How to pass parameter to jQuery document.ready() function (jstl, MVC, java)

in my .jsp file I have code like this (to the point)

<td width="200px">
  <input type="text" id="${general.pk.code }_${MTPL[4].pk.run}"
  name="${general.pk.code }_${MTPL[4].pk.run}"
  value="${MTPL[4].value}" onChange="gg('${MTPL[4].jsCode }','${MTPL[4].pk.code }',this,'${MTPL[4].operator }','${MTPL[4].param1 }','${MTPL[4].param2 }','${MTPL[4].param3 }','${MTPL[4].param4 }','${MTPL[4].param5 }','${MTPL[4].pk.run }','${MTPL[4].param6 }','${MTPL[4].param7 }')"
  style="text-align: right;">
</td>

<c:forEach items="${valueRun }" var="generalR">
  <td width="200px">
    <input type="text" id="${general.pk.code }_${generalR}"
    name="${general.pk.code }_${generalR}"
    value="" onChange="gg('${MTPL[4].jsCode }','${MTPL[4].pk.code }',this,'${MTPL[4].operator }','${MTPL[4].param1 }','${MTPL[4].param2 }','${MTPL[4].param3 }','${MTPL[4].param4 }','${MTPL[4].param5 }','${MTPL[4].pk.run }','${MTPL[4].param6 }','${MTPL[4].param7 }')"
    style="text-align: right;">
  </td>
</c:forEach>

when page finish load, the value be like this (inspect element)

input type="text" id="MTPL_4" name="MTPL_4" value="1100" onchange="gg('COPAS','MTPL_4',this,'','this','','4','','','4','','MTPL')" style="text-align: right;">

I want to get parameter on function gg() at javascript document ready. How to do that.

<script>
  $(document).ready(function() {
    var a = $("#MTPL_4").val(param1); //didnt get param1 value
  });
</script>

I try .val() but its only get value (1100). How get value inside onchange function gg(); (try to get "COPAS",'MTPL_4', etc)

You can use jquery attr method for this and then get substring out of it like below:

$(document).ready(function(){
    var len = $("#MTPL_4").attr("onchange").length;
    alert($("#MTPL_4").attr("onchange").substring(3, len-1));
})

Further if you want to split the string and get individual parameter which is separated by "," you can use split method.
