I have the following page http://example.com (Yes, I know it's slow right now), but I need to rearrange the "dealers" under the correct states. Some of them are in the wrong location, using jquery I need to remove them and place them under the correct headers (There are no wrapping containers for each state).
I'm having a hard time doing this, how would I remove each Dealer (they have their own containers) with a data variable with the State value under the h4 with the matching state value? The data variable is data-state for each location and h4..
This will detach all of those dealerContainers, then append them back in their correct locations.
$('.dealerContainer[data-state]')
.detach()
.each(function(i,e) {
var state = $(e).data('state');
var stateh5 = $('h5[data-state='+state+']');
$(e).insertAfter(stateh5);
})

I have a div element which is populated with new innerHTML every time a forward or back button is clicked. But, when I use JS to store its information in a variable and console.log it I get unexpected data.
var unitName = document.querySelector("#unitName");
console.log(unitName, unitName.innerHTML.length);
The unitName will display as the current unitName, but the unitName.innerHTML.length will display the value of the previous unitName's HTML length.
Using setTimeOut will work around this and match up the apporopriate values, but is there another way to do this that doesn't involve using setTimeOut?
I have an edit popup, when the popup opens and i edit, it is reflecting on the table. I must avoid the reflection, once i click on save button then only the edited part must be displayed on the table. I am able to do this only for one input, i am not getting how to carry out the same way for other 2 inputs.
//Ts
editTutorial(tutorial) {
this.editTutorials.show();
this.edit_tut = tutorial;
}
You are assigning tutorial value which you sent from table into edit_tut varable, which is working as two-way binding.
so, the data in the table is getting changed along with your input.
The solution can be changing the variable reference, you can do something like,
editTutorial(tutorial) {
this.editTutorials.show();
let tut = JSON.parse(JSON.stringify(tutorial))
this.edit_tut = tut;
}
This will change the value reference and will work for you.
You have to have two different properties on your component, referencing to two different object instances. Few things to do:
Step 1: on clicking "edit", make a copy of the table row (all props) and put them inot the modal. Keep the reference to, e.g. table row you're editing, or _id or something.
In your case, add a property to TutorialComponent called currentlyEditing: any. Then, modify your editTutorial method:
editTutorial(tutorial) {
this.editTutorials.show();
this.currentlyEditting = tutorial;
}
Step 2: editing those should not reflect on the table. Go on and edit your thing.
Step 3: upon saving, sync your changes back to the table, or rather, to the original data set that's being displayed in the table. That's why you needed the reference from step 1.
Now, it's not clear to me if your edit_tut component is the one that saves changes. But if it is, I think everything will work as is. If not, you'd have to, after saving and response of "success", go and find the original tutorial in the tutorials array, and replace it with the edited component.
This may well be a very basic problem for anyone familiar with knockout.js, however it is causing me a problem.
I have a situation where I have a model containing an array of items that is dynamically added to and displayed in the view.
So far no problem, I can add entries into the model and the view is updated appropriately.
However. each item in the array itself has an array as a property, this is an array of object, and when I update the properties on these objects the view is not updated.
It is difficult to demonstrate this is a short code snippet so I have created a JsFiddle to show the problem:
https://jsfiddle.net/mikewardle/t0nvwqvL/1/
I have tries making the properties generated by calling
ko.observable()
rather than initializing them directly, but to no avail.
clicking the add button adds items to the array on the model itself.
either of the change... buttons alters the properties of the objects in the inner array.
As Ko2r stated your properties are not declared as observables and therefore updates will not be noticed by knockout.
To fix your changecolors() function you just need to change your linePusher function to create the color as an observable:
var linePusher = function (color, name) {
self.lines.push({ color: ko.observable(color), name: name, current:0 });
};
and then update usages of the color property to box/unbox the observable instead of replacing its value with the standard assignment operator, "="
for (i=0;i<counters.length;i++){
var lines = counters[i].lines();
for (j=0;j<lines.length;j++){
//lines[j].color = color;
lines[j].color(color); //sets the existing observable to the new value
}
}
Unfortunately I can't seem to make sense of your code enough to figure out what the increment() function is supposed to be doing so I can't tell you how to fix it, but hopefully the fixes to changecolors() put you on the right track.

