This article mainly brings you a JQuery to obtain the text content (example) of multiple select tag options. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

According to the id attribute of the option, modify the text value


$("#sel_p .select_class option[id='-选择省-']").text(data.province).attr("selected",true);
 $("#sel_p .select_class option[id='-选择市-']").text( data.city).attr("selected",true);
 $("#sel_p .select_class option[id='-选择区-']").text( data.area).attr("selected",true);
 $("#sel_p .select_class option[id='-选择街-']").text( data.street).attr("selected",true);

Get all the items under multiple selects (use the class attribute, the values ​​are the same) The text value of option


$("#sel_p .select_class option").each(function(){ //遍历所有option标签

   var text = $(this).text(); //获取option的text
   alert(text);//显示的是当前这个option的text值
   if(txt == "选择省")
     $("#sel_p .select_class option[id='-选择省-']").text(data.province).attr("selected",true);
   if(txt == "选择市")
     $("#sel_p .select_class option[id='-选择市-']").text( data.city).attr("selected",true);
   if(txt == "选择区")
     $("#sel_p .select_class option[id='-选择区-']").text( data.area).attr("selected",true);
  if(txt == "选择街")
     $("#sel_p .select_class option[id='-选择街-']").text( data.street).attr("selected",true);

 });

If there is no cascading relationship in the select, then all options have been loaded, and you can use the following method to display the queried data


$("#sel_p .select_class option[id="+data.province+"]").attr("selected",true);
$("#sel_p .select_class option[id="+data.city+"]").attr("selected",true);
$("#sel_p .select_class option[id="+data.area+"]").attr("selected",true);
$("#sel_p .select_class option[id="+data.street+"]").attr("selected",true);

Another way to get all options is equivalent to spelling all the text into a string and storing each character in the map


var map = $("#sel_p .select_class option").map(function(){

    alert($(this).text());//显示单个option的text  text1

    return $(this).text();
  }).get().join(",");

alert(map);//显示的是 text1,text2,text3
alert(map[0]);//显示 t

Improve on the above basis, use array array to store the queried data, and use for loop to operate the data


var array = new Array();
  $("#leaf .form-control option").map(function(){
    array.push($(this).text());
  })
  for(var i = 0; i < array.length; i ++ ){
    alert(array[i]);//显示每个option的text  text1,text2,text3
  }
