Hello,
My code below echo's out the table in JSON format. Then beside each row, it shows a edit button. When the edit button is clicked, then a modal pops up with the information row. When I hit submit, it makes a ajax request to my database. I want to have the cell show the update, without refreshing the page.
$(function () {
function filterRender(ui) {
var val = ui.cellData,
filter = ui.column.filter;
if (filter && filter.on && filter.value) {
var condition = filter.condition,
valUpper = val.toUpperCase(),
txt = filter.value,
txt = (txt == null) ? "" : txt.toString(),
txtUpper = txt.toUpperCase(),
indx = -1;
if (condition == "end") {
indx = valUpper.lastIndexOf(txtUpper);
//if not at the end
if (indx + txtUpper.length != valUpper.length) {
indx = -1;
}
}
else if (condition == "contain") {
indx = valUpper.indexOf(txtUpper);
}
else if (condition == "begin") {
indx = valUpper.indexOf(txtUpper);
//if not at the beginning.
if (indx > 0) {
indx = -1;
}
}
if (indx >= 0) {
var txt1 = val.substring(0, indx);
var txt2 = val.substring(indx, indx + txt.length);
var txt3 = val.substring(indx + txt.length);
return txt1 + "<span style='background:yellow;color:#333;'>" + txt2 + "</span>" + txt3;
}
else {
return val;
}
}
else {
return val;
}
}
