How to run this script correctly to display the table in runtime?
I am trying to display a table with data in runtime using script. I called the script from table header. Is that possible to call a function from table header.
</HEAD>
<BODY>
<TABLE id="dataTable" width="350px" border="1" onload="start('dataTable');">
<TR>
<THEAD>
<TR>
<TH>Select</TH>
<TH>Id</TH>
<TH>Name</TH>
<TH>Age</TH>
<TH>Dept</TH>
<TH>Option</TH>
</TR>
</THEAD>
</TABLE>
</BODY>
</HTML>
The Script is
function start(dataTable) {
var data = new Array();
var id;
var name;
var age;
var dept;
data[0].id = "1";
data[0].name = "Tamil";
data[0].age = "23";
data[0].dept = "CSE";
data[1].id = "1";
data[1].name = "Tamil";
data[1].age = "23";
data[1].dept = "CSE";
data[2].id = "1";
data[2].name = "Tamil";
data[2].age = "23";
data[2].dept = "CSE";
for (var i = 0; i<data.length; i++)
{
var table = document.getElementById(tableID);
var rowCount = data.length;
var row = table.insertRow(rowCount开发者_开发百科);
//Check box
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
cell1.appendChild(element1);
//ID Column
var cell2 = row.insertCell(2);
cell2.innerText = data[i].id;
//Name Column
var cell3 = row.insertCell(3);
cell3.innerText = data[i].name;
//Age Column
var cell4 = row.insertCell(4);
cell3.innerText = data[i].age;
//Dept Column
var cell5 = row.insertCell(5);
cell5.innerText = data[i].dept;
//Button Column
var cell6 = row.insertCell(6);
var element2 = document.createElement("input");
element2.setAttribute("type", "button");
element2.setAttribute("id", "dataRow"+id);
element2.setAttribute("value", "Edit");
cell6.appendChild("element2");
}
}
The output is just the Headers. I cant get the data into table.
Thanks for suggestions in advance.
width="350px"
px
is CSS. No px
when using the HTML attribute.
onload="start('dataTable');"
There is no load
event on <table>
, this will never be called. Put a <script>
element after the table to call the function.
var data = new Array();
For sanity, use []
array literal syntax:
var data= [
{id: 1, name: 'Tamil', age: 23, dept: 'CSE'},
...
];
var id; [and name etc.]
You never use these variables. Declaring var
s has nothing to do with members of an object.
document.getElementById(tableID)
You called that variable dataTable
not tableID
.
cell2.innerText = data[i].id;
innerText
is a non-standard IE extension. Consider using the standard textContent
property first, if available, or just use plain old cell2.appendChild(document.createTextNode(data[i].id));
, which is supported more widely than either.
element2.setAttribute("type", "button");
Never use getAttribute
/setAttribute
in an HTML document, there are bugs in it in IE. Instead use the DOM Level 2 HTML properties, which are easier to read anyway. element2.type= 'button';
.
cell6.appendChild("element2");
That's a string, not the variable element2
.
Just call your script in a <script>
tag after </table>
. Your script should be able to see the table elements because they're alreadyy loaded
