Is it possible to pass a data value from a kendoSwitch?
Simple dojo here: https://dojo.telerik.com/eCUVitEC/2
Code as follows:
<input type="checkbox" id="theSwitch" data-id="MyId" />
<script>
$(function () {
$("#theSwitch").kendoSwitch({
change: function (e) {
alert("checked: " + e.checked);
}
});
});
</script>
This works but what I really want is to pass the data-id, not the checked value. I have tried a number of ways but can't seem to find the right syntax.
Thanks.

Sure.
On change event find attribute in that element:
this.element.attr("data-id");
Example: Get element attribute

So from the backend I get a array of objects that look kind of like this
ItemsToAdd
{
Page: MemberPage
Feature: Search
Text: "Something to explain said feature"
}
So i match these values to enums in the frontend and then on for example the memberpage i do this check
private get itemsForPageFeatures(): ItemsToAdd[] {
return this.items.filter(
(f) =>
f.page== Pages.MemberPage &&
f.feature != null
);
}
What we get from the backend will change a lot over time and is only the same for weeks at most. So I would like to avoid to have to add the components in the template as it will become dead code fast and will become a huge thing to have to just go around and delete dead code. So preferably i would like to add it using a function and then for example for the search feature i would have a ref on the parent like
<SearchBox :ref="Features.Search" />
and in code just add elements where the ItemsToAdd objects Feature property match the ref
is this possible in Vue? things like appendChild and so on doesn't work in Vue but that is the closest thing i can think of to kind of what I want. This function would basically just loop through the itemsForPageFeatures and add the features belonging to the page it is run on.
For another example how the template looks
<template>
<div class="container-fluid mt-3">
<div
class="d-flex flex-row justify-content-between flex-wrap align-items-center"
>
<div class="d-align-self-end">
<SearchBox :ref="Features.Search" />
</div>
</div>
<MessagesFilter
:ref="Features.MessagesFilter"
/>
<DataChart
:ref="Features.DataChart"
/>
So say we got an answer from backend where it contains an object that has a feature property DataChart and another one with Search so now i would want components to be added under the DataChart component and the SearchBox component but not the messagesFilter one as we didnt get that from the backend. But then next week we change in backend so we no longer want to display the Search feature component under searchbox. so we only get the object with DataChart so then it should only render the DataChart one. So the solution would have to work without having to make changes to the frontend everytime we change what we want to display as the backend will only be database configs that dont require releases.
Closest i can come up with is this function that does not work for Vue as appendChild doesnt work there but to help with kind of what i imagine. So the component to be generated is known and will always be the same type of component. It is where it is to be placed that is the dynamic part.
private showTextBoxes() {
this.itemsForPageFeatures.forEach((element) => {
let el = this.$createElement(NewMinorFeatureTextBox, {
props: {
item: element,
},
});
var ref = `${element.feature}`
this.$refs.ref.appendChild(el);
});
}
You can use dynamic components for it. use it like this:
<component v-for="item in itemsForPageFeatures" :is="getComponent(item.Feature)" :key="item.Feature"/>
also inside your script:
export default {
data() {
return {
items: [
{
Page: "MemberPage",
Feature: "Search",
Text: "Something to explain said feature"
}
]
};
},
computed: {
itemsForPageFeatures() {
return this.items.filter(
f =>
f.Page === "MemberPage" &&
f.Feature != null
);
}
},
methods: {
getComponent(feature) {
switch (feature) {
case "Search":
return "search-box";
default:
return "";
}
}
}
};
I want to keep the value of a variable identical with the content of a textarea.
I don't want to use v-bind or v-model, because I have already bound the textarea with another value.
This is a notebook app, and the textarea is used to display the content of a note, so it has been bound using v-bind with a note object, like
<textarea cols="30" rows="3" v-bind:value="note"></textarea>
Now, I want to add the "edit note" functionality. So when the content of the textarea changes, I want to store its value into a variable, and when the "submit" button is clicked, I pass the value of the variable, which contains the new content of the note, to backend to update the note.
My question is, how to store the textarea's content into the variable after each time the content changes?
I think I cannot use v-model because this way the note will be changed right after the content of the textarea is modified (though not sent to backend), but this is not what I want. What I want is the note to be changed only after the "submit" button is clicked. Thus, I cannot use v-model
Should I use v-on:change? If so, how to get the content of the textarea?
Like,
<textarea v-on:change="updateTheVariable(I need to get the content of the textarea here)"> ... </textarea>
methods: {
updateTheVariable(content of the textarea) {
this.variable = content of the textarea
}
}
Thanks
I'm assuming this thing only shows up when you click some kind of edit button which is why you don't want to alter note so try something like this instead
<button type="button" v-if="!editMode" #click="editNote">Edit</button>
<form v-if="editMode" #submit="handleSubmit">
<fieldset :disabled="saving">
<textarea v-model="editingNote"></textarea>
<button type="submit">Edit</button>
</fieldset>
</form>
export default {
data: () => ({
note: 'whatever', // maybe it's a prop, maybe assigned later, doesn't matter
editMode: false,
editingNote: null, // this will be used to bind the edited value
saving: false
}),
methods: {
editNote () {
this.editingNote = this.note
this.editMode = true
this.saving = false
},
async handleSubmit () {
this.saving = true // disables form inputs and buttons
await axios.post('/notes/update', { note: this.editingNote}) // just an example
this.note = this.editingNote // or maybe use data from the response ¯\_(ツ)_/¯
// or if it's a prop, this.$emit('updated', this.editingNote)
this.editMode = false
}
}
}
As #Phil indicated in a deleted post, the right way to do it is
<textarea #input="updateTheVariable($event.target.value)"></textarea>
.
