Please help. I have this code. I have a feeling that v-for caches (or wrongly work with it) my data array. Newly added objects (with "Add" button) are edited like the same. Try to add some rows and put some text or change a checkbox and you will see.
// Update this fn to:
addMessenger() {
this.data.profile.vsAppMessengers.push({...this.data.profile.messengerTemplate});
},
Issue was: the object is copied by reference. To read more: https://codeburst.io/explaining-value-vs-reference-in-javascript-647a975e12a0

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.
I have problem in rendering a template
When a new data has been added, it won't go to the process of v-if even if the condition is both TRUE.
Can some please explain why?
I have provided some screenshot below to explain further my issue
This first image was my template for displaying the products, you will notice the add, update and remove in here.
The second image shows that I'm trying to add a new product
The third image shows that I have successfully added the new product. The problem is, the action button "update" is triggered but won't take any effect.
The image above shows that the update button works with the past data, but not with the new one.
This last image will prove that the button has been triggered. I've added a console.log to display the following upon clicking the update button.
INDEX of the row, which is [0].
The typeOf the variable 'isUpdate' [boolean].
The value of 'isUpdate' [True, False]
and the productID which is [151]
Any idea why it hasn't been triggered, or any idea how to debugged this?
If you want to see the code. I can provide it, just tell me which part are you looking for. As I don't have any idea which part has the error.
Thank you in advance.
Updated
AS per Amresh Venugopal Request
Here is the v-if in the template
<tr v-if='product.id > 0 && product.isUpdate' class='table-inputs'>
And the updatebtn function
canUpdate: function(data) {
console.log(data.pindex);
this.products[data.pindex].isUpdate = !this.products[data.pindex].isUpdate;
console.log(typeof this.products[data.pindex].isUpdate);
console.log(this.products[data.pindex].isUpdate);
console.log(this.products[data.pindex].id);
}
I only set the isUpdate value to 'true' if 'false', and viceversa.
The productID is added after the ajax save function.
I figure it out!
When I push the data in this.products, I didn't include the 'isUpdate' field.
Got it working now.
I have a Vue instance whose data contains an array of objects. I display this data in a table without issue.
Upon clicking the table rows, I set a "selected" property on the corresponding data object using:
key.$set('testing', testing);
Upon setting this value, I add a custom css class the the table row, without issue.
However, if I do a simple output of the entire array of objects at the bottom of the page (such as below), it doesn't get updated to reflect the new "testing" attribute I have added.
{{ gridData | json }}
I was able to reproduce my question using some modified vue.js example code in this JSFiddle:
https://jsfiddle.net/wdmatl/531axrtt/
Notice when you click on rows of data, you either see "testing" or "not testing". But this new object data isn't reflected in the json at the bottom of the page. Why not?
I'm using Dojo 1.5 (including dojox). I have a dojox.grid.DataGrid where each row represents a user. When I click a row, I want to redirect to a URL like /users/USER_ID. The user ID is one of the fields in the grid, so all I need to do in my onRowClick callback is to grab the user ID for the row that was clicked.
The click event contains a rowIndex property, and, indeed, I found a (rather old) post elsewhere that suggested I should be able to do:
var row = dijit.byId('grid').model.getRow(e.rowIndex);
/* (Then grab the 0th field of the row, which is the user ID.) */
(Sorry, I've since lost the URL.)
But my grid object has no model attribute. What's up with that? Has the API changed? (My grid certainly is populated with data, which I can see, click, sort by column, et cetera).
So I'm stuck for now. Note, BTW, that it won't work to use rowIndex to directly access the grid's underlying dojo.data.ItemFileReadStore. That's because the grid is sortable, so there's no guarantee that the grid's rows will be in the same order as the store's.
Any hints would be deeply appreciated. I hope that the question is clear, and sufficiently general that any answers can help others in my predicament. Many thanks.
I have a similar scenario and I grab the value like this:
onRowClick: function(e) {
open_link(my_grid._getItemAttr(e.rowIndex, 'object_path'));
}
In this case my_grid is a reference to the datagrid and object_path is the column where I store the path to the object. open_link is of course a custom function of mine that as it implies, requests a server path.
So just change the specifics to suite your case and you should be fine.
I want to add a new node to a dijit.ree as a sibling of the currently selected node. I've found sample code (I'm new to dojo) that adds a new item to the tree using the newItem method of ItemFileWriteStore, but the new item always appears at the bottom of the tree. How would I add to the store at a specified position, in particular the position corresponding to the current selection? Pointers to sample code would be welcome :)
Thanks,
Larry
You need to find the parent item of current selected node and use that item as the parent of the newly created item.
store.newItem(itemObj, {parent : parentItem, attribute : children});
Normally an item in the store doesn't have a back pointer points to its parent. So you may need to maintain that yourself. For example, you can store the parent item's id in the child item and use fetchItemByIdentity to get the parent item.
I figured it out; here's the answer for future searchers. Use newItem as Alex suggested. Then use model.pasteItem to reposition the new item. pasteItem takes a parent (selectedNode.item.parent[0]) and a position (selectedNode.getIndexInParent()+1)
Larry
store.newItem is giving an error (Uncaught Error: dojo.data.ItemFileReadStore: Invalid attribute argument. ). Could not really find a fix for this so far and my store does not have duplicate id's.
Hence i tried using model.newItem(newItem, parentItem).
This works perfectly alright.
Thanks,
Srilatha.
