I want to display a variable with alert I wrote the following code but instead of displaying the variable it shows me object
{{name}} is normal display
<script language="javascript">
var nom = $('name').text();
alert("Hello there this food" + nom + ". is experd.");
</script>
instead of nom he shows me object```name is part of a Template’s data ?
Your jQuery selector seems wrong, unless you created custom elements, such an element (<name />) is not supposed to exist. Instead, just select the element that contains {{ name }}.
yes name is part of a Template’s data
i try alert(“Hello there this food” + {{ name }} + “. is experd.”);
it dosnt work
This is normal, you can’t use Blaze tags in JS code. Only in HTML templates.
From where do you want to grab the name ? (onCreated, a helper, an event, …)
I’m not quite sure what you’re mean
name is a variable enter by the user
Let’s say you display the name property in a Template this way :
<template name="xxx">
...
<div class="item-name">{{ name }}</div>
...
</template>
With some JS, you can grab this value like this (as a general example) :
var name = document.querySelector( '.item-name' ).innerHTML;
alert( name );
my template
<template name="xxx">
<article class="recipe {{#if inMenu}}in-menu{{/if}}">
<h3>{{name}}</h3>
</template>
i shoud write this ?
var name = document.querySelector( '.recipe {{#if inMenu}}in-menu{{/if}}' ).innerHTML;
You can’t use Blaze tags {{ ... }} in JS code, only in HTML templates.
You are trying to put a HTML condition in a JS selector, remove it, and add the h3.
If you want to automatically alert() the name once the Template “xxx” is rendered, you should try this :
Template.xxx.onRendered(function () {
var name = this.find( '.recipe h3' ).innerHTML;
alert( name );
});
thanks for the help
but i want this
<script language="javascript">
var isAfter = moment(date).isAfter(now);
if(!isAfter)
alert("Hello there this food" + name + ". is experd.");
</script>
```so i cant do this in js code?Where did you put this <script> ?
i put the script in html page
where i display the name {{ name }}
i tried this instead the script
Template.Recipe.onRendered(function () {
var date = $('dateexp').val();
var now = moment();
var isAfter = moment(date).isAfter(now);
var name this.find( '.recipe h3' ).innerHTML;
(if isAfter){
alert( name );
}
});
```Unexpected tokenYou tried this, and ?
Your if condition is incorrect.
i correct my if condition and it still show me msg Unexpected token
Your variables declarations are still incorrect.
I can’t, just can’t… this whole topic.