.
.
methods:{
updateTheVariable(value){
this.variable = value
}
}
i'm working on a vue file and have a form :
<div class="input-group">
<span class="input-group-addon">Montant</span>
<input type="number" class="form-control" v-model="amount" v-bind:value="pattern['value']"]>
</div>
my tab pattern is loaded like that :
var request = $.ajax({
url: '{{ path ('home') }}promos/pattern/'+value,
})
request.success(function(data){
if(data['pattern']==='yes'){
this.pattern=data[0];
alert(this.pattern['value']);
}
})
and my instance :
var instance = new Vue({
el: "#General",
data: {
[...]
pattern: []
}
and the request is made evertyime i do 'action a'. I have the right alert with the value i want everytime i do 'action a' but the input stays at 0 and won't dynamically change.
Something is wrong with your code. Firstly, let's look at your ajax request:
request.success(function(data){
if(data['pattern']==='yes'){
this.pattern=data[0];
alert(this.pattern['value']);
}
})
What is the form of your data response? Because you are checking something with data['pattern'], and then you are trying to associate to this.pattern something that you call data[0]
Then, as stated in #thanksd answer, you are referencing a wrong this in your ajax callback, you need to create a self variable:
var self = this
var request = $.ajax({
url: '{{ path ('home') }}promos/pattern/'+value,
})
request.success(function(data){
if(data['pattern']==='yes'){
self.pattern=data[0];
alert(this.pattern['value']);
}
})
Finally, you write:
<input type="number" class="form-control" v-model="amount" v-bind:value="pattern['value']"]>
So there are a few mistakes here. Firstly, you have a ] at the end of the line that has nothing to do here.
Secondly, you are using v-bind:value, this is not something that is going to be responsive. If you want this input to be responsive, you should use v-model and set the value of amount when you want to change the input value.
Hope this helps
Three things:
The this in your success handler is not referencing the Vue instance. You need to set a reference outside the scope of the handler and use that instead.
You can't chain a success callback to jQuery's ajax method in the first place. It's defined as a property in the parameter object passed to the call. (Maybe you copied code over wrong?)
You need to get rid of v-model="amount" if you want the input's value to reflect the value bound by v-bind:value="pattern"
Your code should look like this:
let self = this; // set a reference to the Vue instance outside the callback scope
var request = $.ajax({
url: '{{ path ('home') }}promos/pattern/'+value,
success: function(data) { // success handler should go in the parameter object
if (data['pattern']==='yes') {
self.pattern=data[0];
alert(this.pattern['value']);
}
}
})
Neither works this one:
$formTemplateModal.modal('show');
$('#form_template_name').focus();
nor a more complicated one:
$formTemplateModal.modal('show').promise().done(function() {
// #todo: does not work.
$('#form_template_name').focus();
});
field $('#form_template_name') is a input[type=text] and it surely exists and it belongs to $formTemplateModal.
The shown is changed in bootstrap 3 ,
Try this if it could help
$('#myModal').on('shown.bs.modal', function () {
$('#textareaID').focus();
})
this is more easier try using the autofocus in your tag .
<textarea id="textareaID" autofocus="" ></textarea>
UPDATE:
Let me rephrase.
I have multiple divs that all contain, among other things, an img element with the class="yes". But they're not all the same siblings.
Two examples:
<div id="div1" onclick="function(this)">
<img src="image1" />
<div>
<img src="image2" class="yes" />
</div>
</div>
<div id="div2" onclick="function(this)">
<img src="image3" class="yes" />
</div>
Now I'm trying to formulate one function for both divs that would change the source of the image with class yes.
getElementsByTagName doesn't seem to do the trick, nor does getElementsbyClassName.
Any thoughts? Thanks again!
getElementsByTagname is the wrong function.
There is no easy way to do what you're trying to do, unless you resort to third party libraries such as jQuery.
With jquery, you use this code:
$('img.yes').each(function() {
console.log(this);
});
Here is a working example of what you're trying to do: http://jsfiddle.net/ZYBp6/
You can use jQuery like this:
function some_function(x)
{
var arr = $("#" + x.id + " .yes"); // Gets all children of the class "yes"
}
Or if you only want to get img elements, you can do this instead:
function some_function(x)
{
var arr = $("#" + x.id + "img.yes");
}
In both of these examples, arr would contain DOM elements, and not the kind of "element" produced by jQuery normally.
This seems to work:
function function(x) {
$(x).find('.yes').attr('src','differentimage.png');
}
