问题描述
为什么不起作用.我试图通过一些参数发生按钮的onclick时调用php文件.它会一直执行到jsfile.js中的alert语句为止.之后，ajax部分将无法执行..帮帮我..预先感谢..
why it isn't working. Am trying to call a php file when onclick of a button occurs with some parameters. It is getting executed till alert statement in jsfile.js. After that the ajax part is not getting executed.. Help me out.. Thanks in advance..
main.html
<!DOCTYPE html> <html> <head> <title></title> <script src="jsfile.js"></script> <script src="ajax.googleapis/ajax/libs/jquery/3.1.1/jquery.min.js"></script> </head> <body> <button onclick="cart(0)"> hi </button> <p id="disp"></p> </body> </html>jsfile.js
function cart(id1) { var id=id1; alert("enterd "+id); document.getElementById("disp").innerHTML ="hi"; $.ajax({ url:"/add.php ", type:"POST", data:{ item_id: id, }, success:function(response) { //document.getElementById("total_items").value=response; document.getElementById("disp").innerHTML =response; }, error:function(){ alert("error"); } }); }add.php
<?php if(isset($_POST['item_id']) && !empty($_POST['item_id'])){ //if(count($_POST)>0) echo "success"; exit(); } ?> 推荐答案在您的jsfile.js文件中，请更正我在以下代码中作为注释提及的以下几点.
In your jsfile.js file, please correct the following points which I have mentioned as comments on the following code.
function cart(id1) { var id=id1; alert("enterd "+id); document.getElementById("disp").innerHTML ="hi"; $.ajax({ url:"/add.php ", method:"POST", //First change type to method here data:{ item_id: "id", // Second add quotes on the value. }, success:function(response) { document.getElementById("disp").innerHTML =response; }, error:function(){ alert("error"); } }); }更多推荐
