jquery清空表单数据示例分享

复制代码代码如下:
function clearForm（form） {
// iterate over all of the inputs for the form
// element that was passed in
$（":input", form）.each（function（） {
    var type = this.type;
    var tag = this.tagName.toLowerCase（）; // normalize case
    // it"s ok to reset the value attr of text inputs,
    // password inputs, and textareas
    if （type == "text" || type == "password" || tag == "textarea"）
      this.value = "";
    // checkboxes and radios need to have their checked state cleared
    // but should *not* have their "value" changed
    else if （type == "checkbox" || type == "radio"）
      this.checked = false;
    // select elements need to have their "selectedIndex" property set to -1
    // （this works for both single and multiple select elements）
    else if （tag == "select"）
      this.selectedIndex = -1;
}）;
};
