javascript - Handlebars loop to assign value to attribute -
i have values of array length dynamic. have image holder of 4. means if length of array 2, have 2 filled holder , left 2 empty holder. unfilled holder div
i've tried below code doesn't suite needs, because produce div
according length of arrays.
{{#each product.image}} <div style="background-image:url(http://example.com/{{this}})"></div> {{/each}} <div></div> <div></div> <div></div>
if want max number of 4 divs, filled data there , left empty if no data can use custom helper function:
handlebars.registerhelper('times', function (index, options) { var result = ''; for(var = 0; < 4; i++) { if(options.data.root.product.image[i]){ result += '<div style="background-image:url(https://upload.wikimedia.org'+options.data.root.product.image[i]+')"></div>'; } else { result += '<div>empty div</div>'; } } return result; });
and in html:
{{#times this}} {{/times}}
