使用Javascript将参数从URL传递到隐藏表单域(Gridview)

function getParameterByName(name) {
  name = name.replace(/[\[\]]/g, "\\$&");
  var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
      results = regex.exec(window.location.href);
  if (!results) return null;
  if (!results[2]) return '';
  return decodeURIComponent(results[2].replace(/\+/g, " "));
}

var parameterValue = getParameterByName("parameterName");
document.getElementById("hiddenField").value = parameterValue;
