Most PHP apps use parameters to query data. There are many cases you have to handle these parameters on front-end, hence JavaScript or jQuery is used. Actually, jQuery isn’t necessary in this case. Below are small code snippets which can help you retrieve any parameters in a URL.
Get parameters from current URL:
[javascript]
//if URL contains '?test=true'
var isTest = getCurrentURLParamValue('test');
function getCurrentURLParamValue(param){
var urlParams = window.location.search.substring(1);
var urlParamsArray = urlParams.split('&');
for (var i = 0; i < urlParamsArray.length; i++){
var urlParamName = urlParamsArray[i].split('=');
if (urlParamName[0] == param){
return urlParamName[1];
}
}
}
[/javascript]Get parameters from any given URL:
[javascript]
//if URL contains '?test=false&title=A+Test+Title'
var isTest = getURLParamValue('http://www.example.com/index.php?test=false&title=A+Test+Title', 'test');
var title = getURLParamValue('http://www.example.com/index.php?test=false&title=A+Test+Title', 'title');
function getURLParamValue(url, param){
var results = new RegExp('[\?&]' + param + '=([^&#]*)').exec(url);
if (results != null){
return decodeURIComponent(results[1]);
} else{
return null;
}
}
[/javascript]
