在函数中获得值

Question

我想获取申报值id_log关于数组函数到var id_L，那该怎么办？

function editcashiersession(id_log,d,e){ 
    var vdt = $('h_dttm').value; 
    var vdt2 = $('h_dttm2').value; 
    var tbd = _gel('tblcashiersession'); 
    var tr = d.parentNode.parentNode; 
    **var id_L = ('id_log');** 
    var curcashiersessioneditorid = _gel('rowcashiersession'); 

    if (lastcashiersessioneditorid) { 

    _destroy(lastcashiersessioneditorid); 

     if (lastcashiersessioneditorid == curcashiersessioneditorid) { 

      lastcashiersessioneditorid = null; 
      d.value = 'Edit Log'; 
      _gel('sessi_errmsg').innerHTML = ''; 
      return; 
     } 
} 

Answer 1

var id_L = id_log; 

这就是你想要的东西，而不是

var id_L = ('id_log'); 

并仔细检查你的JavaScript，因为你没有if语句关闭一个：

function editcashiersession(id_log,d,e){ 
    var vdt = $('h_dttm').value; 
    var vdt2 = $('h_dttm2').value; 
    var tbd = _gel('tblcashiersession'); 
    var tr = d.parentNode.parentNode; 
    var id_L = id_log; 
    console.log(id_L); //delete this line after testing. 
    var curcashiersessioneditorid = _gel('rowcashiersession'); 

    if (lastcashiersessioneditorid) { //You forget to close this if 

    _destroy(lastcashiersessioneditorid); 

    if (lastcashiersessioneditorid == curcashiersessioneditorid) { 
     lastcashiersessioneditorid = null; 
     d.value = 'Edit Log'; 
     _gel('sessi_errmsg').innerHTML = ''; 
     return; 
    } 
    } // I added this in order to close it 
} 

而且，lastcashiersessioneditorid不在你的代码上设置。
