backbone.js - Iterate through arbitrary json in backbone/underscore template -


in normal case value via key, value of name <%= name %>, have know key "name". question if not know key of json field in first place, how can iterate through them, example, dump key-value pairs in table?

you transform object array of objects keys , values attributes. example,

var obj = {one: 1, two: 2, three: 3};  var fields = _.map(     _.pairs(obj),     function(pair) {         return {             key: pair[0],             value: pair[1]         };     } );

would yield [{key: "one", value: 1}, {key: "two", value: 2}, {key: "three", value: 3}]

you can feed array template, 

var template = _.template(     '<% _(list).each(function(field) { %>'+         '<%= field.key %> : <%= field.value %><br>'+     '<% }); %>' ); $('body').append(template({     list: fields }));

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
