backbone.jsHow do I create a form submit using Backbone.js?
Backbone.js provides a simple way to create a form submit. To do this, you will need to create a model, a view, and a template.
First, create a model with the attributes you want to submit in the form. For example:
var FormModel = Backbone.Model.extend({
defaults: {
name: '',
email: ''
}
});
Next, create a view that will contain the template, and handle the form submit. The view should bind to the model, and listen for the submit event. For example:
var FormView = Backbone.View.extend({
el: '#form',
model: new FormModel(),
template: _.template($('#form-template').html()),
events: {
'submit': 'handleSubmit'
},
render: function() {
this.$el.html(this.template(this.model.toJSON()));
return this;
},
handleSubmit: function(e) {
e.preventDefault();
//handle the form submit here
}
});
Finally, create a template to render the form. It should contain the form elements and the submit button. For example:
<script type="text/template" id="form-template">
<form>
<input type="text" name="name" value="<%= name %>" />
<input type="text" name="email" value="<%= email %>" />
<input type="submit" value="Submit" />
</form>
</script>
Now you can create a new instance of the view and render it:
var formView = new FormView();
formView.render();
The form submit will now be handled by the handleSubmit
function in the view.
