javascript - Can someone help with this self invoking function stuff? -

-

I was trying to debug this script all day and I have not found anything that much help was appreciated Will go.

I get an error that it is a curly brace or a square brace or a parent is missing and whenever I try to get the value of my options, it is said that x is undefined , But when I input 0 as my index, I can retrieve the opts.value, my question is why x is undefined and what is missing from this script

Prices = (function () {table = document.getElementsByTagName ("Table"); Select = Table [0] .getElementsByTagName ("Select"); (var x = 0; x & lt; = 10; x + +) Opts = new array (); opts = selects [x] .getElementsByTagName ("option") [select [x]. Selectedindex];} return {value: (function () {val = new array}; Var i = 0; i

OK, if that script & lt; Head & gt; Trying to prepare the DOM elements of your document before reading it, unless you are calling it through onload, which you are not showing.

Your second option is & lt; Script & gt; ... & lt; / Script & gt; Just before the closing body on the bottom of my page, though I can not believe 100% that this problem is because you have not posted your HTML, it is a fair estimate if you are getting undefined DOM elements.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
