推荐答案

我试过并获得文本框的ID，如 var masterTable = I tried and got the ID of the textbox like var masterTable =

find（<％= gvtemp。 ClientID％>）。get_masterTableView（）; var row = masterTable.get_dataItems（）; var ids = new Array（row）; for（var i = 0;我< row.length; i ++）{ var rowid = masterTable.get_dataItems（）[i] .findElement（txtDescription）。id; ids [i] = rowid; } find("<%= gvtemp.ClientID %>").get_masterTableView(); var row = masterTable.get_dataItems(); var ids = new Array(row); for (var i = 0; i < row.length; i++) { var rowid = masterTable.get_dataItems()[i].findElement("txtDescription").id; ids[i] = rowid; }
