Javascript inserting data into HTML table
This is a rather simple question, I am having problems inserting data from Javascript into an HTML table.
Here is an excerpt of my JavaScript:
UPDATED - I got rid of the two loops and simplified it into one, however there is still a problem..
for (index = 0; index < enteredStrings.length; index++) {
开发者_如何转开发 output.innerHTML += "<td>" + enteredStrings[index] + "</td>"
+ "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
And here is an except of my HTML page:
<table id="nameTable">
<tr>
<th>First</th><th>Last</th>
</tr>
Updated Picture:
Try this (edited):
var tableContent = '<tr>';
for (index = 0; index < enteredStrings.length; index++) {
tableContent += "<td>" + enteredStrings[index] + "</td>";
nameCounter++; // I don't know if this should be there,
// logically the counter should be incremented here as well?
total.innerHTML = "Total: " + nameCounter;
}
tableContent += '</tr><tr>';
for (index = 0; index < enteredStringsTwo.length; index++) {
tableContent += "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
tableContent += '</tr>';
output.innerHTML += tableContent;
Edit2 (for updated question code):
var tableContent = '<tr>';
for (index = 0; index < enteredStrings.length; index++) {
tableContent += "<td>" + enteredStrings[index] + "</td>"
+ "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
tableContent += '</tr>';
output.innerHTML += tableContent;
Edit3 (after looking at the code sent in email):
var tableContent = "";
for (index = 0; index < enteredStrings.length; index++) {
tableContent += "<tr><td>" + enteredStrings[index] + "</td>"
+ "<td>" + enteredStringsTwo[index] + "</td></tr>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
output.innerHTML = tableContent;
instead of closing the td you are opening new ones try
for (index = 0; index < enteredStrings.length; index++) {
output.innerHTML += "<td>" + enteredStrings[index] + "</td>";
total.innerHTML = "Total: " + nameCounter;
}
for (index = 0; index < enteredStringsTwo.length; index++) {
output.innerHTML += "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
UPDATE: you are appending the html to the table instead of the row. in this case, the browser created a row for you automatically after the each td is appended.
With slight modifications in your code,
var outputTbl = document.getElementById('nameTable');
var output = document.createElement("tr");
outputTbl.appendChild(output);
for (index = 0; index < enteredStrings.length; index++) {
output.innerHTML += "<td>" + enteredStrings[index] + "</td>";
total.innerHTML = "Total: " + nameCounter;
}
for (index = 0; index < enteredStringsTwo.length; index++) {
output.innerHTML += "<td>" + enteredStringsTwo[index] + "</td>";
nameCounter++;
total.innerHTML = "Total: " + nameCounter;
}
If you need to add inner html code here.
<table id="nameTable" style="width:300px;">
<tr>
<th>First</th><th>Last</th>
</tr>
</table>
You can use Jnerator in this case.
If this is your data:
var data = [
{ first: 'Cole', last: 'Alan'},
{ first: 'Michael', last: 'Scott'}
]
You can add them to you table in next way:
for(var i=0; i<data.length; i++) {
var item = data[i];
var row = $j.tr({ child:[$j.td(item.first), $j.td(item.last)] });
nameTable.appendChild(row.dom());
}
nameTotal.innerHTML = 'Total: ' + data.length;
This is example.
