Ich bin neu bei Backbone js, aber genieße den Rahmen. Ich mache ein Projekt, wo es einige Listenelemente gibt und in diesen Listenelementen gibt es ein div, das die HTML-Vorlage mit einigen Attributen eines Modells haben wird. Meine Html ist:'diesen' Kontext in Backbone zuweisen js view
var FeaturedThumbnailModel = Backbone.Model.extend({
defaults:{
thumbImg_attr : 'data-dtsTooltip',
data_product_url_container :'.product-caption',
data_title :'.product-featured-title',
data_preview :'previewUrl',
data_description_container : '.product-description-container',
data_price : '.product-price-container'
},
initialize: function(){
this.tooltipFunction();
},
tooltipFunction: function(){
var thumbnailIdentifier = $('[' + this.get('thumbImg_attr') +']'),
parentThumbIdentifier = thumbnailIdentifier.closest('.thumbnail-lists'),
product_url_cont = $(this.get('data_product_url_container')),
product_title = $(this.get('data_title')),
product_Description_container = $(this.get('data_description_container')),
product_price_container = $(this.get('data_price'));
var Featured_Img = parentThumbIdentifier.find(thumbnailIdentifier).children('img').attr('src'),
Product_url = parentThumbIdentifier.find(product_url_cont).children('a').attr('href'),
Product_Title = parentThumbIdentifier.find(product_title).children('.entry-title').text(),
Product_Description = parentThumbIdentifier.find(product_Description_container).children('p').text(),
Product_Price = parentThumbIdentifier.find(product_price_container).children('.product_price').text();
this.set({
data_img : Featured_Img,
data_product_link : Product_url,
data_title : Product_Title,
data_description : Product_Description,
data_price : Product_Price
});
console.log(this);
return this;
}
});
var FeaturedThumbnailView = Backbone.View.extend({
//model : new FeaturedThumbnailModel(),
el:".big-thumbnail-container",
template :_.template("<strong><%= data_description %></strong>"),
initialize: function(){
this.model = new FeaturedThumbnailModel();
this.render();
},
render: function(){
var eles = $(this.$el);
var temp = this.template(this.model.attributes);
_.each(eles, function(element){
$(element).append(temp);
});
//console.log(this.model.get('data_description'))
return this;
}
});
$(document).ready(function(){
var thumbFunc = new FeaturedThumbnailModel({
});
var thumbView = new FeaturedThumbnailView({
el: '.big-thumbnail-container'
});
})
Die html ist anhängt, aber was:
<ul class="product-grid">
<li class="product-lists thumbnail-lists">
<div class="inline-block product-item-img-container">
<div class="product-featured-image">
<a href="" data-dtsTooltip data-title="eCommerce Theme" data-price="260"><img src="assets/img/products/pt-1.png" ></a>
<div class="product-caption">

</div>
<div class="product-featured-title">
<h1 class="entry-title">Go Fast-Transport & Logistics PSD Template</h1>
</div>
</div> <!-- product-item-img-container -->
<div class="inline-block product-description-container">

I .product-description
Inhalt im .big-thumbnail-container
für jede .thumbnail-lists
Listen
I codiert haben in js Datei angehängt werden soll passiert, dass, da es zwei Listenelemente im HTML gibt und die .big-thumbnail-container
in den beiden Listen sind, der Inhalt derselbe Inhalt ist, wird in beiden Listen als Ergebnisangehängtwiederholen sich anstelle von data_description
in jeweils .big-thumbnail-container
. Ich bin mir sicher, dass der 'this'
Kontext ich nicht zuordnen kann.

Kann mir jemand helfen? Vielen Dank im Voraus
Danke @TJ für Ihre Hilfe. Ich habe den Code geändert. Bin ich richtig in meiner Route? Ihr Kommentar
var FeaturedThumbnailModel = Backbone.Model.extend({
defaults:{
thumb_lists : '.thumbnail-lists',
descriptionClass :'.product-description-container',
}
});
var FeaturedThumbnailView = Backbone.View.extend({
initialize: function(){
this.model = new FeaturedThumbnailModel();
},
events : {
'click' :'onDescription'
},
onDescription: function(e){
e.preventDefault();
var Element = this.$el;
var templT = $(this.model.get('descriptionClass'));
console.log(Element);
var html = Element.parent().find(templT).html();
console.log(html)
var descriptionTemplate = _.template(html);
alert(html);
return this;
}
});
var FeaturedThumList = Backbone.View.extend({
render:function(thumbnailContainer){
var targets = $('.thumbnail-lists > .big-thumbnail-container');
_.each(targets, function(thumbnailContainer){
new FeaturedThumbnailView({ el: thumbnailContainer});
}, this);
}
});
$(document).ready(function(){
var featuredThumblist = new FeaturedThumList();
featuredThumblist.render('.thumbnail-lists');
});
danke @TJ für Ihre Hilfe. es ist jetzt fertig und ich habe den code geändert .. Bin ich richtig im weg? –
