防止在线编辑模式下编辑特定可编辑行的单元格

The value of the property editable is common for all rows, but the value will be used only by editRow method which initialize inline editing. So you can change the value of editable property dynamically with respect of setColProp (like in the answer). It's important that you set the correct value of the editable property before every call of editRow. In the answer you can see corresponding code example and the demo.

更新:如果你使用 formatter: "actions" 那么你可以子类化" $.fn.fmatter.rowactions 调用onclick 处理程序.下面你可以看到相应代码的示例

UPDATED: If you use formatter: "actions" then you can "subclass" the $.fn.fmatter.rowactions called in onclick handler. Below you can see an example of the corresponding code

var orgRowActions = $.fn.fmatter.rowactions;
$.fn.fmatter.rowactions = function (rid, gid, act, pos) {
    var $grid = $("#" + $.jgrid.jqID(gid)),
        rowData = $grid.jqGrid("getLocalRow", rid),
        isNonEditable = false,
        result;
    // we can test any condition and change
    // editable property of any column
    if (act === "edit" && parseFloat(String(rowData.tax)) <= 20) {
        $grid.jqGrid("setColProp", "note", {editable: false});
        isNonEditable = true;
    }
    result = orgRowActions.call(this, rid, gid, act, pos);
    if (isNonEditable) {
        // reset the setting to original state
        $grid.jqGrid("setColProp", "note", {editable: true});
    }
    return result;
}

您可以在这里找到相应的演示.只有当tax"列中的值是<= 20时，note"列才可在演示中

The corresponding demo you will find here. The "note" column is editable in the demo only if the value from the "tax" column is <= 20:

如果你有 datatype: "json" 或 datatype: "xml" 而不使用 loadonce: true 你应该替换调用getLocalRow 对上述代码中getRowData 或getCell 的调用.

If you would have datatype: "json" or datatype: "xml" without usage of loadonce: true you should replace call of getLocalRow to the call of getRowData or getCell in the above code.
