I used cdn url for jquery it didnt work ,network connection was stable.simple alert() function onclick on the p tag was working until i wrote that alert function call in the script tag

CodePudding user response：

You've created an infinitely recursive function here:

function alert() {
  alert("hello");
}

When you call alert(), it internally calls alert(), which internally calls alert(), which internally calls alert(), and so on forever.

You don't need to write an alert function in the browser. It already has one. Just remove this function of yours entirely.

Additionally, a string has no function called click:

("p").click(/*...*/)

You're probably looking to use that string as a jQuery selector:

$("p").click(/*...*/)

Also, don't use inline click handlers:

<p onclick="alert()">

Remove the handler from there:

<p>

And, since you're using jQuery, just use jQuery to attach a click handler:

$("p").click(/*...*/)

Overall, it sounds like the click handler you want is simply:

$("p").click(function() {   
  $(this).hide();
  alert("hello");
});

(Which should, in this structure, still remain inside your document's ready handler.)
