="itemsTemplate" type="text/x-kendo-template">
<li>
#=Name#
</li>
</script>
<input type="text" data-bind="value: newValue" />
<button data-role="button" data-bind="click: update">update</button>
</div>
JavaScript
var vm = kendo.observable({
items: [{
Name: "Item1"}],
newValue: '',
update: function(e) {
var item = this.get("items")[0];
item.set("Name", this.get("newValue"));
//adding the follwoing line makes it work as expected
kendo.bind($('#itemsView'), vm);
}
});
kendoApp = new kendo.mobile.Application(document.body, {
transition: "slide"});
I expect the listview to reflect the change to the Name property of that item. Instead, a new item is added to the listview. Examining the array reveals that there is no additional item, and that the change was made. (re)Binding the view to the view-model updates the list to reflect the change. Re-Binding after a change like this doesn't seem to make any sense.
Here is the jsfiddle:
http://jsfiddle.net/5aCYp/2/
Not sure if I understand your question properly: but this is how I did something similar with Kendo Web UI, I expect mobile is not so different from Web UI from API perspective.
$element.kendoListView({
dataSource: list,
template: idt,
editTemplate: iet,
autoBind: true
});
The way I bind the listview is different, but I guess you can get similar results with your method as well.
I pass two templates to the list view, one for displaying and one for editing.
Display template contains a button (or any element) with css class k-edit to which kendo will automatically bind the listview edit action.
display template:
<div class="item">
# if (city) { #
#: city #<br />
# } #
# if (postCode) { #
#: postCode #<br />
# } #
<div class="btn">
<span class="k-icon k-edit"></span>Edit
<span class="k-icon k-delete"></span>Delete
</div>
</div>
Edit template
<div class="item editable">
<div>City</div>
<div>
<input type="text" data-bind="value: city" name="city" required="required" validationmessage="*" />
<span data-for="city" class="k-invalid-msg"></span>
</div>
<div>Post Code</div>
<div>
<input type="text" data-bind="value: postCode" name="postCode" required="required" validationmessage="*" />
<span data-for="postCode" class="k-invalid-msg"></span>
</div>
<div class="btn">
<span class="k-icon k-update"></span>Save
<span class="k-icon k-cancel"></span>Cancel
</div>
</div>
Clicking that element will put the current element on edit mode using the editTemplate.
Then on the editTemplate there is another button with k-update class, again to which kendo will automatically bind and call the save method on the data source.
Hopefully this will give you more ideas on how to solve your issue.
The problem was caused by the <li> in the template. The widget already supplies the <li> so the additional <li> messes up the rendering. This question was answered by Petyo in the kendo ui forums
