有沒有辦法跟蹤JavaScript的點擊？

Question

我正在基於javascript函數填充表格。我想限制輸入的數據爲2，之後我隱藏表格。有沒有一種方法可以追蹤javascript代碼被擊中的次數？

function addNewRow() { 
    $('#displayInjuryTable tr:last').after('<tr><td style="font-size:smaller;" class="name"></td><td style="font-size:smaller;" class="address"></td></tr>'); 
    var $tr = $('#displayInjuryTable tr:last'); 
    var propertyCondition = $('#txtInjuryAddress').val(); 


    $tr.find('.name').text($('#txtInjuryName').val()); 
    if (propertyCondition != "") { 
     $tr.find('.address').text($('#txtInjuryAddress').val() + ', ' + $('#txtInjuryCity').val() + ' ' + $('#txtInjuryState').val() + ' ' + $('#txtInjuryZip').val()); 
} 

Answer 1

var someCounter = 0 

function addNewRow() { 
    if(someCounter>1) { 
    return 
    } 
    someCounter++ 
...your code... 
} 

Answer 2

var addNewRow = (function(){ 
    var count = 0; 
    return function(){ 
     if (++count === 2) { 
      //hide feature 
      return; 
     } 
     ... // your code here 
    } 
})();
