Compatible with IE and Firefox versions of js inverse selection, select all, multi-select box_form effects

Friends say it's not compatible. Last night I went back and debugged a compatible version:

Copy code The code is as follows:

Select all <meta http-equiv="Content-Type" content="text/html; charset=gbk"> Reverse election Item1 Item2 <form name="bdkey" id="bdkey"> Item3 <p class="STYLE1"> Item4 <input type="checkbox" name="selectAll" value="checkbox" onclick="selectIt('selectAll')"> Item5 <input type="checkbox" name="invest" value="checkbox" onclick="selectIt()"> <input type="checkbox" name="checkbox" value="checkbox"> <input type="checkbox" name="checkbox" value="checkbox"> <input type="checkbox" name="checkbox" value="checkbox"> <input type="checkbox" name="checkbox" value="checkbox"><input type="checkbox" name="checkbox" value="checkbox"></p> </form> [Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute
