Here is your required solution using onChange event
I have taken a function when range is changed,
<input type="range" id="blurValue" class="blurValue" min="0" max="100" step="1" onChange="changed()"></input>
function changed()
{
var obj = document.getElementById('imgBlur');
obj.style["-webkit-filter"] = "blur("+document.getElementById("blurValue").value+"px)";
}
This catches the range change event and changes the css using javascript
obj.style["-webkit-filter"] = "blur("+document.getElementById("blurValue").value+"px)";
