JavaScript，onclick事件未响应

Question

I hope to get a simple and straight answer as this is driving me crazy. I know this isn't the best way of doing this but I just can't figure out, why these two lines behave differently:

First line, working fine:

<img id="hellig_del42736" src="../images/kryds.png" title="Slet helligdagen den 01-01-2017..." alt="Slet helligdagen den 01-01-2017..." onclick="if(confirm('Vil du slette helligdagen den 01-01-2017?')){document.getElementById('helligid42736').style.textDecoration='line-through';hasChanged=false;window.location.href='/admin/admin.asp?vacfrom='+(25569+(new Date(document.getElementById('feriefra').value).getTime()/1000/86400))+'&delbankhd=42736&page=2&sid=feriefra'}" onmouseover="this.style.cursor='pointer'" onmouseout="this.style.cursor=''">

Second line, not responding - sometimes resulting in "member not found-error" - sometimes works if debugging (F12) is open:

<img id="blockedip_del8" src="../images/kryds.png" title="Fjern blokeringen af IP# 5.6.7.8 (mail@mail.dk)..." onclick="if(confirm('Vil du fjerne blokeringen af IP# 5.6.7.8 (mail@mail.dk)?')){document.getElementById('blockid8').style.textDecoration='line-through';hasChanged=false;window.location.href='/admin/admin.asp?delblockedip={93F17D3B-7FA1-48F1-8792-K52E30273818}&page=5&sid=deadlinetime'}" onmouseover="this.style.cursor='pointer'" onmouseout="this.style.cursor=''">

I have tried several thing inside the comfirm()-statement (second line):

• Removed paranthesis with no difference
• Removed hashtag with no difference
• Ensured that there are no conflicting id's

These lines are to my best knowledge codewise identical yet they behave differently.

I know I can put all the statements in a function and that "I really shouldn't..." but if this is how I want it, how can I fix it?

Thanks,

Answer 1

I'm an idiot!

For some idiotic reason I had used id="confirm" on a form element within the same form and changing that reserved word to id="confirmation" solved everything.

I thought I checked everything but I hadn't. Only removing elements one by one and testing led to the error.

Thanks "idmean" for pointing me to the surrounding code.
