Ways to extract code within delimiters

Question

Ways to extract code within delimiters

After loading a template from a file, the structure is as follows:

[[style]].someclass{padding:10px 15px}[[/style]]
[[code]]<tr><td class="someclass">{{text}}</td></tr>[[/code]]

The template is loaded using .get() and stored in the "template" variable:

$.get('template.html', function(template) {
 if (template) {
   //extract css styles from [[style]]..[[/style]] etc.
 }
});

How can I extract the content between these markers?

I simply need to assign the contents within the blocks ([[style]]..[[/style]], [[code]]..[/code]]) to relevant variables like var style = ..., var code = ... :)

P.S. I hope my explanation makes sense... Apologies for any language issues :)

Answer №1

[[code]] and [[style]] are not recognized as standard markup language tags. Because they are not treated as DOM elements, you cannot simply use basic jQuery methods to navigate through them.

One way to handle this is by using Regular Expressions, where you can extract the contents of each code and style block and store them in separate arrays:

$.get('template.html', function (template) {
    var codeReg = /\[\[code]]([\s\S]*?)\[\[\/code]]/g,
        styleReg = /\[\[style]]([\s\S]*?)\[\[\/style]]/g,
        codes = [],
        styles = [],
        item;
    while (item = codeReg.exec(template))
        codes.push(item[1]);
    while (item = styleReg.exec(template))
        styles.push(item[1]);
    console.log(codes);
    console.log(styles);
});

Modify the content inside a code tag:

$("code").html("*insert your desired text here*");

Adjust the styling of an element using CSS properties. You can target elements by id (using '#'), class (using '.'), or type (like "body", "code", "div"). It's recommended to use CSS instead of changing the HTML directly:

$("*element*").css({*property*: *value*, *property*: *value*});
$(".*class*").css({*property*: *value*, *property*: *value*});
$("#*id*").css({*property*: *value*, *property*: *value*});

*You are free to customize anything enclosed in asterisks*
