JSON.stringify returns a String. So, for example: var data = [ { id: 1, name: “bob” }, { id: 2, name: “john” }, { id: 3, name: “jake” }, ]; JSON.stringify(data) will return the equivalent of: “[{\”id\”:1,\”name\”:\”bob\”},{\”id\”:2,\”name\”:\”john\”},{\”id\”:3,\”name\”:\”jake\”}]” as a String value. So when you have <% for(var i=0; i<JSON.stringify(data).length; i++) {%> what that ends up … Read more
Conditionals work if they’re structured correctly, I ran into this issue and figured it out. For conditionals, the tag before else has to be paired with the end tag of the previous if otherwise the statements will evaluate separately and produce an error. ERROR! <% if(true){ %> <h1>foo</h1> <% } %> <% else{ %> <h1>bar</h1> … Read more
The same way you would do it with anything in js, typeof foo == ‘undefined’, or since “locals” is the name of the object containing them, you can do if (locals.foo). It’s just raw js :p
Edit: this Half considers you are using EJS on server side 1) You can pass an ejs variable value to a Javascript variable <% var test = 101; %> // variable created by ejs <script> var getTest = <%= test %>; //var test is now assigned to getTest which will only work on browsers console.log(getTest); … Read more
You are escaping the value correctly by using: <%= bloglist[i].Text %> If you want to allow HTML to be rendered, then you want an “unescaped” value. To do that use the following: <%- bloglist[i].Text %> All I did was replace the equal (=) with a dash (-). Reference: https://github.com/visionmedia/ejs/tree/0.8.3#features
After having a chance to study the Express 3 API Reference a bit more I discovered what I was looking for. Specifically the entries for app.locals and then a bit farther down res.locals held the answers I needed. I discovered for myself that the function app.locals takes an object and stores all of its properties … Read more
Oh that was easy, don’t use <%=, use <%- instead. For example: <%- JSON.stringify(user) %> The first one will render in HTML, the second one will render variables (as they are, eval)
In Node.js: res.render(‘mytemplate’, {data: myobject}); In EJS: <script type=”text/javascript”> var rows =<%-JSON.stringify(data)%> </script> SECURITY NOTE : Don’t use this to render an object with user-supplied data. It would be possible for someone like Little Bobby Tables to include a substring that breaks the JSON string and starts an executable tag or somesuch. For instance, in … Read more
With Express 3.0: <%- include myview.ejs %> the path is relative from the caller who includes the file, not from the views directory set with app.set(“views”, “path/to/views”). EJS v1 includes EJS v2 includes (Update: the newest syntax for ejs v3.0.1 is <%- include(‘myview.ejs’) %>)
With EJS you can have several tags: <% code %> … which is code that is evaluated but not printed out. <%= code %> … which is code that is evaluated and printed out (escaped). <%- code %> … which is code that is evaluated and printed out (not escaped). Since you want to print … Read more
