I am looking to implement a solution that involves adding a div container holding 4 images based on the JSON data provided below:
var pictures = [
{img_path: "1/1.jpg"},
{img_path: "1/2.jpg"},
{img_path: "1/3.jpg"},
{img_path: "1/4.jpg"},
{img_path: "1/5.jpg"},
{img_path: "1/6.jpg"},
{img_path: "1/7.jpg"},
{img_path: "1/8.jpg"},
{img_path: "1/9.jpg"},
{img_path: "1/10.jpg"}
];
The code snippet for my handlebar template is as follows:
<script id="gallery-template" type="text/x-handlebars-template">
@{{#each pictures}}
@{{#compare @index '%' 4}}
<div class="outer">
{{/compare}}
<img src="@{{img_path}}" />
@{{#compare @index '%' 8}}
</div>
{{/compare}}
@{{/each}}
</script>
Handlebars.registerHelper('compare', function (lvalue, operator, rvalue, options) {
var operators, result;
if (arguments.length < 3) {
throw new Error("Handlerbars Helper 'compare' requires 2 parameters");
}
if (options === undefined) {
options = rvalue;
rvalue = operator;
operator = "===";
}
operators = {
'==': function (l, r) { return l == r; },
'===': function (l, r) { return l === r; },
'!=': function (l, r) { return l != r; },
'!==': function (l, r) { return l !== r; },
'<': function (l, r) { return l < r; },
'>': function (l, r) { return l > r; },
'<=': function (l, r) { return l <= r; },
'>=': function (l, r) { return l >= r; },
'typeof': function (l, r) { return typeof l == r; },
'%': function (l, r) { return l % r == 0; }
};
if (!operators[operator]) {
throw new Error("Handlerbars Helper 'compare' does not recognize the operator " + operator);
}
result = operators[operator](lvalue, rvalue);
if (result) {
return options.fn(this);
} else {
return options.inverse(this);
}
});
Although the initial div creation logic appears to be in place, I am encountering challenges with properly closing the div tags. The aim is to group the images in sets of 4, with appropriate closure - i.e., for a total count of 10 images, the division should be 4, 4, and 2 respectively. Feel free to suggest modifications to the JSON structure to achieve this desired outcome.
