How do I modify the interval speed? - carousel

This question is for this component: https://ant.design/components/carousel/#header
I have attempted autoplayInterval={1000} to no success.

autoPlaySpeed is the prop that you want. You can set autoPlaySpeed={1000}, default value is 3000ms. The carousel component demo uses 'react-slick' and here is the reference for autoPlaySpeed, you can also check rest of additional API's for this plugin. Check this code snippet.

Initially hide first group in Vue-Formulate repeatable group

I'm using Vue-Formulate's Repeatable Groups. For my requirements:
A group is optional to add
If a button is pressed to add a group, then the fields in the group must be validated
The form should not initially show the group; it should show the button to add a group
For example, the desired initial appearance is in the following screenshot, which I generated after clicking the "remove" / X button in the linked codesandbox:
I've mocked this up at codesandbox here: Vue Formulate Group with Button to Start
Is this possible? If so, how?
May 2021 UPDATED WORKAROUND
In #braid/vue-formulate#2.5.2, the workaround below (in Research: A hack that seems to UPDATE: USED TO work) no longer works, using a slot to override the close button, save a ref, and trigger a click does. See also the related feature request at https://github.com/wearebraid/vue-formulate/issues/425.
<script>
export default {
// ... fluff omitted
async mounted() {
await this.$nextTick();
if (!this.hasMessages) {
// See also feature request at https://github.com/wearebraid/vue-formulate/issues/425
this.$refs.closeButton.click();
}
},
};
</script>
<template>
<FormulateInput
type="group"
name="rangeMessages"
:minimum="0"
repeatable>
<!-- See https://vueformulate.com/guide/inputs/types/group/#slots -->
<template #remove="{removeItem}">
<button ref="closeButton" #click.prevent="removeItem"/>
</template>
</FormulateInput>
</template>
Research - Vue-Formulate's Docs
In Vue-Formulate's docs on input with type="group"'s props and slots, there is a minimum prop. I've set that to zero, but that doesn't change the initial appearance. I do see multiple slots, but I'm not quite sure which one to use or if I could use any of them to achieve what I want; it seems like default, grouping, and repeatable might be useful in preventing the initial display of the first group.
Research - Vue-Formulate's Tests
I see that FormulateInputGroup.test.js tests that it('repeats the default slot when adding more', so the default slot is the content that gets repeated. According to the docs, the default slot also receives the index as a slot prop, so that could be useful.
Research - Vue Debugger
The item which I want to initially remove is at FormulateInputGroup > FormulateGrouping > FormulateRepeatableProvider > FormulateRepeatable > FormulateInput:
When I remove the initial item to match the desired initial layout, the group hierarchy changes to:
<FormulateInput><!-- the input type="group" -->
<FormulateInputGroup>
<FormulateGrouping/>
<FormulateAddMore>...</FormulateAddMore>
</FormulateInputGroup>
</FormulateInput>
Based on this change, I would expect that I need to modify FormulateGrouping to get the desired initial appearance, but I haven't found in the source what items are available to me there.
Research: A hack that seems to UPDATE: USED TO work
This hack worked in v2.4.5, but as of 2.5.2, it no longer works. See top of post for an updated workaround.
In the mounted hook, when I first render the form, I can introspect
into the formValues passed to v-model to see if the group lacks an
initial elements that is filled out. If so, then I can make use of a
ref msgs on the FormulateInput of type group to then call
this.$refs.msgs.$children[0].$children[0].removeItem(), which
triggers an initial remove of the (empty) item. This is super hacky,
so I'd prefer a better way, but it kind of works. The only problem is
that it validates the fields when clicking on the button, before any
input has been entered.
This is a fair question, and Vue Formulate used to support the behavior of just using an empty array to begin with, however it became clear that it was confusing to users that their fields would not show up without an empty object [{}] when they bound the model, so a change was made to consider an initial value of an empty array an "empty" field and pre-hydrate it with a value. Once that initial hydration is completed however, you can easily re-assign it back to an empty array and you're good to go. This is easily done in the mounted lifecycle hook:
...
async mounted () {
await this.$nextTick()
this.formData.groupData = []
}
...
Here's a fork of your code sandbox: https://codesandbox.io/s/vue-formulate-group-with-button-to-start-forked-32jly?file=/src/components/Reproduction.vue
Provided solutions weren't working for me but thanks to previous answer I've managed to find this one:
mounted(){
Vue.set(this.formData, "groupData", [])
},
which does same effect as
data(){
formData: {
groupData: [],
},
},
mounted(){
this.formData.groupData = []
},

Vue: My initial data value is not accessible when used as a function param

I am having an issue when triggering the click handler in my button here. The error comes back as TypeError: Cannot read property 'discountProduct' of null when I click the button. I know for a fact that this.discountProduct.id has a value by inspecting it from the Vue Tools and by knowing that the button is rendering to begin with since it only conditionally shows if the id > 1.
I alternatively tried to remove this but it still throws the same error.
I also tried manually just inserting the product id as the param and that works so I am not sure what the issue is at this point.
<button v-if="this.discountProduct.id >= 1"
type="button"
v-on:click="addToCart(this.discountProduct.id, true)"
Is you button in the <template> tags?
If so, you do not need to use this delete from the click argument and v-if. However that should only throw a warning.
Can you also post the code for the method addToCart?
If you are not setting the full discountProduct object you will need to make sure setting the id is reactive. Like the example below:
this.$set(this.discountProduct, 'id', 1)
Nested Object/keys are not reactive without using $set. See https://v2.vuejs.org/v2/guide/reactivity.html for more details.
Hope this helps

