I am working on a personal project in Javascript to allow people to create a table of "dream plays" in Scrabble. Here is the link: http://psyadam.neoclaw.net/tables8.html
I am currently trying to allow the user to edit a dream play.
Here is my code:
function editRow(e)
{
var eventEl = e.srcElement || e.target,
parent = eventEl.parentNode
parent = parent.parentNode
var test = $(parent.cells[0]).text()
$('tr').each(function(){
$(this).children("td:contains(test)").each(
function()
{
pageEnd.innerHTML += "success"
$(this).addClass('selected')
}
)
})
pageEnd.innerHTML += test
//pageEnd.innerHTML += $(parent.cells[3]).text()
insertRow()
}
// insertRow assumes that the correct row in the table has the "selected" class added to it
function insertRow()
{
var Row = $('<tr>').append(
$('<td>').append('<input id="input1">'),
$('<td>').append('<select id="input2"><option value=""></option><option value="Yes">Yes</option><option value="No">No</option></select>'),
$('<td>').append('<select id="input3"><option value=""></option><option value="Natural">Natural</option><option value="1 Blank Used">1 Blank Used</option><option value="2 Blanks Used">2 Blanks Used</option></select>'),
$('<td>').append('<select id="input4"><option value=""></option><option value="vs Computer">vs Computer</option><option value="Online Game">Online Game</option><option value="Friendly Game">Friendly Game</option><option value="Club Game">Club Game</option><option value="Tournament Game">Tournament Game</option></select>'),
$('<td>').append('<input id="input5">')
)
$("#myTable tr.selected").after(Row)
}
Right now I'm just trying to get my code to insert a row into the table. I am trying to do this by using the code $(this).addClass('selected')
to tag the row the user selected and then use it in my insert function to insert a row. However, nothing seems to happen. I am using pageEnd.innerHTML += "success"
as a debugging tool to see if it is even getting there. Unexpectedly, it prints success twice when it should only print once, as in the test I ran every word was unique.
In any case I can't figure out why it's not working. Any help is appreciated. Thanks, ~Adam
Try this:
function editRow(e) {
var eventEl = e.srcElement || e.target,
parent = eventEl.parentNode
parent = parent.parentNode
var test = $(parent.cells[0]).text()
$('tr').each(function(){
var outerThis = this;
outerThis.children("td:contains(test)").each(
function()
{
pageEnd.innerHTML += "success";
$(this).children().css('text-align', 'center');
}
)
})
pageEnd.innerHTML += test
//pageEnd.innerHTML += $(parent.cells[3]).text()
insertRow()
}
I set the outer this
to a variable which you can use. Also textAlign
is not a jQuery function. You need to use .css()
and then specify text-align
in that.
You have two options to achieve this:
The first one as the others are suggesting ie by keeping a variable of outer this
and then using this:
$('tr').each(function() {
var outerThis = this;
// inside another loop (not sure about children method, just an example)
$(outerThis).children("td:contains(test)").each(function() {
// do something with outerThis to operate on further
});
});
Another option to use Javascript's bind()
method:
$('tr').each(function(i, trElement) {
// this == trElement
// inside another loop
$(outerThis).children("td:contains(test)").each(function(index, tdElement) {
$(this) // will be now tr element
$(tdElement) // will be td element
}.bind(this));
});
