localStorage test

Idag testade jag localStorage på en av mina sajter och jag måste säga att det är väldigt coolt 🙂

Jag valde att spara alla inmatning i localStorage tills man valt skicka väg formuläret. namnet på formulär fältet används som nyckel i localStorage men det det bör inte vara något större problem att kombinera formulärets id eller action attribut.

ls = {
	set : function(name, value){
		if(window.localStorage){
			localStorage.removeItem(name);			
			localStorage.setItem(name, value);			
		}
	},
	get : function(name){
		if(window.localStorage){
			return localStorage.getItem(name);
		}
	},
	clear : function() {
		if(window.localStorage){
			return localStorage.clear();
		}
	}
}; 


$(document).ready(function(){
	
	$(":input").each(function(){
		if($(this).val() == "" && ls.get($(this).attr("name")) != ""){
			$(this).val(ls.get($(this).attr("name")));
		}									
	});
	
	$(":input").change(function(){
		if($(this).val() != ""){
			ls.set($(this).attr("name"), $(this).val());
		}									
	});

	$("form").submit(function(){
		form = this; 
		$(form).find(":input").each(function(){	
			ls.set($(this).attr("name"), "");
		});				
	});	
});

Jag gillar jquery


<a id="mail"></a>

(function($) {
    $.fn.extend({
        mailLink: function(options) {
        
    		var defaults = {
                userName: "nobody",
                domainName: "localhost",
                topLevelDomain: ""    		                
            };

            var options = $.extend(defaults, options);
					    		
    		return this.each(function() {
    	    	var obj = $(this);
    	    	var emailAdress = options.userName + "@" + options.domainName + ( (options.topLevelDomain == "") ? "" : "." ) + options.topLevelDomain;  
    	    	obj.attr("href","mailto:" +emailAdress).text(emailAdress);
    		});
        }
    });
})(jQuery);

$(document).ready(function(){
$("#mail").mailLink({userName:'info', domainName:'reurl', topLevelDomain:'se'});
});
