I have a page where I want a user to be able to edit their room information. For example the name of the room. The code I have currently is that it shows the roomName in an h3 and if they click on the edit button, then the property edit is changed to true (this will then show the text-field instead of the h3).
<!-- Room Name -->
<h2 v-if="edit == false">{{ roomName }}</h2>
<!-- EDIT -->
<v-text-field
v-else
label="Room Name"
v-model="roomName"
/>
<!--Edit Button-->
<v-btn v-if="edit == false"
#click="edit = true"
class="filter">Edit</v-btn>
<!--Cancel Button-->
<v-btn v-if="edit == true"
#click="cancelEdit"
class="filter">Cancel</v-btn>
The problem is: That if a user presses cancel I don't want it to update the property roomName. I try to do this by rerunning a computed property that grabs the roomName from the store. However I doesn't allow me to call a computed property in cancelEdit.
The reason I'm using a roomName property & v-model, and not directly using the value from the computed property is... because I don't understand how I can grab the value from an input if I press save.
How can I grab the value from an input or how can I make a cancel button with this structure?

I didn't use vuex but you can your initial values from your store:

I would like a clearable v-text-field with a label to show a computed string property based on other another property (a boolean in this simplified example).
Initially it works, the correct default string value is shown.
If I invert the boolean with a button from outside the v-text-field component, the next correct string value is shown as expected.
But if I use the clear button in the v-text-field to invert the boolean, the v-text-field clears and uses the label in the input field when focus is lost, and therefore not using the expected string value.
Input:
<v-text-field :value="text" label="Just a label" clearable #click:clear="booleanModel = true;"></v-text-field>
Computed property:
text: function() {
if(this.booleanModel) {
return 'Its on'
} else {
return 'Default text';
}
}
As far as I can see via vue dev tools, the state in the v-text-field is the same either way.
How come, and how to avoid this?
Please refer to this example: https://codepen.io/fasterlars/pen/RwKrzXZ?editors=1010
To be honest your use-case seems very strange but...
The problem is that v-text-box has some internal state (according to source code comments to make it work without the model) and on clear icon click it sets it to null but it does this in the nextTick - source. This is little bit strange but they probably has some reasons to do so...
So if you don't want to really clear the content but instead set it to something else, do not use default "clearable" functionality and use append slot instead:
<v-text-field :value="text" label="Just a label">
<template v-slot:append>
<v-icon #click="booleanModel = true">clear</v-icon>
</template>
</v-text-field>
When you click on the clear button, the value of booleanModel does not change.
You need to update the #click:clear = "booleanModel = false;".
Also, add a :key="booleanModel in your text field, which will ensure that whenever the value of booleanModel changes it will re-render the v-text-field component again.
I'm building a list of v-checkboxes using this code
<div class="row form-group" v-for="(author, key) in authorData" :key="key">
<v-layout row wrap>
<v-flex xs1 sm1 md1 text-xs-center>
<div>
<v-checkbox
label
:key="author.PmPubsAuthorID"
v-model="authorData[key].checked"
v-bind:id="author.PmPubsAuthorID.toString()"
color="success"
#change="authorCBClicked(authorData[key])"
></v-checkbox>
</div>
The PmPubsAuthorID is a number like 1047602 and is a sequential number in the entire database, no 2 records are the same. When I run the code to build the list it works fine and shows a checkbox if the value is true. What I am trying to do is when a checkbox is checked in the
authorCBClicked(author) {
//PmPubsAuthorID = 1047602
// alert(author.PmPubsAuthorID + " " );
// author.checked = false; does not work
this.authorData[author.PmPubsAuthorID].checked = false; does not work
this.authorData["1047602"].checked = false; does not work
this.authorData[1047602].checked = false; does not work
this.authorData[2].checked = false; does work
},
As you can see I have tried various ideas and the only one that seems to work is passing in an ordinal but I have no way of knowing that. Do I need to use an index when building the checkboxes?
The reason: I have a checkbox then when checked calls a dialog box that asks " Are you sure you want to "Add this item to the list" if they say yes I want the original checkbox to be checked but if they say no then the original checkbox needs to be false. I have found that if I try to set the checked status of the calling checkbox to false it does not work but works fine once outside that method. I have passed the key and author information to the new dialog and let it change the checkbox to false if needed
Thanks for the help.
