Javascript error?! - part II
Ik had enige tijd geleden een vraag betreffende een Javascript error geplaatst op PHPHulp...een gedeelte daarvan is inmiddels opgelost.
Maar de complete oplossing heb ik echter nog niet.
Op de genoemde regel staat het volgende:
Code (php)
1

5

5
6
7
32 // Initialize the accordions
33 //
34 initialize: function(container, options) {
35 if (!$(container)) {
36 throw(container+" doesn't exist!");
37 return false;
38 }
33 //
34 initialize: function(container, options) {
35 if (!$(container)) {
36 throw(container+" doesn't exist!");
37 return false;
38 }
...ik weet echt niet wat ik nu moet doen (met ook de antwoorden van mijn vorige bericht in het achterhoofd).
Imenad een verlossend antwoord?

33 //

35 if ($(container) == false ) {
36 throw(container+" doesn't exist!");
37 return false;
38 }
Dus iets minder verkort?
En $(container) lijkt mij 'onjuist', maar dat zal wel zijn omdat ik geen Javascript spreek.
Waarschijnlijk moet je via catch() je exceptie die je opwerpt via throw() nog afvangen...

Jouw wijziging helpt ook niet echt...
En Rens...die W3C Schools uitleg toepassen op het volgende:

...waar doe ik dat?
Al mijn pogingen eindigen in alleen maar meer foutboodschappen...en die gaan voornamelijk over de 'syntaxis'...omdat ik niet exact weet waar ik de zg. 'catch' toe moet voegen.
Jij suggesties?

Vreemd hoe sommige vragen op Fora gesteld worden en daarna in de vergetelheid raken...of nooit beantwoord worden.
