2002年的某晚。 关山口职业技术学院，西九楼电子系。 我在电脑上开着frontpage 2000,苦苦琢磨javascript。

2009年，我找到了jQuery,惊呼原来js可以这么方便。 但是无论如何我也想不到有一天，我会嫌弃jQuery minify 之后还有88K，然后自己把东拼西凑出来的代码发了个库。 see https://npmjs.org/package/pida，使用上基本和jquery是熟悉的味道:

Pida

Terribly small javascript library ,up to 5k (gziped)

• Chrome or other supported:( no IE )
• Browser side only,not for node.js

Installation:

yarn add pida

or

npm install --save pida

Example of document query

import  pida from  'pida'
pida.onDomReady(()=>{
    console.dir(pida.$("a").length)
     pida.addListener(pida.$("a"),"click",(evt)=>{
         console.log(evt.target);
     })
    pida.each(pida.$("a"),(item)=>{
        console.log(item);
    })
    console.dir(pida)
})

vite demo project:https://github.com/gotapi/pida-demo

ajax get request

pida.get("https://ip4.dev/myip?format=json",{
    "on":{
        "load":(progress)=>{
            console.log("onload")
        },
        "loaded":(progress)=>{
            console.log("onloaded")    
        }
    }
}).then((data)=>{
    console.log(data);
}).catch((err)=>{
    console.log("got error")
    console.log(err);
});

ajax post request

let data = new FormData()
data.append("title","hello")
pida.post("https://example.org/",{
    headers:{
        "secret":"this is secret"
    }
    },
    data
).then((resp)=>{
    console.log("got resp:")
    console.log(resp)
}).catch((err)=>{
    console.log("got error")
    console.log(err)
});

example for post x-www-form-urlencoded data:

let formSend = "type=json&url=" + encodeURIComponent(location.href) + "&content=" + encodeURIComponent("Hellobaby");

pida.post("https://gotapi.net/v3/api/text2pic", {
    "timeout": 15000,
    "headers": {
        "secret": secret,
        "Content-Type": "application/x-www-form-urlencoded"
   }
},
formSend).then((data) => {});

hide/show/toggle

pida.$("a[href]").toggle()

html/val/text

pida.$("p").html("same text")

attr

//when you try to getAttributes,return the first
pida.$("input").attr("value")
pida.$("href").attr("link","/index")

addClass/removeClass

pida.$("p").addClass("bigger")
pida.$("p").removeClass("blue-text")

usage of event binding

    pida.$("a[href]").on("click", (evt) => {
        evt.preventDefault();
        console.log(evt.target.getAttribute("href"));
    });

chainable

pida.$("a[href]").on("click",(evt)=>{ console.log(evt);}).addClass("blue").addClass("bigger")

other helpers

pida.each(iter,(element)=>{

})
pida.isArray()
pida.isObject()
pida.isString()
