问题
I want the logic after the top header checkbox is clicked to be different. Currently (I am using custom formatter) it selects all first level rows.
I want the click to select/deselect all rows that are NOT a parent. Or at least not to select the parent rows.
In current set up parent row tree toggle on click and then is deselected.
custom formatter looks like that. To be honest I do not understand the code. I tried to put console.log to every addEventListener in below definition but it was not triggered.
I guess the answer might be in registerHeaderSelectCheckbox but I have no idea how to use it.
Working jsFiddle for trying out.
formatter: function(cell, formatterParams, onRendered) {
const data = cell.getRow().getData();
if (do_not_show_checkbox_ids.indexOf(data['id']) == -1) {
var checkbox = document.createElement("input");
checkbox.type = 'checkbox';
if (this.table.modExists("selectRow", true)) {
checkbox.addEventListener("click", (e) => {
e.stopPropagation();
});
if (typeof cell.getRow == 'function') {
var row = cell.getRow();
if (row._getSelf().type == "row") {
checkbox.addEventListener("change", (e) => {
row.toggleSelect();
});
checkbox.checked = row.isSelected && row.isSelected();
this.table.modules.selectRow.registerRowSelectCheckbox(row, checkbox);
} else {
checkbox = "";
}
} else {
checkbox.addEventListener("change", (e) => {
if (this.table.modules.selectRow.selectedRows.length) {
this.table.deselectRow();
} else {
this.table.selectRow(formatterParams.rowRange);
}
});
this.table.modules.selectRow.registerHeaderSelectCheckbox(checkbox);
}
}
return checkbox;
}
return null;
},
回答1:
titleFormatter option is for header row checkbox and formatter option is for rows checkbox
var do_not_show_checkbox_ids = [1];
function customFormatter(isHeader = false) {
return function(cell, formatterParams, onRendered) {
var checkbox = null;
// check if selectable is true in options
if (this.table.modExists("selectRow", true)) {
checkbox = document.createElement("input");
checkbox.type = 'checkbox';
// add click event in checkbox
checkbox.addEventListener("click", (e) => {
console.log('header', isHeader);
e.stopPropagation();
});
// check if cell has getRow function if yes then it may be row
if (typeof cell.getRow == 'function') {
// get cell row
var row = cell.getRow();
// get cell data for condition testing
const data = cell.getData();
// if is row and not skippable id
if (row._getSelf().type == "row" && do_not_show_checkbox_ids.indexOf(data['id']) == -1) {
// add change event to toggle cell row
checkbox.addEventListener("change", (e) => {
row.toggleSelect();
});
// update checkbox after row toggle
checkbox.checked = row.isSelected && row.isSelected();
// registering for if row clicked from anywhere then checkbox check/uncheck
this.table.modules.selectRow.registerRowSelectCheckbox(row, checkbox);
} else {
// if is row and skippable id
checkbox = "";
}
} else {
// header checkbox then add change addEventListener for selecting/deselecting all rows.
checkbox.addEventListener("change", (e) => {
// get all rows
this.table.getRows().forEach(row => {
// get row nodes/children
row.getTreeChildren().forEach(child => {
// check if child selected if yes then deselect else select
child.isSelected() ? child.deselect() : child.select();
})
});
// for selecting/deselecting all rows
// if (this.table.modules.selectRow.selectedRows.length) {
// console.log('header', isHeader);
// this.table.deselectRow();
// } else {
// this.table.selectRow(formatterParams.rowRange);
// }
});
// updating internal header checkbox
this.table.modules.selectRow.registerHeaderSelectCheckbox(checkbox);
