<select onchange="select_serviceid();" id="exist_service" name="exist_service" class="validate[required] form-control">

function select_serviceid(){
var select1 = $( "#exist_service option:selected" ).val();
var url = document.URL+'?service='+select1;
$(location).attr('href', url);
}
</script>
这里我将服务ID重定向到URL并重新加载它,但我想先检查当前URL中是否有参数。如果不是那么我添加参数,否则仅更改id值。
这是网址
http://192.168.0.24/corporate_rooms/CRS/property/service_basicinfo?service=3
参数服务希望在加载时更改

您可以使用函数替换url中的参数
function updateQueryStringParameter(uri, key, value) {
uri=uri.replace("#","");
var re = new RegExp("([?|&])" + key + "=.*?(&|$)", "i");
separator = uri.indexOf('?') !== -1 ? "&" : "?";
if (uri.match(re)) {
return uri.replace(re, '$1' + key + "=" + value + '$2');
}
else {
return uri + separator + key + "=" + value;
}
}
使用示例
var pathname = window.location.toString();
pathname=updateQueryStringParameter(pathname,"datasource",b);
window.location = updateQueryStringParameter(pathname,"setdata",a);
或者检查参数是否为:
function getUrlVars() {
var vars = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m, key, value) {
vars[key] = value;
});
return vars;
}
//example usage
var first = getUrlVars()["setdata"];
if (first != null&&typeof(first)!= 'undefined') {
//do something
}