Just pass the key instead of the whole item to your method :
#change="authorCBClicked(key)"
and on your method :
authorCBClicked(key) {
this.authorData[key].checked = !this.authorData[key].checked;
}
Or :
you can do it directly on the template :
#change="author.checked = !author.checked"
I am developing the front end through Vue.js and Buefy.
I am using Buefy's Table to sort by a click event on a specific field. Of course, my tables are sorted by creation order by default. (Backend) What I want to do is a temporary alignment that can be done at the front end like now.
Already this is perfect. However, the current column click events will not return to the default sort order (creation order) unless they are refreshed.
I hope you understand my words. If you need additional code or explanation, please do not hesitate to tell us.
Thanks for reading.
I am waiting for your help.
component.vue
<b-table :data="movies">
<template slot-scope="props">
<b-table-column centered="true" field="title" label="title" sortable>
<strong>{{props.row.title}}<strong>
</b-table-column>
<b-table-column centered="true" field="content" label="content" sortable>
<strong>{{props.row.content}}<strong>
</b-table-column>
<template>
</b-table>
Using Vue you can create a button to reload the table (explanation below).
<button #click="resetSortKey = new Date().toLocaleString()">
Clear sorting
</button>
<b-table
:key="resetSortKey"
<!-- ... -->
</btable>
And don't forget to initialize resetSortKey in your data.
data() {
return {
resetSortKey = 0,
// All your other stuff.
}
}
Explanation
We update the value of resetSortKey with a unique value (the date/time) whenever the button is pressed.
We set the key on the table so that it reloads whenever the value of resetSortKey changes. Whenever the table reloads it will clear the sorting and restore the order to the default.
I have created a page with lightening components as shown the below image, I want to change my pick-List field into radio button next to picklist option to choose the appropriate selection, can someone please help to create radio buttons instead of pickList filed
in the component I have used below code
<div class="slds-form-element">
<div class="slds-form-element__control">
<ui:inputSelect label="Race Type"
aura:id="Type"
class="slds-select"
labelClass="slds-form-element__label"
value="{!v.newRace.Race_Type__c}" />
</div>
Maybe something in line with this: (replace v.Name with attribute that contains the name of the race):
<aura:component>
<lightning:radioGroup name="radioGroup"
label="slds-form-element__label"
options="{! v.newRace.Race_Type__c }"
value="{! v.Name}"
type="radio"/>
</aura:component>
Given the following:
<div id="#my-container">
<div class="title">Companies</div>
<div class="tab active tab-apple">Apple</div>
<div class="tab tab-google">Google</div>
</div>
When page is loaded without any tab clicks yet, whichever tab with the default active class, needs to go in the .title div. For the example above, <div class="title">Apple</div>
On click of a tab, the class is switched to active, and vue.js needs to update the .title div once again.
How can this be done with vue.js? I've tried but not able to get it to work as intended.
The answer by David is one way to do it. But Vuejs offers in-line computations for this. So, no need to hook into any CSS event. Here's some code to explain:
Create a data property active_tab, just like David mentioned. And then bind it's value just like he's done it. In your tabs, add an click event and at that event, assign appropriate value to active_tab.
<div class="tab active tab-apple" #click="active_tab = Apple">Apple</div>
<div class="tab tab-google" #click="active_tab = Google">Google</div>
Now, to dynamically assign the active class to the respective tab, make the class attribute, a computed property, like this:
<div
:class="['tab', active_tab == 'Apple' ? 'active' : '', 'tab-apple']"
>
Apple
</div>
What this code is basically doing is, :class makes class a computed property. Then the commas in the array divide the statement. So, the computation will always add tab and tab-apple classes. But, only if active_tab == 'Apple' then ? add 'active' else : add ''
Not sure which CSS framework you are using, but normally I hook into the events thrown by the tab switching (many CSS frameworks provide this access). Once hooked into it, you can write a Vue custom directive that will take that event and use it to update a VM attribute that indicates which tab is active.
Then you can use normal mustache templating to get it into your template:
<div class="title">{{ active_tab }}</div>
