jQuery append() not work in IE 7, IE8

Shame the MS IE bad ass once again trying to break down the web developers...

When you using jQuery .apend() function in IE 7 or 8, It will throw a error and break the web page function down.

for example the code below will throw an error and stop to continue execute the rest of the code after this line:
    elm.append("<elm2></elm2>");

There is a example can solve this problem which is using XML DOM.

var strXml = "<root>"
                       + "<publish>"
                       + "    <store>"
                       + "        <book title=\"How to fix IE\"/>"
                       + "    </store>"
                       + "</publish>"
                       + "</root>";
         
// Build XML document
var xDoc = $.parseXML(strXml);

// create new child element using XML Document
var xBook = xDoc.createElement("book");

// setting the attributes of child element using XML DOM method 
xBook.setAttribute("title", "How to fix bad ass IE!");

// setting the attributes of child element using jQuery
$(xBook).attr("authr", "Bill ...");

// Append child element to some where in the XML Document
var xStore = $(xDoc).find("store");
xStore.append(xBook);

The solution is append a div with clear and block style in the end of the other float inner div as below:
<div id="outer_div">
    <div class="float-style">Item 1</div>
    <div class="float-style">Item 2</div>
    <div class="float-style">Item 3</div>
    <div style="clear:both;display:block;"></div>
</div>

Solution 2: using overflow:auto; in the outer div style can also prevent outer div collapsed. But this method may cause outer div appear scroll bar when new div adding to it.
<div id="outer_div" style="overflow:auto;">
    <div class="float-style">Item 1</div>
    <div class="float-style">Item 2</div>
    <div class="float-style">Item 3</div>
    <div style="clear:both;"></div>
</div>

How to check which process using TCP/IP Ports in Windows

Run the following command from a command prompt to find the PID of the process which is using TCP port 80 and/or 443. 
   
    netstat -aon | find ":80" 
    netstat -aon | find ":443"

You will see an output similar to the following. Remember the actual PID will vary from case to case.
    TCP    0.0.0.0:80    0.0.0.0:0    LISTENING    3604 
    TCP    0.0.0.0:443   0.0.0.0:0    LISTENING    3320

Now using Task Manager you can easily find out to which process the above PID belongs and take appropriate action.
