javascript - Uncaught TypeError: Cannot set property 'value' of null

I'm trying to pass the entered text to the controller using an ajax request. But i'm getting athe error "Uncaught TypeError: Cannot set property 'value' of null " when I tried to execute JS file..

Here is the HTMLcode:

<form action="">
    <input type="text" class="searchbox1" name="search" placeholder="Search for Brand, Store or an Item..." value="text" />
    <input type="button" class="searchbox_submit1" name="submit" value="text" onClick="javascript:getSearchText();">
</form>

Here is the JS code:

function getSearchText() {
    var searchText = document.getElementByName("search").value;
    h_url=document.getElementById("u").value;
    var theURL = h_url+'search_all/' + deptid + '/' + searchText + '/1';
    $.ajax({
        url : theURL,
        fail: function(){
        },
        success : function() {
        },
        error:function(){
        }
    });
}

Please help me to fix this.

You don't have an element with the id u.That's why the error occurs. Note that you are trying to get the value of the input element with the name 'u' and it's not defined in your code.
