实现这一点的方法是构建我自己的列模型,我可以再次保存和解析,并且只保存必要的属性。
这种方法很容易受到 XSS 攻击,因为我正在评估函数,但它是一个可行的解决方案。
columnsApi: {
key: null,
grid: null,
newColumnModel: {
headerName: "",
width: 200,
valueGetter: "",
filter: 'text',
aggFunc: 'none',
filterParams: {apply: true}
},
setKey: function (key) {
this.key = key;
},
setGrid: function (grid) {
this.grid = grid;
},
format: function (columns) {
var format = [];
angular.forEach(columns, function (col) {
var colDef = {
width: col.actualWidth,
pinned: col.pinned,
hide: !col.visible
};
format.push(angular.extend(col.colDef, colDef));
});
return format;
},
getIDs: function (columns) {
var ids = [];
angular.forEach(columns, function (col) {
ids.push(col.colId);
});
return ids;
},
stringify: function (columns) {
return JSON.stringify(columns, function (key, value) {
if (typeof value === "function")
return "/Function(" + value.toString() + ")/";
return value;
});
},
parse: function (string) {
return JSON.parse(string, function (key, value) {
if (typeof value === "string" &&
value.startsWith("/Function(") &&
value.endsWith(")/")) {
value = value.substring(10, value.length - 2);
return eval("(" + value + ")");
}
return value;
});
},
add: function (column) {
if (this.grid === null) {
console.error("Assertion error: grid must not be null");
return;
}
if(column.aggFunc == 'none')
column.aggFunc = undefined;
var groups = this.get().groups;
var newColumns = this.format(getGridColumns(this.grid));
newColumns.push(column);
this.grid.api.setColumnDefs(newColumns);
this.setGroups(groups);
},
save: function () {
var self = this;
if (this.key === null) {
console.error("Assertion error: key must not be null");
return;
}
if (this.grid === null) {
console.error("Assertion error: grid must not be null");
return;
}
var savedOptions = {
columns: self.format(getGridColumns(self.grid)),
groups: self.getIDs(self.grid.columnApi.getRowGroupColumns()),
sorting: self.grid.api.getSortModel(),
filter: self.grid.api.getFilterModel()
};
localStorage.setItem(this.key, this.stringify(savedOptions));
},
// Get function uses "eval" - XSS vulnerable.
get: function () {
if (this.key === null) {
console.error("Assertion error: key must not be null");
return;
}
var options = localStorage.getItem(this.key);
if (options)
options = this.parse(options);
return options;
},
remove: function (field) {
if (this.grid === null) {
console.error("Assertion error: grid must not be null");
return;
}
var newColumns = this.format(getGridColumns(this.grid));
angular.forEach(newColumns, function (col, key) {
if (col.field == field)
newColumns.splice(key, 1);
});
this.grid.api.setColumnDefs(newColumns);
},
setGroups: function (groups) {
var self = this;
angular.forEach(groups, function (id) {
angular.forEach(getGridColumns(self.grid), function (col) {
if (col.colId == id)
self.grid.columnApi.addRowGroupColumn(col);
});
});
}
}
我相信这个解决方案是为 Ag-Grid 5 编写的,因此我不确定它是否仍然有效。