Add target blank to a link in a props in Vue.js

I use the ReadMore plugin to crop articles in a page. The plugin provides a props to redirect to a http link when the "read more" is clicked. But I need to display the link in a new tab. The props receives the link in a string.
I tried several ways to add the target blank attribute to this string before passing it to the props. With no success. Like:
http://www.example.com/page-to-see.html target=_"blank"
I used it with or without quotes but in any case, the link works but the attribute is skipped.
Is there a way to intercept this and add a target blank later?
I saw in other questions the use of router-link but I don't know how to manipulate the props content in the first place.
Any clue would be warmly welcomed
Edit: adding more code to give a clearer explanation of the problem I try to solve:
In the template:
<read-more more-str="read more" :text="dwId.texte" :link="dwId.link" less-str="less" :max-chars="540"></read-more>
I get the values from a DB with Axios. The props are specified by the plugin documentation.
The :link must be a string and it's what it gets from the DB. It works. But as I explained, I need to open in a new tab.
Edit: what I tried:
I try to make a computed property that would add the target blank to a string and use it in the read-more props:
computed: {
target: function() {
return this.dwIds.filter((dwId) => {
return dwId.link + target="_blank"
});
},
}
I have two issues here: first , the result is an object and the props requires a string. Furthermore, the way I add the target blank is not correct but I can't find the right syntax yet.
You need to use it as a directive, and override parts of the initial element you're passing. Otherwise there is no way to "intercept" it. Here's the code to the "component" version that won't do the trick for you.

In Dojo how can we set a selected dropdown option?

i am using dropdown widget in dojo (dijit), i want to set the selected option the top menu
i tried this code:
dijit.byId('projectId').addOption({ label: item.projname , value: item.projid, selected:true });
here the selected: true
is not working
Thanks
The asker's code is not correct as the selected property applies for the construction of the object. As PaulR suggested, the asker should use dijit.byId('projectId').set("value",item.projid); when the select widget has already been created.
Aside: I would suggest using the AMD module "dijit/registry" rather than the root dijit object.
According to the documentation, "selected: true" is the correct way to specify the selected item. See https://dojotoolkit.org/reference-guide/1.9/dijit/form/Select.html.
I noticed the same issue in the past, and noticed that this only works correctly when an option has a value. So, can you check if "item.projid" contains a value?

Dojo attach point / byId returns undefined

I made a template and there is a <select dojotype="dijit.form.ComboBox" dojoAttachPoint="selectPageNumber" id="selectPageNumber">tag with id and dojoAttachPoint be "selectPageNumber". I want to populate it with options upon create so I add some code to the postCreate function:
var select = dijit.byId("selectPageNumber");
or
var select = this.selectPageNumber;
but I always have select being undefined.
What am I doing wrong?
UPD:
The problem with element has been solved spontaneously and I didn't got the solution. I used neither dojo.addOnLoad nor widgetsInTemplate : true, it just started to work. But I have found the same problem again: when I added another tag I can't get it!
HTML:
<select class="ctrl2" dojotype="dijit.form.ComboBox" dojoAttachPoint="selectPageNumber" id="selectPageNumber">
</select>
<select class="ctrl2" dojotype="dijit.form.ComboBox" dojoAttachPoint="selectPageNumber2" id="selectPageNumber2">
</select>
widget:
alert(this.selectPageNumber);
alert(this.selectPageNumber2);
first alert shows that this.selectPageNumber is a valid object and the this.selectPageNumber2 is null.
widgetsInTemplate is set to false.
all the code is within dojo.addOnLoad()
dojo.require() is valid
I am using IBM Rational Application Developer (if it is essential).
WHY it is so different?
Based on your syntax, I am assuming that you are using 1.6. Your question mentions template and postCreate, so i am assuming that you have created a widget that acts as a composite (widgets in the template).
Assuming 1.6, in your widget, have you set the widgetsInTemplate property to true. This will tell the parser that your template has widgets that need to be parsed when creating the widget.
http://dojotoolkit.org/documentation/tutorials/1.6/templated/
I would remove the id from the select. Having the id means that you can only instantiate your widget once per page. You should use this.selectPageNumber within your widget to access the select widget.
If you are using 1.7 or greater, instead of setting the widgets widgetsInTemplate property, you should use the dijit._WidgetsInTemplateMixin mixin.
http://dojotoolkit.org/reference-guide/1.8/dijit/_WidgetsInTemplateMixin.html
Depending on when dijit.byId() is being called, the widget may not have been created yet. Try using dojo.addOnLoad()
dojo.addOnLoad(function() {
var select = dijit.byId("selectPageNumber");
});
I came close to the solution: it seems like there is a some sort of RAD "caching" that doesn't respond to changes made in html code.
Ways to purge the workspace environment with RAD (based on Eclipse) might be a solution.
