Ok, the scenario is that I have a list of objects that itself contains a list of objects. I am trying to put the outer objects in a list in my View-Model and I'm trying to turn the inner objects into an object I created as a model with an extra property, like so -
function Tag(data, isChecked) {
var TagId = ko.observable(data.TagId);
var Description = ko.observable(data.Description);
var IsActive = ko.observable(data.IsActive);
var checked = ko.observable(isChecked)
}
Here is how i'm doing it.
$.each(parentTags, function (i, tag) {
var tempTag = tag[i];
for (Object in tag.ChildTags)
{
var checked = false;
for(checkedItem in savedTags)
{
if(tag.ChildTags[Object].TagId === savedTags[checkedItem])
{
checked = true;
}
}
//var tempChild = new Tag(tag.ChildTags[Object], checked);
tempTag.ChildTags.push(new Tag(tag.ChildTags[Object], checked));
}
viewModel.ModelTags.push(tempTag);
});
parentTags = [[object Object],[object Object],[object Object],[object Object],[object Object],]
I'm definitely new to json and knockout. Any help would be appreciated.
This is what I have now and it seems to be working.
$.each(parentTags, function (i, tag) {
var tempTag = new Tags(JSON.parse(JSON.stringify(tag)));
tempTag.ChildTags().length = 0;
for (Object in tag.ChildTags) {
var checked = false;
for (checkedItem in savedTags) {
if (tag.ChildTags[Object].TagId === savedTags[checkedItem]) {
checked = true;
}
}
tempTag.ChildTags().push(new Tag(tag.ChildTags[Object], checked));
}
viewModel.ModelTags().push(tempTag);
});
What are you doing with var tempTag = tag[i];? The variable tag is already the i-th member of parentTags.
If I understand you correctly, try this:
function Tag(data, isChecked) {
// not "var TagId", please.
this.TagId = ko.observable(data.TagId);
this.Description = ko.observable(data.Description);
this.IsActive = ko.observable(data.IsActive);
this.checked = ko.observable(isChecked);
}
$.each(parentTags, function (i, tag) {
// map each child tag into a Tag object
var tags = $.map(tag.ChildTags, function(cTag) {
return new Tag(cTag, $.inArray(cTag.TagId, savedTags));
});
// replace with Tag objects
tag.ChildTags = tags;
// push modified tag onto vm
viewModel.ModelTags.push(tag);
});
