generating textfields dynamically

hiii,

i have a doubt.

if i write

<input name="<%=abcd%>" type="text" value="" size="6" class="TxtBox">

here the text field name comes dynamically. the name can vary.

i have to find the length of the particular name.

suppose the textfield contains 3 names namely CCA,HRA,XYZ.These 3 are coming from array list .i have to find the length of the each field individually.how can i get it.

i did like this.

i have passed name and index in the function like

fnTest('<%=abcd%>','<%=index%>')

in function it is displaying names.but how to fund the length i am not getting.

if any body knows tell me.

i don't know the names .the names may change.some times it might be CCA.some can add new fields also.

so i can't take them as a fixed one.

the name that i am passing contains any number of names like cca,hra,..etc.they are not fixed.it may contain these names or it might not.

that's why i have to find all the length of the fields that are generated.

hii,

thanx

i am not getting the above one. can u guide me.

first the earnings names are taken in a bean like

hmBean.put("alEmpHmEarnings",alEmpHmEarnings);

next the names occur with

strEarHeaderName=(String)((HashMap)alEmpHmEarnings.get(i)).get("er_name");

in jsp like above the code is written by checking some conditions.

hence the strEarHeaderName may contain either one earning,or no earnings,or more than one earning.

that earning may be any one.Depending on the conditions it will display CCA,or HRA or TAW

it can also display only one like CCA and the like

and the text is written like

<input type="text" name="<%=strEarHeaderName%>" value="" size="6" clas="TxtBox">

i tried like this,

<input type="text" name="<%=strEarHeaderName%>" value="" size="6" clas="TxtBox" onClick="fnTest('<%=strEarHeaderName%>','<%=index%>'>

the index is taken above .it is incrementing

function fnTest(earname,str)

{

alert(earname);

alert(str);

alert(form1.earname.length);

}

it is displaying earname,str.

But it is not displaying the 'earname.length'

how i can get the length of the earname.

the earname contains more than one name.

can u tell me how can i get the length of the each earning individually

and also total length.">

hii,

use

alert([b]eval[/b]("document.[b]form1[/b]."+earname+".value.length"));

if form1 is ur form name.

From my understanding earname getting only one value per time.

in ur post, mentioned about total length. what is that?

May i know the Logic behind this?

total length means if earnings are of more than 2 like earnings of an employee can be in the form like child care allowance(CCA),

house rent allowance(HRA) ,Travel Allowance(TAW) like that.

Based On the person's salary his earnings will be there.

for some employees company can pay travel allowance,houserent allowance..etc

and for some it may not.

if employee contains earnings like CCA and HRA and TAW,then these three names of textfields are dynamically generated and the names can get through<%=strEarHeaderName%>.From this i have to identify the names and i have to find the lengths.

total length means the length of CCA,HRA,TAW .

suupose there are 3 textfields for the three then the length should be displayed as 9.

(or)

for individually it should be displayed as 3 for the earning name that is displayed.