My app uses a Parse backend to keep a running list of all the concerts in my area that my friends and I are interested in.
On the main page I use a parse query display a module for each show stored in the database. As each module is created, I use this code to add a data attribute to the show's outermost div, corresponding to the show's object ID in parse:
var showId = object.id;
$("div.show_module:last").data("showId", showId);
I'm successfully able to retrieve the showId of a specific show when the user clicks on the show's module:
$("#showsList").delegate(".showModuleBody", "click", function() {
var storeObjectId = $(this).closest("div.show_module").data("showId");
});
That all works great, proving that assigning the data-attribute is working.
Where I'm running into trouble is trying to find an element with a specific data attribute or a specific value for that attribute on a given page. The end goal is to get the y-offset of that div so I can scroll the page to the appropriate spot. I assumed I could use the following code to find the element, but it isn't working -
// find all elements with class .show_module
var allShows = document.querySelectorAll('.show_module');
// find all elements with showId data attribute
var showsWithShowId = document.querySelectorAll('[data-showId]');
// find all elements with a specific showId data attribute
var showToFind = document.querySelectorAll("[data-showId='2']");
The first of those 3 works, proving that all the elements I'm interested in are loaded into the page by the time I'm calling this function, but the 2nd and 3rd queries return nothing.
Any idea what I'm doing wrong here? Is it something with syntax? Is querySelectorAll just incompatible with how I'm setting the data attribute?
I tried to include only what I figured are the salient bits of code, but if more is necessary please let me know.
Try This
$('*[data-customerID="22"]');

Selecting element by data attribute
jQuery's .data method does not create a HTML attribute, but associates a value in its internal data store with the element.
If you want to set a data attribute with jQuery, then you need to use:
$("div.show_module:last").attr("data-showId", showId);
To get the value, you can use .data('showId') or .attr('data-showId').
(note that HTML attributes are case-insensitive, so you can also write "data-showid" instead.)
I have this controller with a value.
App.xcontroller = SC.ArrayController.create({
...some code...
array_values = [],
..more code...
})
Now i have somewhere in a view this valueBinding
valueBinding: 'App.xController.array_values',
When I change values in the array the view does not get updated. but when i do
the following in the controller:
var array_values = this.get('array_values');
... adding / removing values to the array....
if (x_values.contains(x)){
x_values.removeObject(x)
} else {
x_values.pushObject(x);
};
this.set('array_values', array_values.copy());
the binding works, the view gets updated. But ONLY with the copy().
I don't want to make a copy of the array, IMHO this is not efficient. I just want to
let the valueBinding know content has changed..
the x values are just a bunch of integers.
The reason i want this: I want to change the value key of a SegmentedItemView. I want to change the active buttons. But I do not know on forehand how many segmentedviews I have
so I thought i bind the value of every generated segemented view to some common array and change that common array to be able to change the active buttons on all of the segmented views. Since each button represents an item with an unique key it works fine. except that i have to copy the array each time.
set the content property of the xcontroller
Bind to the arrangedObjects property of the xcontroller
You need to use KVO compliant methods on the array to get the bindings to fire. The ArrayController itself has an addObject and removeObject methods. Arrays in SC have been augmented with a pushObject method (among others), which is also KVO compliant. So if you use the KVO methods the view should update.
The reason your view does not update is because you are bound to the array, but the array itself did not change. When you do a copy, the array itself changes, so the bindings fire.
You might also want to try
this.notifyPropertyChange('x_values');
in the controller after you make the changes, but that is less preferable to using the built in KVO functionality.
