How to get h:inputText value into java script

Question

I have 3 date input fields when the page loads first time those fields values are "null" and by default i am putting with some dates by using onload function
function runOnLoad()
     var v1 = document.getElementById(document.getElementById("recordedDateProxy").value);
     var v2 = document.getElementById(document.getElementById("mystartingDateProxy").value);
     var v3 = document.getElementById(document.getElementById("myLastDateProxy").value);
     var v4 = document.getElementById(document.getElementById("reportsTypeProxy").value);
     if (v1 == null && v2 == null && v3 == null && v4 == null)
setDate();
          setTwoDate();
then,i am putting one date and making remaining two dates null (i.e disable two dates) when the page loads second time it was giving all the date fields null. But i know there is a value in one date field. but it was not taking that value so it was again calling setDate();
setTwoDate();
please help me

Answer 1

no there are only 3 date fields and laso one is a radio button value. what i am doing is
I have a jsp page in that 3 date fields are there and two radio buttons one is day type and one is month type if i choose day type radio them two date fields disable if i choose month type them first date field disable. ok
i have a button which get reports and print them in the same page so when the page loads first time then u can see in first date field todays date and remaining two date fields fill with starting date and ending date ok because i am calling onload function in onload function i an getting the values of these fields when those are null them fill with dates
after fetching the records page loads again and calling inload function again then it was againg taking all the fields null it was not taking the date what i have enterd thats y it was again putting the dafault values
