问题:

I have tried $("#client.frm").reset(); but it is not working.So how to reset form via jQuery?

回答1:

form.reset() is a DOM element method (not one on the jQuery object), so you need:

$("#client.frm")[0].reset();
//faster version:
$("#client")[0].reset();

Or without jQuery:

document.getElementById("client").reset();


回答2:

You can simply do:

$("#client.frm").trigger('reset')



回答3:

Pure JS solution is as follows:

function clearForm(myFormElement) {

  var elements = myFormElement.elements;

  myFormElement.reset();

  for(i=0; i<elements.length; i++) {

  field_type = elements[i].type.toLowerCase();

  switch(field_type) {

    case "text":
    case "password":
    case "textarea":
          case "hidden":

      elements[i].value = "";
      break;

    case "radio":
    case "checkbox":
        if (elements[i].checked) {
          elements[i].checked = false;
      }
      break;

    case "select-one":
    case "select-multi":
                elements[i].selectedIndex = -1;
      break;

    default:
      break;
  }
    }
}
