jQuery清空表單的數(shù)據(jù)

    jQuery清空表單的數(shù)據(jù)，具體代碼如下：
    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;
    });
    };
