How to set the text value of select in jquery

jQuery is a popular JavaScript library that greatly simplifies JavaScript programming. In the process of web development, it is often necessary to set the text value of select. This article will introduce how to use jQuery to achieve this function.

First of all, you need to understand the related operations of select in jQuery. In jQuery, you can use the val() method to get and set the value of select. For example, the following code can get the value of select:

var selectedValue = $("select").val();

In addition, if you want to set the value of select, you can do it by setting the parameters of the val() method. For example, the following code can set the value of select to "1":

$("select").val("1");

But what if you want to set the text value of select? In jQuery, you can use the text() method to set the text content of an element. For the select element, its text content is the text content of the option element. Therefore, we can traverse all option elements, find the option element that needs to be set, and then set its text content.

The following is the specific implementation method:

//假设需要设置的select选择器是#mySelect，需要设置的文本内容是"Apple"
$("#mySelect option").each(function() {
  if ($(this).html() === "Apple") {
    $(this).text("Apple"); // 设置文本内容
    $(this).attr('selected', true); // 选中该option元素
  }
});

In the above code, first use the each() method to traverse all option elements. If the option element that needs to be set is found, use text() method to set its text content, and use the attr() method to set the option element to the selected state. If the option element that needs to be set is not found, the code will continue to execute the next loop.

It should be noted that the text() method can only set the text content of the element, but not the attributes or styles. If you need to set attributes or styles, you should use the attr() or css() method.

In general, it is not difficult to use jQuery to set the text value of select. You only need to traverse the option element and find the element that needs to be set. I hope this article can help readers who need to solve this problem.
