JavaScript的作品在1.5，但在的Joomla不起作用2.5

Question

下面的JavaScript和功能完美無瑕的作品中的Joomla 1.5，但似乎它並沒有在2.5的工作 - 任何度假。它的一個資格計算器

似乎驗證不工作因爲每當表單提交 - 驗證是沒有得到2.5執行，PHP 5.3

<td><input name="calc" type="button" class="red-btn" onClick="javascript:return(validate())" style="width:65" value="Calculate Eligibility" /> 
    <input type="reset" name="reset" value="Reset" class="red-btn" /></td> 

我不能夠點擊提交，即使我點擊沒有反應

下面是這是腳本稱爲

function validate() 

{ 
var income,Coapplnincome,vOtherLonAmt,deduct,IntRate,LoanTenure; 
var totInterest,totemi,ElgibleLon; 
if(!document.eligib_calc.income.value)

    document.eligib_calc.income.focus(); 
    return false;

    document.eligib_calc.income.focus(); 
    return false;

腳本將起作用。但提醒您在使用jQuery兩種方式

1）http://docs.joomla.org/JDocument
http://docs.joomla.org/JDocument/addScriptDeclaration
或
2）顯示您的警報indise標籤

例子：

function getJavaScript($message) { 
$javascript .= 'if(window.addEventListener){ // Mozilla, Netscape, Firefox' . "\n"; 
$javascript .= ' window.addEventListener("load", function(){ alert("' . $message . '");}, false);' . "\n"; 
$javascript .= '} else { // IE' . "\n"; 
$javascript .= ' window.attachEvent("onload", function(){ alert("' . $message . '");});' . "\n"; 
    $javascript .= '}'; 
    return $javascript; 
} 

$doc =& JFactory::getDocument(); 
$doc->addScriptDeclaration(getJavaScript('This will appear in an alert box after the page loads.'));
