The code is as follows:
Untitled document
_ window.onload = function () {
Var oBtn = document.getElementById ('btn')
OBtn.onclick = function () {
/ / 1. Create an ajax object
/ / only non-IE6 browsers are supported
Var oAjax = null
If (window.XMLHttpRequest) {
OAjax = new XMLHttpRequest ()
/ / alert (new XMLHttpRequest ())
} else {
/ / only IE6 browsers are supported
OAjax = new ActiveXObject ("Microsoft.XMLHTTP")
}
/ / 2. To connect to the server, add a time parameter here. Each access address is different, so the browser does not need the buffer in the browser, but
/ / but the server does not resolve this time.
OAjax.open ("get", "a.txtbuttt =" + new Date () .getTime (), true)
/ / 3. Send
OAjax.send (null)
/ / 4. Accept information
OAjax.onreadystatechange = function () {
/ / where is the interaction between the browser and the server? when it is equal to 4, it means that the reading is completed.
If (oAjax.readyState==4) {
/ / status code, which is only equal to 200, which means that the acceptance is complete and successful.
If (oAjax.status==200) {
Alert ("success" + oAjax.responseText)
} else {
Alert (failure)
}
}
}
}
}
