在我的情况下,它需要激活选项01作为默认选择.它使用checked = true属性,但值不与formControlName ="options"绑定,当用户选择任何选项时它绑定.如果没有任何用户选择选项值显示为"null".
<div class="row">
<mat-radio-group formControlName="options">
<mat-radio-button checked=true value="1">Option 01</mat-radio-button>
<mat-radio-button value="2">Option 02</mat-radio-button>
</mat-radio-group>
</div>

请帮我解决这个问题.谢谢.
我正在使用以下代码从html表生成excel文件,对于小规模数据集工作正常,当涉及到大html表数据集时,它显示下载错误。
//creating a temporary HTML link element (they support setting file names)
var a = document.createElement('a');
//getting data from our div that contains the HTML table
var data_type = 'data:application/vnd.ms-excel';
var table_div = document.getElementById('dataTable');
var table_html = table_div.outerHTML.replace(/ /g, '%20');
a.href = data_type + ', ' + table_html;
//setting the file name
a.download = 'Sample.xls';
//triggering the function
a.click();
//just in case, prevent default behaviour
e.preventDefault();
