合並1個字符串和一個int值，同時將id值賦予<button>在HTML中動態生成</button>的<button>字段</button>

Question

var but = document.createElement('span');

        but.innerHTML.id="but1"+inc;

        but.innerHTML = '<button value="delete row" id="'but'+inc"  
onclick="deleteRow(this.id)">delete row</button>';

// '"but"+inc' , "but+inc" are not working

//here inc is an integer value which increments by one

Answer 1

這是錯的

  but.innerHTML.id="but1"+inc;

這應該是這樣

  but.id="but1"+inc;

  but.innerHTML = '<button value="delete row" id="but'+inc+'" onclick="deleteRow(this.id)">delete row</button>';
