What are the commonly used jquery methods?
jquery effect
1.隐藏/显示 hide（），show（），toggle（） 2.淡入/淡出 fadeIn（），fadeOut（），fadeToggle（），fadeTo（）Copy after login
fadeTo（speed，opcity）这个不常用，但是效果好。opcity取0~1之间的值
3.滑动 slideUp（），slideDown（），slideToggle（） 4.动画 animate（） $().animate(参数,speed,callback);Copy after login
注：动画的属性名称必须使用marginLeft这种而不是margin-left 可以设置相对值。如："left":"+=10px" animate()可以设置队列动画，即动画的不同属性按顺序写，他就会按顺序执行
5.stop（stopAll,goToEnd）Copy after login
该方法在动画执行完之前就可以结束动画。适用于所有 jQuery 效果函数,包括滑动、淡入淡出和自定义动画。
stopAll 参数规定是否应该清除动画队列。默认是 false，即仅停止活动的动画
goToEnd 参数规定是否立即完成当前动画。默认是 false。6.jquery chain
$("#p1").css("color","red")
.slideUp(2000)
.slideDown(2000);
jQuery 会抛掉多余的空格，并当成一行长代码来执行上面的代码行。Note: The above methods all have callback functions. If the callback is an anonymous function, it can be executed immediately. The function name is toggle and the execution is completed.
jquery HTML
Return content
1.html(),text(),val()(这三种方法同样存在回调函数)Copy after login
html或者text或者val（function（i，origvalue）{}）
回调函数有两个参数：被选元素列表中当前元素的下标，以及原始（旧的）值。
区别：html（）可以返回标签结构，其他两个只返回文本2.attr()和prop的区别 (这种方法同样存在回调函数)Copy after login
我觉得attr用与获取和设置自定义的属性。prop用于获取标签固有的属性
attr（function（i，origvalue）{}）3.添加文本append（），prepend（）。before（），after（）Copy after login
前两个是在所选元素里面的前后添加 后两个是在所选元素的外部的前后添加
4.删除元素/内容 remove（），empty（）Copy after login
前者删除被选元素及其子元素 后者删除被选元素的子元素
5.操作css addClass（”class1,class2,,,”）,removeClass(),css() 注：css方法和animate（）方法不同，css方法属性使用的是margin-left而不是marginLeft 6.元素尺寸Copy after login
width（），height（），innerWidth（），innerHeight（），outerWidth（），outHeight（） width()，height（）==元素的宽高（不包括padding， margin，和border） innerWidth（），innerHeight（）==元素的宽高+padding（不包括margin和border） outerWidth（），outHeight（）==元素的宽高+padding+border（不包括margin）
jquery traversal
jquery traversal
1.父 parent（），parents（）； 2.子 children（），find（） 3.同胞 siblings（）,pre（）,next（） 4.过滤 first（），last（），eq（），filter（），not（） $(“p”).filter(“.url”);返回带有类名 “url” 的所有 元素： $(“p”).not(“.url”);返回不带有类名 “url” 的所有 元素： **
jquery Ajax
**
Syntax: $.ajax({name:value, name:value, … })
Ajax asynchronous request five Steps
Step one:
var xmlhttp;if (window.XMLHttpRequest)
{ // IE7+, Firefox, Chrome, Opera, Safari 浏览器执行代码
xmlhttp=new XMLHttpRequest();
}else{ // IE6, IE5 浏览器执行代码
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}Step two: Set parameters
url：”“， type:”“， success: ，error：等Copy after login
Step three and four:
xmlhttp.open(“GET”,”url”,true); 例如：”a.php?t=” +Math.random()” xmlhttp.send();Copy after login
Step 5:
xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById(“myp”).innerHTML=xmlhttp.responseText; } }Copy after login
get is different from post: get is submitted to the address bar. Post is submitted to the background php page. So if it is a get method, please write the url like this: For example: "a.php?name=zhangsan&age=14"
Finally, we will process the data returned by the server
xmlhttp.responseText; 获得字符串形式的响应数据。 xmlhttp.responseXML; 获得 XML形式的响应数据。Copy after login
ajax handles php/xml/jsp and other files the same way. Mainly depends on what the returned data looks like, and then handles it accordingly
Because many js frameworks use $ as the abbreviation symbol. If you use multiple frameworks, jquery will stop running.
Solution: jQuery noConflict() method
1. Create your own representation symbol instead of $
var jq = $.noConflict();
jq(document).ready(function(){
jq("button").click(function(){
jq("p").text("jQuery 仍然在工作!");
});
});2. Use jQuery to express it outside, and use $
$.noConflict();
jQuery(document).ready(function($){
$("button").click(function(){
$("p").text("jQuery 仍然在工作!");
});
});jquery JSONP
The src attribute of the script tag does not have the restriction feature of the domain name;
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JSONP 实例</title>
<script src="http://cdn.static.runoob.com/libs/jquery/1.8.3/jquery.js"></script> </head><body><p id="box"></p><script>$.getJSON("http://www.runoob.com/try/ajax/jsonp.php?jsoncallback=?", function(data) {
//data就是服务器返回给我们的数据，我们只需要对他进行处理即可
var html = '<ul>';
for(var i = 0; i < data.length; i++)
{
html += '<li>' + data[i] + '</li>';
}
html += '</ul>';
$('#box').html(html);
});
</script>
</body>
