You can't get text box in this way. Here is the work-around I hope it will help.
您无法以这种方式获取文本框。这是解决方法，我希望它会有所帮助。
function GVtxtAmount() {
var GVMaintainReceiptMaster = document.getElementById('<%= GVMaintainReceiptMaster.ClientID %>');
for (var rowId = 1; rowId < GVMaintainReceiptMaster.rows.length; rowId++) {
var txtbx = GVMaintainReceiptMaster.rows[rowId].cells[0].children[0];
alert(txtbx.value);
}
return false;
}
