[英]Select only one checkbox/radiobutton in the same row and column
我有六列有六個復選框(或單選)。 我的意圖是,在同一行和同一列中只能選擇一個復選框。 例如:當我選擇 column4 和 row3' 中的復選框時,必須立即取消選中 row3 和 column4 中的每個復選框。
我用單選按鈕嘗試過,但我根本做不到,因為每一個收音機總是在兩個不同的組中。
編輯:我的 HTML 代碼:
<div style="position:absolute; left: 20px; top: 20px" class="checkcolumn2" >
<input type="checkbox" ID="column1row1">column1row1<br>
<input type="checkbox" ID="column1row2">column1row2<br>
<input type="checkbox" ID="column1row3">column1row3<br>
<input type="checkbox" ID="column1row4">column1row4<br>
<input type="checkbox" ID="column1row5">column1row5<br>
<input type="checkbox" ID="column1row6">column1row6<br>
</div>
<div style="position:absolute; left: 200px; top: 20px" class="checkcolumn2">
<input type="checkbox" ID="column2row1">column2row1<br>
<input type="checkbox" ID="column2row2">column2row2<br>
<input type="checkbox" ID="column2row3">column2row3<br>
<input type="checkbox" ID="column2row4">column2row4<br>
<input type="checkbox" ID="column2row5">column2row5<br>
<input type="checkbox" ID="column2row6">column2row6<br>
</div>
<div style="position:absolute; left: 380px; top: 20px" class="checkcolumn2">
<input type="checkbox" ID="column3row1">column3row1<br>
<input type="checkbox" ID="column3row2">column3row2<br>
<input type="checkbox" ID="column3row3">column3row3<br>
<input type="checkbox" ID="column3row4">column3row4<br>
<input type="checkbox" ID="column3row5">column3row5<br>
<input type="checkbox" ID="column3row6">column3row6<br>
</div>
<div style="position:absolute; left: 560px; top: 20px" class="checkcolumn2">
<input type="checkbox" ID="column4row1">column4row1<br>
<input type="checkbox" ID="column4row2">column4row2<br>
<input type="checkbox" ID="column4row3">column4row3<br>
<input type="checkbox" ID="column4row4">column4row4<br>
<input type="checkbox" ID="column4row5">column4row5<br>
<input type="checkbox" ID="column4row6">column4row6<br>
</div>
<div style="position:absolute; left: 740px; top: 20px" class="checkcolumn2">
<input type="checkbox" ID="column5row1">column5row1<br>
<input type="checkbox" ID="column5row2">column5row2<br>
<input type="checkbox" ID="column5row3">column5row3<br>
<input type="checkbox" ID="column5row4">column5row4<br>
<input type="checkbox" ID="column5row5">column5row5<br>
<input type="checkbox" ID="column5row6">column5row6<br>
</div>
<div style="position:absolute; left: 920px; top: 20px" class="checkcolumn2">
<input type="checkbox" ID="column6row1">column6row1<br>
<input type="checkbox" ID="column6row2">column6row2<br>
<input type="checkbox" ID="column6row3">column6row3<br>
<input type="checkbox" ID="column6row4">column6row4<br>
<input type="checkbox" ID="column6row5">column6row5<br>
<input type="checkbox" ID="column6row6">column6row6<br>
</div>
這取決於標記。 這是一個簡單的例子:
html
<div>
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
</div>
<div>
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
</div>
<div>
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
</div>
jQuery
$('input[type="checkbox"]').on('change', function() {
// uncheck sibling checkboxes (checkboxes on the same row)
$(this).siblings().prop('checked', false);
// uncheck checkboxes in the same column
$('div').find('input[type="checkbox"]:eq(' + $(this).index() + ')').not(this).prop('checked', false);
});
我不確定這是否是最好的解決方案,但我認為它可以滿足您的需求。
$(":radio").change(function() { // find column var tdColumn = $(this).closest("td"); // find row var trRow = tdColumn.closest("tr"); // uncheck all radios in current row, except the selected radio trRow.find(":radio").not($(this)).prop("checked",false); // index of current column var i = tdColumn.index(); // uncheck all radios in current column, except the selected radio trRow.siblings("tr").each(function(key, value) { $(value).find(":radio")[i].checked = false; } ); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table> <tr> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> </tr> <tr> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> </tr> <tr> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> </tr> <tr> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> </tr> <tr> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> <td> <input type="radio" /> </td> </tr> <table>
我用 3 列和 5 行創建它,但它適用於N列和M 行......只需增加 td 和 tr 標簽......
嘗試這個...
你也可以在這里現場測試;)
結果
..................................................... ..................... ..................................................... ......
jQuery:
$(document).ready(function(){
var $table = $('#MyTable');
var $rowCount = $table.find('tr').length;
var $colCount = $($table.find('tr')[0]).find('td').length;
console.log($rowCount);
console.log($colCount);
$table.find('tr').each(function(i, e){
$tr=$(e);
console.log($tr);
});
});
$(".chBox").click(function() {
console.log('clicked');
$this=$(this);
$row=$this.parent().parent();
$table=$this.closest('table');
$row.find('.chBox').each(function(i, e){
$checkbox=$(e);
$checkbox.prop('checked',false);
console.log($checkbox);
});
$this.prop('checked',true);
var col = $this.parent().parent().children().index($this.parent());
var row = $this.parent().parent().parent().children().index($this.parent().parent());
console.log(col);
console.log(row);
$table.find('tr').each(function(i, e){
$tr=$(e);
$tr.find('.chBox').each(function(k,ex){
$chBox=$(this);
if(k==col && i!=row)
$chBox.prop('checked',false);
});
});
});
HTML:
<table id="MyTable">
<tr>
<td>
<input class='chBox' type="checkbox"/>
</td>
<td>
<input class='chBox' type="checkbox"/>
</td>
<td>
<input class='chBox' type="checkbox"/>

使用 Angular 7 和 JavaScript 在同一行和同一列中僅選擇一個復選框/單選按鈕
這背后的想法是,使用單選按鈕,我們有 name 屬性,它可以按行或列進行單選,但同時針對行和列。 每當單擊按鈕時,我都會將行放在名稱中並使用 javascript 處理列。
這是 HTML 代碼
<section class="editor">
<strong>Editor</strong>
<div>
<label>Add option</label>
<button (click)="addOption()">+</button>
<div *ngFor="let option of options;let i = index">
<span>{{option.title +(i+1)}}</span><button (click)="deleteOption(i)"
*ngIf="options.length>2">X</button>
</div>
</div>
</section>
<hr>
<section>
<strong>Builder</strong>
<div class="builder">
<label>Question title goes here</label><br>
<div *ngFor="let option of options;let row_index = index">
<span>{{option.title +(row_index+1)}}</span>
<span *ngFor="let rank of options;let column_index=index">
<input type="radio" name="{{row_index}}" class="{{column_index}}"
(click)="check(column_index,$event)">
</span>
</div>
</div>
</section>
這是我用 Javascript 實現的 .ts 文件代碼
export class AppComponent {
options = [{
title: "option",
rank: 0,
}, {
title: "option",
rank: 0
}]
constructor() {
}
ngOnInit(): void { }
addOption() {
this.options.push({
title: "option",
rank: 0
})
}
deleteOption(i) {
this.options.splice(i, 1);
}
check(column_index, event) {
Array.from(document.getElementsByClassName(column_index)).map(x=>x['checked']=false);
event.target.checked=true;
}
}
