使用JQuery通过页面URL搜索页面中的值

//This Script check if "Qassas" exist in the table or not
if( $('#T1 td:contains("Qassas")').length  > 0)
{
  alert("Qassas exist");
}else
{
  alert("Qassas doesn't exist");
}

//This script retrieve the values of the closest "td" tags

var tr=$('#T1 td:contains("Qassas")').parent();
var values=[];
tr.children().each(function(){
  values.push($(this).text());
});
console.log(values);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="T1">
    <tbody>
    <tr>
    <td>Qassas</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>

    <td>test</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
