While upgrading from jqrid4.6 to 4.13.5 facing iss

问题:

Trying to create a demo to show dynamic dropdown for Field-source, client but data is returning null.

When I try to upgrade from 4.6 to 4.13.5 .. my existing dynamic dropdown unique values get disturbed.

回答1:

The current code has some simple errors like the usage of $("grid") instead of $("#grid") inside of getUniqueNames and setSearchSelect and creating filterToolbar before filling searchoptions.value with the data: you call applyColumnFilterOnGrid after filterToolbar instead of before filterToolbar.

The next problem exists in the buildSearchSelect, which I published originally in the old answer. You changed the line

values += ";" + this + ":" + this;

to

values += "," + this + ":" + this;

which is wrong. One should use ; instead of , as the separator (see the documentation of jqGrid 4.6). If you replace "," to ";" then the problem will be solved. In general you can use , instead of ; as the separator in the value, but you should inform jqGrid about that by usage delimiter: "," option:

var setSearchSelect = function(columnName) {

    $("#grid").jqGrid("setColProp", columnName,
                {
                    stype:"select",
                    searchoptions: {
                        delimiter: ",",
                        value:buildSearchSelect(getUniqueNames.call("#grid",columnName)),
                        sopt:["eq"]
                    }
                }
    );
};
