JavaScript compatibility with IE and Firefox

1.document.formname.item ("ItemName") problem

Note: Under IE, you can use Document.formName.item ("ItemName") or document.formname.elements["elementname"]; Firefox, you can only use the document.formname.elements["ElementName"].

Workaround: Unify the use of document.formname.elements["ElementName"]. TEXT1:

document.formName.item("itemName")　　　　
document.formName.elements["elementName"]

-------------------------------------------------

2. Collection Class object problem

Note: IE, you can use () or [] get the Collection class object; Firefox, you can only use [] to get collection class objects.

WORKAROUND: Use [] to get collection class objects uniformly.

TEXT2:

document.forms("formName")　
document.forms["formName"]　

TEXT3:

document.getElementsByName("inputName")(0)　
document.getElementsByName("inputName")[0]

-------------------------------------------------

3. Custom attribute Issues

Note: Under IE, you can get the custom attribute by using the method of obtaining the General property, or you can use GetAttribute () to get the definition attribute. Firefox, you can only use getattribute () to get the definition attribute.

Workaround: The unification is obtained from the defined attribute through GetAttribute ().

TEXT4:

Get the value of a custom property directly

A value derived from a defined property by GetAttribute ()

-------------------------------------------------

4.eval ("idname") problem

Note: Under IE, you can use either eval ("Idname") or getElementById ("Idname") to obtain an HTML object with an ID of idname; Firefox can only use getElementById ("Idname") to get an HTML object with an ID of idname.

Workaround: Unify the getElementById ("Idname") to get the HTML object with the ID idname.

Text5:
eval("idName")　　　　　　　　　　
document.getElementById("itemId")
