创建一个HTML元素并保留一个引用
var newDiv = $("<div />");
newDiv.attr("id", "myNewDiv").appendTo("body");
/* Now whenever I want to append the new div I created,
I can just reference it from the "newDiv" variable */
检查元素是否存在
if ($("#someDiv").length)
{
// It exists...
}
编写自己的选择器
$.extend($.expr[":"], {
over100pixels: function (e)
{
return $(e).height() > 100;
}
});
$(".box:over100pixels").click(function ()
{
alert("The element you clicked is over 100 pixels height");
});
在元素创建时定义属性
在jQuery 1.4中,你可以在创建元素时使用对象文字来定义属性:
var e = $("<a />", { href: "#", class: "a-class another-class", title: "..." });
... 你甚至可以添加样式:
$("<a />", {
...
css: {
color: "#FF0000",
display: "block"
}
});

(这是一个无耻的插头)
与其写重复的表单处理代码,你可以试试我写的这个插件,它通过添加表单相关的方法添加到jQuery的流畅API:
// elementExists is also added
if ($("#someid").elementExists())
alert("found it");
// Select box related
$("#mydropdown").isDropDownList();
// Can be any of the items from a list of radio boxes - it will use the name
$("#randomradioboxitem").isRadioBox("myvalue");
$("#radioboxitem").isSelected("myvalue");
// The value of the item selected. For multiple selects it's the first value
$("#radioboxitem").selectedValue();
// Various, others include password, hidden. Buttons also
$("#mytextbox").isTextBox();
$("#mycheck").isCheckBox();
$("#multi-select").isSelected("one", "two", "three");
// Returns the 'type' property or 'select-one' 'select-multiple'
var fieldType = $("#someid").formElementType();
