Convalida Jquery per convalidare l'URL

Question

Sto tentando di convalidare l'URL in jQuery regular expression utilizzando il codice riportato di seguito. Si sta lavorando bene con http://www e https://www

var myVariable = "http://www.example.com/2013/05/test-page-url-512-518.html"; 

if(/^(http:\/\/www\.|https:\/\/www\.|http:\/\/|https:\/\/|www\.)[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?$/.test(myVariable)){ 
    alert("valid url"); 
} else { 
    alert("invalid url"); 
} 

Edit: -

Sopra lavoro codice perfettamente per convalidare URL. Quella volta la mia esigenza era solo per convalidare http://www e https://www

Answer 1

vostro modello è definito come

^(http:\/\/|someting else

quindi any-urls inizia con "http: //" sarebbe validat ed.

Answer 2

provare questo --->

var myVariable = "http://www.Test.com/"; 
if(/^([a-z]([a-z]|\d|\+|-|\.)*):(\/\/(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:)*@)?((\[(|(v[\da-f]{1,}\.(([a-z]|\d|-|\.|_|~)|[!\$&'\(\)\*\+,;=]|:)+))\])|((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=])*)(:\d*)?)(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*|(\/((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)?)|((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)|((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)){0})(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|\/|\?)*)?$/i.test(myVariable)) { 
    alert("valid url"); 
} else { 
    alert("invalid url"); 
} 

Answer 3

Scegli questa - http://docs.jquery.com/Plugins/Validation/Methods/url

$("#myform").validate({ 
    rules: { 
    field: { 
     required: true, 
     url: true 
    } 
    } 
}); 

Answer 4

È possibile modificare la Regex, in realtà v'è una ripetizione di elemento cioè http:\/\/|https:\/\/|www\.

Questo codice funzionerà per voi:

var myVariable = "http://www.example.com/2013/05/test-page-url-512-518.html"; 

if(/^(http:\/\/www\.|https:\/\/www\.)[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?$/.test(myVariable)){ 
    alert("valid url"); 
} else { 
    alert("invalid url"); 
} 

Answer 5

si desidera convalidare il tuo URL:

prega passare l'URL in questa funzione quindi questo ti darà true OR false.

La funzione:

<script> 
function isUrl(s) { 
    var regexp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/ 
    return regexp.test(s); 
} 

isUrl(yourURL); 
</script>
