Hello,
How can I use simple if statement inside the template ? I want to check for greater than or equal to. Assuming that getdata method returns some value.
{{#if getdata > 1}}
<p>Greater than 1</p>
{{else}}
<p>Less than 1 or 1</p>
{{/if}}
This ain’t working. Any help ?
You can’t enter such statements in your templates but need just a helper for that like
template.mytemplate.helpers({
check_greater_than_1: function () { return getdata > 1 }
})
and then in template
{{#if check_greater_than_1}}
You also may check for helpers with argument like
function check_greater_than(a,b) { return a > b }
usage
{{#if check_greater_than {{getdata}} 1}}
Checkout helpers in guide.
Thank you so much sir. Actually problem is that I have this code.
{{#if getdata}}
//true
{{else}}
//false
{{/if}}
Now problem is that even if my helper method returns null data it returns true. I don't want to show anything when returned value is null.
The {{#if
condition checks the existing of the var so that is why its true
create yourself a helper
function check_getdata() { return getdata && getdata !== null }
So I have to create 2 helpers ?
Maybe, depends on your tests
Otherwise try to install undescore helper like https://github.com/gwendall/meteor-underscore-helper
Then you may use ‘_’ and its function like ‘_.undefined’ in your templates
Are you sure it is working on latest meteor 1.3.x ? Because I have tried several functionalities but not working in template.
What user id do I have: {{$.Meteor.userId}}
@tomfreudenberg : How can I call my function in next helper function ?
"first" ()
{
return "Hi";
},
"second" ()
{
return this.first();
}
This is not working.
You need to place your functions outside the helpers like
let my_funcs = {
first,
second
}
and then use in helper just
"first" ()
{
return my_func.first();
},
"second" ()
{
return my_func.first();
}
This is also a good organization approach.

but do use {{#if $gt XXX XXX}}

accountID == members[i].user_id ? currentBalanceDetails = members[i] : null;
if we use condition then also use this type of method
