How to know the Id of item I clicked? my code is given below:
$(function() {
ipl.mvc.view.openings_view = ipl.mvc.view.view_base.extend({
template: '/assets/t/plmt/companies.tmpl.html',
ID: '#tmpl_openings',
events: {
"click #edit": "editpost"
},
initialize: function() {
var _this = this;
_.bindAll(this, 'addOne', 'addAll', 'render', 'editpost');
_this.loadTemplate(_this.template, function() {
_this.model = new ipl.mvc.model.companies_model([]);
_this.model.view = _this;
_this.model.bind('change', _this.render, _this);
});
}
,
render: function() {
var _this = this
jsonData = _this.model.toJSON();
_.each(jsonData, function(model) {
$(_this.ID).tmpl(model).appendTo(_this.el);
return _this;
});
}
,
editpost: function(e) {
console.log("EDIT CLICKED");
e.preventDefault();
var ele = $(e.target);
console.log(ele);
_this.model = new ipl.mvc.collection.companies_collection([]);
var id = _this.model.get("id");
alert(id);
}
});
});
and template
<a href="!/editpost/${id}" data-id="${id}"><button id="edit" ><img src="/assets/img/pencil.png" /></button></a>
I need id to use in edit function, but not getting ${id}
from template, and I follow those steps and I didn't get it? how to get the ${id}
of clicked item from template?
actually what you need is this:
you have set the data-id on the html element in the template
you added a method to be executed on the right event (editPost)
in that editPost method you can do this:
editPost: function(e){
e.preventDefault();
var id = $(e.currentTarget).data("id");
var item = this.collection.get(id);
}
remark i noticed your code has too many closing tags, so it won't run here,
and i also noticed in your editPost you try _this but you never declare _this.
you should have had var _this = this;
in that method.
remark 2 i don't understand why you even need a data-id in this example, there are two ways of rendering a view, either the view has a collection bound to it, or it has a model. When binding a collection to a view, you might somehow need to get the correct id from the element clicked to find the right model in your collection
but on your example, your view has a model bound to it, so you only have that 1 ID, which you can just get by calling this.model.get('id');
i believe your entire code example from above, is copied from another example where they use a collection in the view, since both your rendering, and the use of the data-id property suggests this.
