How to replace window.open(...) with a POST
html, javascript
Solution
In fact I made a small "library" for this, open in POST a new window :
// Arguments :
// verb : 'GET'|'POST'
// target : an optional opening target (a name, or "_blank"), defaults to "_self"
window.io = {
open: function(verb, url, data, target){
var form = document.createElement("form");
form.action = url;
form.method = verb;
form.target = target || "_self";
if (data) {
for (var key in data) {
var input = document.createElement("textarea");
input.name = key;
input.value = typeof data[key] === "object"
? JSON.stringify(data[key])
: data[key];
form.appendChild(input);
}
}
form.style.display = 'none';
document.body.appendChild(form);
form.submit();
document.body.removeChild(form);
}
};
Example :
io.open('POST', 'fileServer.jsp', {request: {key:"42", cols:[2, 3, 34]}});
To open in a new window, set the `target` parameter :
io.open('POST', someURL, someArgs, 'newwin');
or to ensure it's a new window/tab each time :
io.open('POST', someURL, someArgs, '_blank');
Problem
I currently have some code that runs a `window.open(urlWithGetParams)` line. As far as I'm aware, this is going to force me to use a `GET` request. I would like to do this with a POST request. Is there a workaround for this? I'm not married to `window.open()`, either. I'm open to just about any alternative that allows me to spawn a new window via a POST request instead of a GET.
