You can use onclick to run some JavaScript or jQuery code before submitting the form like this    lt script type  text javascript  gt      beforeSubmit   function            if  1    1                 your before submit logic                               formid   submit                       lt  script gt   lt input type  button  value  Click  onclick  beforeSubmit       gt

Assuming you have a form like this    lt form id  myForm  action  foo php  method  post  gt      lt input type  text  value      gt      lt input type  submit  value  submit form    gt    lt  form gt    You can attach a onsubmit-event with jQuery like this       myForm   submit function       alert  Handler for  submit   called       return false        If you return false the form won t be submitted after the function  if you return true or nothing it will submit as usual   See the jQuery documentation for more info

make sure the submit button is not of type  submit   make it a button   Then use the onclick event to trigger some javascript   There you can do whatever you want before you actually post your data
