推荐答案
你必须指导用户之前附加价值,通过JavaScript的URL。使用jQuery(因为一般都自带ASP.NET封装),它可能看起来像这样(为空值或查询字符串参数手册条件检查好位):
You'd have to append the value to the URL via JavaScript before directing the user. Using jQuery (since that generally comes packaged with ASP.NET), it might look something like this (with a good bit of manual conditional checks for blank values or query string parameters):
$('#searchTechnology').click(function (e) {
e.preventDefault();
var url = '@Url.Action("SearchTechnology", "Technology", new { projectId=ProjectId })';
var technologyName = $('#technologyName').val();
if (technologyName.length < 1) {
// no value was entered, don't modify the url
window.location.href = url;
} else {
// a value was entered, add it to the url
if (url.indexOf('?') >= 0) {
// this is not the first query string parameter
window.location.href = url + '&technologyName=' + technologyName;
} else {
// this is the first query string parameter
window.location.href = url + '?technologyName=' + technologyName;
}
}
return false;
});
的想法是,当用户点击该链接,你会获取在输入
输入的值,并将其添加到URL作为查询字符串参数。然后将用户重定向到新的修改后的URL。
The idea is that when the user clicks that link, you would fetch the value entered in the input
and append it to the URL as a query string parameter. Then redirect the user to the new modified URL.
