Can you explain the process of using ajax to send POST requests to the server rather than GET?
Can you explain the process of using ajax to send POST requests to the server rather than GET?
It seems like you are directly working with the XHR object, so creating a 'postRequest' function can simplify your code:
To make this function work, you'll need to provide the url, the parameters to send (params), along with two callback functions: success, which will receive the responseText upon successful completion of the request, and error, which will handle errors by receiving the XHR object and status text:
function postRequest(url, params, success, error) {
var xhr = window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") :
new XMLHttpRequest();
xhr.open("POST", url, true);
xhr.onreadystatechange = function(){
if (xhr.readyState == 4) {
if (xhr.status == 200) {
success(xhr.responseText);
} else {
error(xhr, xhr.status);
}
}
};
xhr.send(params);
}
If you're struggling to transition from a GET request to a POST request, it might be time to dive into some Ajax resources. Understanding this basic concept is essential in mastering Ajax:
To use pure javascript, include POST as the initial argument in the xmlhttp.open() function:
xmlhttp.open('POST', 'example.php', true);
If you want to accomplish this, jquery can help:
$.post("sendingPage.php", { data: "Value 1", info: "Value 2" }, function(output){
alert("Reply from sendingPage: " + output);
});
Consider exploring the YUI connection manager as a potential jQuery alternative. With this tool, you can execute an ajax POST request by utilizing the following code:
YAHOO.util.Connect.asyncRequest('POST', 'php/post.php', callback, "new=1&old=2");
