javascript - Using a variable as a classname -


i trying put class name stored in variable jquery want class be, should change class affected depending on parameter passed through url query string. have built class name , stored in 'param' variable below. 

var param = '".' + "proj" + location.search.substring(6) + '"';       $(param).css('display', 'inline');

and want change css on class inside of not seem work me. perhaps because tries change css of variable rather inside of it. if not how can solve or if so, there better way go this?

you're confusing string literal enclosed double quotes ", while not case. remove them

var param = '.' + "proj" + location.search.substring(6);

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
