我们正在使用DHTMLX Grid。需要一些帮助,请。
我有一个表,每列(有过滤器/下拉列表)都分配了一个 id,例如 fac、日期、sel、loc、标签...等
我们已经硬编码了列的索引,以设置并在其他地方获取cookie。
function doInitGrid(){
mygrid.setColumnIds("fac,date,sel,loc,tag"); //set ids
mygrid.attachEvent("onFilterStart",function(ind,data)
{
setCookie("Tray_fac_filter",mygrid.getFilterElement(0).value,365); //column index 0
setCookie("Tray_loc_filter",mygrid.getFilterElement(3).value,365);//column index 3
setCookie("Tray_tag_filter",mygrid.getFilterElement(4).value,365); //column index 4
mygrid.getFilterElement(0).value = getCookie("Tray_fac_filter")
mygrid.getFilterElement(3).value = getCookie("Tray_dep_filter")
mygrid.getFilterElement(4).value = getCookie("Tray_prg_filter")
});
}
但是当列被移动时,随着列的索引更改,问题就会出现,但它是在setCookie/getCoookie中设置
的。DHTMLX 允许使用 -- 获取 id 的索引 --
var colInd = grid.getColIndexById(id);
eg: var colInd = grid.getColIndexById(date); // outputs 1.
After moving the date column to the end -- fac, sel, loc, tag, date // it will output 4.
但是,我们有大约 14 列可以移动/重新排列,我可以使用
var colInd = grid.getColIndexById(id); 15 times
var facInd = grid.getColIndexById("fac");
var dateInd = grid.getColIndexById("date");
var selInd = grid.getColIndexById("sel");
var locInd = grid.getColIndexById("loc";
var tagInd = grid.getColIndexById("tag");
并将这些变量放入设置/获取 cookie 中。我在想是否有更好的方法。
为了更好地理解代码,我将代码的最小化版本放在小提琴中。

我认为你有最好的答案。 循环执行,这样更容易:
var cookie_prefix = "Fray_filter_";
var cookie_dur = 365;
var num_cols = dhx_grid.getColumnCount();
// filter vals to cookies
for (var col_idx=0; col_idx<num_cols; col_idx++) {
var filter = mygrid.getFilterElement(col_idx)
if (filter) { // not all columns may have a filter
var col_id = dhx_grid.getColumnId(col_idx);
var cookie_name = cookie_prefix+col_id;
setCookie(cookie_name, filter.value, cookie_dur);
}
}
// cookies to filter vals
for (var col_idx=0; col_idx<num_cols; col_idx++) {
var col_id = dhx_grid.getColumnId(col_idx);
var filter_val = getCookie(cookie_prefix+col_id);
var filter = mygrid.getFilterElement(col_idx)
filter.value = filter_val;
}
dhtmlxgrid 本机事件在每次移动列时分配正确的 id。该事件称为 onAfterCMove,您可以在此处查看文档。onAfterCMove Event
你会做这样的事情:
mygrid.attachEvent('onAfterCMove',function(cInd,posInd){
//Your processing here to change the cookies; where cInd is the index of the column moved
//and posInd, is the position where it Was moved
}):
