How to show multiple variables in a single alert?
Alert command assumes this structure:
alert (variable)
No, alert()
assumes this structure:
alert(some expression)
...where "some expression" is pretty much any JavaScript expression - if the expression is not a string it will be converted (though in some cases, eg, for some objects the result might not be very meaningful).
So:
alert(variable);
alert("string literal");
alert(variable1 + variable2 + variable3);
alert(variable1 + ", " + variable2);
alert(resultOfFunctionCall());
alert([1,2,3]);
alert(whatever() + "else" + you.can.think + "of");
Or even:
alert(); // displays "undefined"
Note that if you are trying to debug your code you are better off using console.log()
than alert()
. If you are trying to produce a dynamic message to show the user just concatenate variables as needed, eg:
alert("Hello there " + name + ". Welcome.");
Do you mean this :
alert (variable1 + ', ' + variable2);
No jQuery is required in this case.
The below is how to do it:
var a = "Hello";
var b = "World!";
alert(a + b);
This works for me:
window.alert = function (native) {
return function (str) {
var argsArray = Array.prototype.slice.call(arguments);
var s = "";
for (var i = 0; i < argsArray.length; i++) {
msg = argsArray[i];
if (typeof (msg) == 'object') msg = JSON.stringify(msg);
s += msg;
if (i < (argsArray.length - 1)) s += ', ';
}
native(s);
}
}(window.alert);
Try this:
alert("This", "That", {"this":"that"});
