jquery - 如何使用 :input in jquery? 排除只读字段

Question

到目前为止，我只使用了一些基本的 jquery 选择器和函数。但我正在看这个clear form function我不知道如何添加它，以便我可以删除隐藏输入和只读输入以防止清除。

有人可以帮忙吗？谢谢。

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;
  });
};

如果元素的声明中有 readonly 属性，则可以使用 jQuery’s :not() selector :

$(':input:not([readonly])', form)

否则，使用如下内容过滤只读元素:

$(':input', form).each(function() {
    if (this.readOnly) return;
    // …
});
