In normal JavaScript, a developer will not receive any error feedbackĪssigning values to non-writable properties. set attribute of all models in backbone collection Ask Question Asked 10 years, 5 months ago Modified 6 years ago Viewed 20k times 18 I understand that using pluck method we can get an array of attributes of each model inside a backbone collection var idsInCollection uck ('id') // outputs 'id1','id2'. To accidentally create a global variable. In strict mode, this will throw an error, making it impossible Strict mode changes previously accepted "bad syntax" into real errors.Īs an example, in normal JavaScript, mistyping a variable name creates a new ![]() Strict mode makes it easier to write "secure" JavaScript. So "use strict" only matters to new compilers that "understand" the meaning The syntax, for declaring strict mode, was designed to be compatible withĬompiling a numeric literal (4 + 5 ) or a string literal ("John Doe" ) in a JS References JavaScript Objects HTML DOM Objects Generally, events are not declared before they are even bound they are simply passed arguments.

This is an advanced post on backbone Models, be sure to check out my main post on them before reading this if you are new to backbone. In this post I will be showing some simple examples of the set model method in backbone. However it is important to use the set method to set values rather than directly modifying the attributes object so that any events that have been defined will work. ![]() Getting values is not a big deal as the model.get(‘foo’) method is just a shorthand for. ![]() When making a backbone Model, I am going to get into many situations in which I will want to get, and set values for various attributes in the attributes object of a backbone Model.
