Question

我试图从jquery插件中调用一个函数。

示例代码为：

$("#table-2").tableDnD({
    onDragClass: "myDragClass",

    onDrop: function(table, row) {
        var rows = table.tBodies[0].rows;
        var debugStr = "Row dropped was "+row.id+". New order: ";
        for (var i=0; i<rows.length; i++) {
            debugStr += rows[i].id+" ";
        }
        $(#debugArea).html(debugStr);
    },

    onDragStart: function(table, row) {
        $(#debugArea).html("Started dragging row "+row.id);
    }
});

取自http://isocra.com/2008/02/table-drag-and-drop-jquery-plugin/的onDrop的定义是

onDrop

传递删除行时将调用的函数。该函数有2个参数：表和被删除的行。您可以使用来计算行的新顺序 table.tBodies [0] .rows。

是否可以将功能传递给它？例如：

onDrop: doWork(table, row),

doWork在哪里：

function doWork (table, row) {
  var row_id = $(row).prop('id');
}

错误是： Uncaught ReferenceError: table is not defined(…)与我为doDrop添加的行有关。

任何人都知道这样做？感谢。

Answer 1

写作时

onDrop: doWork(table, row),

您使用这些参数调用函数doWork。由于table不存在，它会抛出错误。

正确的做法是

onDrop: doWork,

这样您就可以设置要调用的功能。
