Highlight cell value on doubleclick for copy

问题:

I have a jqGrid. I would like to highlight a particular cell from a row, ondbClickRow. This would make the task of copying the value of a cell onto clipboard, easy for users. Can someone guide me on how to do this? Thanks!

In general it would be possible, but you should probably switch off row selection to see highlighting immediately. So the code will be about the following:

beforeSelectRow: function () {
    return false;
},
ondblClickRow: function (rowid, iRow, iCol, e) {
    $(e.target).toggleClass('ui-state-highlight');
}

As the result you can have the grid like

UPDATED: If you need select the text in the grid cell you can use the idea described here. In case of usage inside of jqGrid the code could be the following:

var selectText = function (element) {
    var doc = element.ownerDocument, selection, range;
    if (doc.body.createTextRange) { // ms
        range = doc.body.createTextRange();
        range.moveToElementText(element);
        range.select();
    } else if (window.getSelection) {
        selection = window.getSelection();
        if (selection.setBaseAndExtent) { // webkit
            selection.setBaseAndExtent(element, 0, element, 1);
        } else { // moz, opera
            range = doc.createRange();
            range.selectNodeContents(element);
            selection.removeAllRanges();
            selection.addRange(range);
        }
    }
};

$("#list").jqGrid({
    // ... jqGrid options
    ondblClickRow: function (rowid, iRow, iCol, e) {
        selectText(e.target);
    }
});
