I want to loop through a JavaScript object and repeat an html script as many times as the object length.
Here, I have the following in a script tag
<script>
var obj;
ipcRenderer.on('requests-results', (event, hosSchema) => {
obj = hosSchema
})
</script>
obj is an array retrieved from Mongo database as the picture below shows:
and I have the following inside <body> tag:
<div class="row">
<div class="col-md-4 col-sm-4">
<div class="card">
<div class="card-content">
<span class="card-title">.1.</span>
<p>.2.</p>
</div>
<div class="card-action">
<a href="#">.3.</a>
<a href="#">.4.</a>
</div>
</div>
</div>
</div>
How can I loop through obj to repeat the code between <div> tag as many times as obj.length?

I would suggest you to use Handlebars as @Amit mentioned.
first move out the code inside <div id="page-inner"> as below:
<div id="page-inner">
</div>
<script id= "requests-template" type="text/x-handlebars-template">
<div class="row">
{{#each requests}}
<div class="col-md-4 col-sm-4">
<div class="card">
<div class="card-content">
<span class="card-title">{{this.fieldName}}</span>
<p>{{this.fieldName}}</p>
</div>
<div class="card-action">
<a href="#">{{this.fieldName}}</a>
<a href="#">{{this.fieldName}}</a>
</div>
</div>
</div>
{{/each}}
</div>
</script>
Then inside another script page of type text/javascript you create the requests and assigned obj/hosSchema to it as below:
<script type="text/javascript">
var requestInfo = document.getElementById('requests-template').innerHTML;
var template = Handlebars.compile(requestInfo);
var requestData = template({
requests: obj
})
$('#page-inner').html(requestData);
</script>
NOTE: you need handlebars package installed (npm install handlebars --save)
