I am trying to declare and assign a default value to multiple variables. But the value is only getting assigned to last variable
<% var scale_text,scale_image = 'free_transform'; %>
This print empty:
<%- scale_text %>
This prints free_transform
<%- scale_image %>
What am i missing?
Separate the variables with = to set them to the same default value.
<% var scale_text, scale_image; %>
<% scale_text = scale_image = 'free_transform'; %>
What your writing will declare scale_text as an empty variable.
To work the way you want it to you need to do the following
<% var scale_text = scale_image = 'free_transform'; %>
However this is probably preferable
<% var scale_text, scale_image; %>
<% scale_text = scale_image = 'free_transform'; %>

Here is the code in nodejs(express):
response.redirect('file',{test: [{name:'sarah',arr:[1,2,3]},{name:'beck',arr: [2,3,4]}]
Now I want to access the 'arr' for every name in the array of objects.In ejs file:
<% test.forEach(index,item){ %>
<p><%= item.arr %></p>
<% }) %>
This is printed as 1,2,3 and 2,3,4 but I want the answer to be [1,2,3] and [2,3,4].Can someone help?
You can use a for .. of loop to iterate over all entries of test and then use JSON.stringify on the entries' arr property:
<% for(const testData of test){ %>
<%= JSON.stringify(testData.arr) %>
<% } %>
I pass two variables during rendering in nodejs. Let's say they're templates & treeInfo.
In template.ejs I have.
<% for(var i=0; i<templates.length; i++) {%>
<%= templates[i]._id %> = <%= treeInfo.owner[0] %><br>
<% if (templates[i]._id == treeInfo.owner) { %>
ok
<% } %>
<% } %>
So actually if == doesn't work as expected. Here's the output.
59519779f36d284c166f9bea = 5941789e36593262bed9256b
5941789e36593262bed9256b = 5941789e36593262bed9256b
So it doesn't compare them the right way. If I just replace treeInfo.owner with something like '5941789e36593262bed9256b', it does work fine.
I assume ejs doesn't support variables comparation?
Thanks
Variable type can't understand.That's why toString() is required.
<% for(var i=0; i<templates.length; i++) {%>
<%= templates[i]._id %> = <%= treeInfo.owner[0] %><br>
<% if (templates[i]._id.toString() == treeInfo.owner.toString()) { %>
__append('Hello World');
<% } %>
To compare two objects / variables in EJS, as well as in nodejs
if(user1.equals(user2))
{
console.log("Both are equal");
}
I want to create an alternating layout using the static site generator hexo – the text of every second post on an overview page should be on the right.
The partial I’m using needs to pass on a custom variable like textOrientation = "left" to the partial function.
<%site.tags.findOne({name: 'featured'}).posts.sort('date', -1).limit(5).each(function(post, index) {%>
<%- partial('_partial/project-excerpt', {item: post}) %>
<% })%>
The template project_excerp.ejs then needs to generate the according classes bases on the passed variable.
My template (project_excerp.ejs):
<a class="???" href="/project/<%= item.slug %>"><%= item.title %></a>
So the questions are:
How can I extend the post variable with my own variable textOrientation and
How can I use an if then else in my project_excerp.ejs-template?
Okay, found a solution myself.
index.js:
<%site.tags.findOne({name: 'featured'}).posts.sort('date', -1).limit(5).each(function(post, index) {%>
<% if(index % 2 === 0) { %>
<% post.textOrientation = "left"; %>
<% } else { %>
<% post.textOrientation = "right"; %>
<% } %>
<%- partial('_partial/project-excerpt', {item: post}) %>
project_excerp.ejs:
<% var projectInfoClass = "ta-right"; %>
<% if(item.textOrientation === "right") {%>
<% projectInfoClass = "ta-left"; %>
<% } %>
<a class="<%= projectInfoClass %>" href="/project/<%= item.slug %>"><%= item.title %></a>
Also helpful to read the EJS-docs.
I'm using <% include components/aside.ejs %> or <% include components/head.ejs %> somewhere in my code without any problem. But when I use include in a for loop like this
<%
for (var i = 0; i < 20; i++) {
include components/head.ejs;
}
%>
, I get Unexpected identifier in [file path] while compiling ejs.
Is there any obvious mistake that I'm not noticing?
To fix a breaking change, as of EJS 3.x, the syntax for an include has gone from <%- include components/head.ejs %> to <%- include('components/head.ejs'); %>.
You can try this one.
<% for (var i = 0; i < 20; i++){ %>
<%- include('component/footer') %>
<% }; %>
Include the template tags <% and %> on every line, like this:
<% for (var i = 0; i < 20; i++){ %>
<%- include components/head.ejs %>
<% }; %>
I am trying to figure out a way to get access to all the app.locals in the views. In my app.js I have
app.locals.title = "Title"
app.locals.page = "Page 1"
This is good, and in the views, I can access each with
<%= title %>
<%= page %>
However, is there a way (without doing something like app.locals.xyz.title) to get all the locals in the view so I can do something like this:
<% for(var i=0; i < locals.length; i ++ ){ %>
<li><%= locals[i] %></li>
<% } %>
You have to explitly pass it:
res.locals.locals = res.locals;
Then in the view:
<%= locals %>
