Client side validation

34 Views

Hi,

I am trying to use the invalid property of an input field (in javascript) to decide whether to post a form to the server. My elements are:

<hbj:form id="myFormId"

method="post"

encodingType="multipart/form-data">

<hbj:inputField

id="datefield"

type="DATE"

maxlength="10"

design="STANDARD"

jsObjectNeeded="true"

showHelp="TRUE">

</hbj:inputField>

<hbj:button

id="go"

text="Go"

onClientClick="if(!CheckDate(this))htmlbevent.cancelSubmit=true;"

onClick="go">

</hbj:button>

</hbj:form>

And then I have my javascipt validation:

function getElement(id){

return document.getElementById(

eval(htmlb_formid + "_htmlbElements['"id"'];"));

}

function getElementState(id){

return document.getElementById(

eval(htmlb_formid + "_htmlbElements['"id"'].isvalid;"));

}

function getValueOfElement(id){

var value = parseFloat(getElement(id).value);

return isNaN(value)?0:value;

}

function getStatusOfElement(id){

var val1 = parseFloat(getElement(id).valid);

var val1 = getElement(id).value;

var val2 = getElement(id).isvalid;

var val3 = getElement(id).invalid;

if (val1 == 0){

return 0;

}

else{

return(val1 + " " + val2 + " " + val3);

}

}

function CheckDate(PageTitle1){

var myEl2 = getValueOfElement('datefield');

alert(myEl2);

var myEl3 = getStatusOfElement('datefield');

alert(myEl3);

var myEl5 = getElementState('datefield');

alert(myEl5);

var myEl4 = getElement('datefield').type;

alert(myEl4);

}

-


I know its a bit mashed together there but the getStatusOfElement should be able to see if the invalid property is true or not.

Please help??

Logically what I want to do is say: if the invalid property for the textbox is true then don't submit the form to the server.
